Introduction. COVID-19, an epidemic of coronavirus infection, has become a major global threat. The coronavirus mainly targets the human respiratory system, followed by cytokine storm, and altered immune responses associated with disease progression and adverse outcomes. Sumac and pomegranate juice are rich in bioactive compounds, which potentially have antiviral activities. This study is aimed at investigating the effect of a diet based on the use of sumac and pomegranate juice on the treatment of outpatients with COVID-19. Methods. In this study, 182 outpatients with COVID-19 were randomly divided into two groups receiving a diet containing pomegranate juice and sumac along with standard treatment and the control group (group 2) receiving standard treatment. Results. Consumption of a diet containing pomegranate juice and sumac in outpatients with COVID-19, who were receiving standard-of-care treatment, led to a significant decrease in fever, chills, cough, weakness, smell and taste disorders, shortness of breath, diarrhea, nausea and vomiting, and abdominal pain compared with outpatients with COVID-19 who received only standard treatment. Conclusion. Clinical trials of outpatients have limitations such as patients’ resilience to post-COVID-19 follow-up. However, the use of pomegranate juice and sumac can be efficacious in reducing COVID-19 symptoms. This trial is registered with IRCT20190406043175N3.

Application of the aroma extract dilution analysis (AEDA) on a distillate prepared from freshly squeezed juice of Dornfelder grapes revealed (3

In the present study, 20 lactic acid bacteria (LAB) were isolated from different fruit juices, milk, and milk products. Based on preliminary screening methods like emulsification index, oil displacement method, hemolysis, and reduction in surface tension, strain LNH70 was selected for further studies. Further, it was evaluated for preliminary probiotic characteristics, identified by 16 s rRNA sequencing as Lactococcus lactis, submitted to NCBI, and an accession number was obtained (MH174454). In addition, LNH70 was found to tolerate over wide range of temperatures (10-45 °C), pH (3-10), NaCl (up to 9%), bile (0.7%), and phenol (0.1%) concentrations. Further, optimization studies at flask level revealed that lactose as carbon source, peptone as organic nitrogen, and inorganic nitrogen (ammonium sulfate) enhanced biosurfactant production. Chemical composition of purified biosurfactant obtained from LNH70 was characterized by various physico-chemical analytical techniques and identified as xylolipid. Xylolipid biosurfactant exhibited anti-adhesion activity against food borne pathogens in in vitro conditions. Its anti-oxidative property by 1, 1-diphenyl-2-picrylhydrazyl (DPPH), 2, 2'-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid (ABTS), and ferric reducing antioxidant power (FRAP) radical scavenging activity was found in range of 60.76 ± 0.5 to 83.50 ± 0.73%. Furthermore, xylolipid (0.05, 0.1, 0.3 mg/mL) when used for its potential as orange and pineapple juices preservation revealed miniature changes in the physico-chemical parameters evaluated in this study. However, the microbial population slightly lowered when xylolipid was used at 0.3 mg/mL after 5th day. Hence, this study supports the potential use of biosurfactant from L. lactis for its application as food preservative.

Pineapple juice is preferred by consumers for its unique aroma and flavor that come from a set of amino acids, amines, phenolic compounds, and furanone. The juice is susceptible to spoilage, and a common practice is to pasteurize it at 70-95°C for 0.5-5 min. However, the characteristic flavors and phytochemicals are negatively influenced by the intense time-temperature treatment. To retain the thermosensitive compounds in the juice, some nonthermal technologies such as high-pressure processing, pulsed electric field, pulsed light, ultrasound, and ultraviolet treatments have been explored. These techniques ensured microbial safety (5-log reduction in E. coli, S. Typhimurium, or S. cerevisiae) while preserving a maximum ascorbic acid (84-99%) in the juice. The shelf life of these nonthermally treated juice varied between 14 days (UV treated at 7.5 mJ/cm

"High-pressure processing (HPP) plus" combined technologies are applied to overcome the limitation of single HPP and to produce juices with more stable quality during storage. This research explored the potential of HPP in combination with centrifugation to produce cloud stable orange juice during refrigerated storage. The results indicated that HPP combined processing technology significantly improved the cloud stability of orange juice, which was related to removed large particles, reduced viscosity, decreased protein contents, and inactivated pectin methylesterase activity induced by centrifugation (P 0.05). Besides, chelator solubilized pectin (CSP) decreased but water solubilized pectin (WSP) maintained in the juice after centrifugation. During storage, the conversion of pectin fraction from WSP to CSP, resulting in sedimentation appeared in centrifugation treated orange juice when stored for 28 days. In general, pectin characteristics changes and pectin fractions conversion were the main driving forces affecting cloud stability of orange juice pasteurized by HPP in combination with centrifugation and during chilled storage.

Fruit and fruit juices are a valuable source of bioactive compounds, which can protect our organisms from oxidative stress. The phenolic compounds and other phytochemicals may affect the antimicrobial properties of juices. The aim of this study has been to evaluate antioxidant and antimicrobial properties of selected berry juices and vitamin C-rich fruit juices. The research material was composed of seven juices, including three from berries (elderberry chokeberry, cranberry), three from vitamin C-rich fruit (sea buckthorn, wild rose, Japanese quince) and one exotic juice from noni fruit. Antioxidant capacity, total polyphenol, total flavonoid and total anthocyanin content were determined. Furthermore, the antimicrobial activity and the minimal inhibitory concentration (MIC) as well as the minimal bactericidal concentration (MBC) were evaluated. The research showed that fruit juices from wild rose, chokeberry and Japanese quince had the highest antioxidant capacity. These juices were characterised by the rich content of polyphenols. Elderberry and chokeberry juices had the highest total anthocyanins. The juices differed in the content of bioactive compounds and specific bactericidal properties against Gram-positive or Gram-negative bacteria. Fruit juices from cranberry, Japanese quince and sea buckthorn had the highest antimicrobial activity. Wild rose, chokeberry and elderberry juices, despite their high antioxidant properties, showed antimicrobial activity only against Gram-positive strains, except Enterococcus faecalis and Clostridium perfringens. Significant differences in the content of bioactive compounds in fruit juices affect the antimicrobial properties juices.

Fruit intake, including consumption of 100% fruit juice, is generally associated with a better diet quality and overall health. However, fruit and vegetable intakes are below recommendations in many countries.The present study examined fruit juice intake and total energy and nutrient intakes according to juice consumption or non-consumption in participants in the National Dietary and Nutrition Survey Rolling Programme 2014-2016 in the UK (n = 2723) and the Individual and National Study on Food Consumption 2006-2007 (n = 4079) in France. Total energy and nutrient intakes were also estimated for scenarios in which orange juice with pomace was either added to the daily diet or replaced 100% orange juice or beverages containing fruit juice.Fruit juice consumers had higher intakes of fruits and vegetables than non-consumers, were more likely to reach 5-a-day targets for fruit and vegetable consumption, and had significantly higher intakes of folate, vitamin C, potassium, magnesium, and fibre. Juice consumers also had higher total energy and sugar intakes, but lower body mass index than non-juice consumers. Modelling consumption of orange juice with pomace increased fibre and potassium intakes in orange juice consumers, and also increased fibre, most micronutrients, and 5-a-day achievements in non-juice consumers.These national survey results demonstrate that fruit juice consumers in the UK and France had higher intakes of fruits and vegetables than fruit juice non-consumers, and significantly higher intakes of several micronutrients and fibre. Furthermore, modelling of consumption of orange juice with pomace increased fibre and select micronutrient intakes, particularly among fruit juice non-consumers.

A vortex-assisted dispersive micro-solid-phase extraction procedure using a new and green sorbent was developed as a simple, fast, and efficient sample preparation method for the extracting five pesticides in several fruit juice samples. In this study, for the first time, riboflavin was used as an efficient sorbent. A few milligrams of riboflavin was directly added into the aqueous solution containing the analytes to adsorb them. After adsorption the analytes, they were desorbed and more concentrated by a dispersive liquid-liquid microextraction procedure. The influence of several effective parameters such as amount of riboflavin, pH, vortex time, eluent nature and volume, and extraction solvent type and volume on the extraction efficiency was investigated. In optimal conditions, linear ranges of the calibration curves were broad. The limits of detection and quantification were attained in the ranges of 0.56-1.5 and 1.9-0.52 ng mL

The color of sugarcane juice has a great influence on the preferences of consumers. The contents of pigments, sugars, free amino acids, organic acids, phenolic compounds, enzyme activities, antioxidant activities, and color differences among juices produced from four sugarcane varieties were investigated in this study. The data suggested that variety played an important role in the color and chemicophysical properties of sugarcane juice. The color of four varieties of sugarcane juice varied from greenish yellow to light brown. Bamboo cane juice and black rind sugarcane juice presented similar color properties and both had high contents of phenolic compounds and strong antioxidant activities. Yellow rind sugarcane juice with higher value of L* (26.10) and more pigment contents than the other varieties was attractive. Sucrose, glucose, β-alanine, chlorogenic acid, p-hydroxybenzoic acid, isochlorogenic acid, DPPH, and polyphenol oxidase activity had positive correlations with a* value. The effects of organic acids on color were limited. PRACTICAL APPLICATION: This study demonstrated the relationships between color parameters and contents of pigments, sugars, free amino acids, organic acids, phenolics, enzyme activities, and antioxidant activities of sugarcane juice. This could help to find out the coloration mechanisms of sugarcane juice. Our manuscript created a paradigm for future studies on color control during juice processing and storage.

To determine the impact of educational intervention in reducing the consumption of sugar-sweetened beverages (SSBs) and 100% fruit juice in children and adolescents.We conducted a comprehensive Ovid Medline and Scopus search. Articles had to be peer-reviewed, full-text and published in English. Studies had to be controlled intervention, published between 1 January 2010 to 7 February 2021, and in children and adolescents. Study quality was measured using the Quality Assessment Tool for Controlled Intervention Studies.Forty intervention articles were included in this review involving 25,069 children and adolescents. All studies employed a quantitative research method using the Randomized Controlled Trial designs. Twenty-eight out of forty interventions used psychosocial theories. Study quality ranged from 'fair' to 'good.' Results showed that education intervention effectively reduced SSBs, and reduced 100% fruit juice in children.Reducing the SSBs consumption in children should be initiated by conducting school-based programs consisting of interactive learning process, psychosocial theories and the involvement of parents or caregivers. Theories that focus on personal, behavior and environment factors improve the effectiveness of the intervention. More research is warranted to investigate the impacts of 100% fruit juice on obesity, dental caries and risk of co-morbidities in children.

Cherry juice has become a standard component of athlete recovery strategies. This review covers the history of cherry juice as a recovery drink to give context to its current use. Fifteen studies were identified that included a measure of muscle function, soreness, or inflammation on the days following exercise and had an exercise insult sufficient to assess the effectiveness of the tart cherry intervention. Eight studies used a concentrated juice, three used a juice from fresh-frozen cherries, two used a tart cherry concentrate gel, and two used a tart cherry powder. The effective juice dose was specific to the type of drink (fresh-frozen versus concentrate) but dose-response studies are lacking, and thus, the optimal dose for any specific type of cherry juice is not known. Timing of the dosing regimen is a critical factor. Studies have uniformly shown that muscle function will recover faster on the days after exercise if juice is provided for several days prior to exercise. Effects on soreness or systemic inflammation are more equivocal. The available evidence does not support a regimen that begins on the day of exercise or post-exercise. Tart cherry powder did not enhance any metric of recovery on the days after exercise. In conclusion, the term recovery implies an intervention that is introduced after an exercise insult. The term “precovery” may be preferable to describe interventions that should be introduced on the days prior to exercise to facilitate recovery on the days after exercise. The evidence supports cherry juice as a precovery intervention across a range of athletic activities.

AIMS Patients with type 2 diabetes mellitus (T2DM) have reduced vasodilatory responses during exercise partially attributable to low nitric oxide (NO) levels. Low NO contributes to greater α-adrenergic mediated vasoconstriction in contracting skeletal muscle. We hypothesized boosting NO bioavailability via 8wks of active beetroot juice (BRA, 4.03 mmol nitrate, 0.29 mmol nitrite, n = 19) improves hyperemia, via reduced α-mediated vasoconstriction, during handgrip exercise relative to nitrate/nitrite-depleted beetroot juice (BRP, n = 18) in patients with T2DM. METHODS Forearm blood flow (FBF) and vascular conductance (FVC) were calculated at rest and during handgrip exercise (20%max, 20contractions·min-1). Phenylephrine (α1-agonist) and dexmedetomidine (α2-agonist) were infused intra-arterially during independent trials to determine the influence of α-mediated vasoconstriction on exercise hyperemia. Vasoconstriction was quantified as the percent-reduction in FVC during α-agonist infusion, relative to pre-infusion, as well as the absolute change in %FVC during exercise relative to the respective rest trial (magnitude of sympatholysis). RESULTS ΔFBF (156 ± 69 to 175 ± 73 ml min-1) and ΔFVC (130 ± 54 to 156 ± 63 ml min-1·100 mmHg-1, both P

Fruit juice is one of the most popular drinks, which requires strict processing conditions to ensure its quality, especially to prevent enzymatic browning and turbidity loss. In this work, a new strategy for the preparation of composite nanofibers for juice clarification and anti-browning control was proposed. The strategy used microfluidic spinning to combine Fucoxanthin (Fx), hydroxypropyl-γ-cyclodextrin (HP-γ-CD) and polyvinyl pyrrolidone (PVP) to prepare Fx/HP-γ-CD-PVP (PCF) nanofibers, which not only reflected the excellent antioxidant properties of cyclodextrin-wrapped Fx, but also achieved a more optimized juice clarification agent dosage. Molecular docking technique was used to prove that the stable inclusion complex of Fx and HP-γ-CD could be formed by hydrogen bonding when the molar ratio of Fx to HP-γ-CD was 1 : 2, and the binding energy was as low as -10.23 kcal mol

Fruits are the most important source of polyphenols, substances that have a positive effect on human health. Modern technologies for the industrial processing of fruits into juice are aimed at preserving the useful components of the raw material in it. The issue of the content of polyphenols in industrial juice products, and, especially, changes in their concentration over time, is important for understanding the nutritional value of juice products and requires further study.

Dietary nitrate, found predominantly in green leafy vegetables and other vegetables such as radish, celery, and beetroot, has been shown to beneficially modulate inflammatory processes and immune cell function in animals and healthy individuals. The impact of increased nitrate intake on soluble inflammatory mediators in individuals with hypertension is unclear. We assessed whether the daily consumption of dietary nitrate

We have developed an HPLC-UV method for the determination of pyrroloquinoline quinone (PQQ), which utilizes a redox-based colorimetric reaction. In the proposed colorimetric reaction, the redox reaction between PQQ and dithiothreitol generates superoxide anion radicals that can convert 2-(4-iodophenyl)-3-(4-nitrophenyl)-5-phenyl-2H-tetrazolium chloride (INT) to formazan dye. After PQQ separation on an octadecyl silica column, it was mixed online with dithiothreitol and INT, and the formed formazan dye was monitored by absorbance at 490 nm. The detection limit (S/N = 3) of the proposed method was 7.6 nM (152 fmol/injection). The proposed method could selectively detect PQQ in food products without any clean-up procedures.

Here we attempted to deliver probiotics to the human gut using fruit juices as a carrier, which is less common despite the newest trend to incorporate probiotics into non-dairy food. Phenolic-rich fruit juices, including blueberry, black cherry, concord grape and pomegranate were fortified with

The work, Methods for determination of sugars in sweetened non-alcoholic beverages: systematic review, represents an opportunity to promote a better knowledge about the methods applied to the sugars determination in non-alcoholic beverages through the accomplishment of a systematic review (SR).

Introduction: Intake of acidic beverages has been considered one of the factors that can cause tooth erosion. In an attempt to reduce the erosive potential of these beverages for dental enamel, it is possible to add anti-erosion agents to them. Objective: To map which are the anti-erosion substances that, when added to liquid acidic beverages suitable for consumption, reduce the erosive potential of tooth enamel. Review Method: This is a scoping review protocol according to the Joanna Briggs Institute method. The research question was constructed using the Population, Concept and Context (PCC) strategy, with P - dental element; o C - anti-erosion substances added to liquid acid drinks suitable for consumption, to reduce the erosive potential; and C - dental enamel. Based on the PCC, the following research question was elaborated: What are the anti-erosion substances that, when added to liquid acidic beverages suitable for consumption, reduce the erosive potential of dental enamel?. Publications that meet the following inclusion criteria will be considered included: Scientific articles that present primary data written in English and published until December 2022; and studies of the in situ type in which the evaluation of erosion is at the enamel level of permanent human teeth and acidic drinks are suitable for consumption. The following exclusion criteria will be considered: Studies that do not correlate with the guiding question; duplicates; and studies related to powdered beverages. A detailed, individual and high sensitivity search strategy will be used for each of the selected databases, namely PubMed (Medline), Virtual Health Library, EMBASE (Elsevier), Scopus (Elsevier), Web of Science and ScienceDirect (Elsevier). Two reviewers will carry out the searches, sorting by titles and abstracts, eligibility by reading the studies in full and, subsequently, extracting data from the included studies. Presentation and Interpretation of Results: The data will be segmented into several categories involving identification, methodology and main results, which will be arranged in tables. After careful analysis of the findings, discussions will be carried out seeking to synthesize and consolidate evidence in a rigorous and effective way.

Star fruit toxicity has been hugely described in patients with chronic kidney disease, either on conservative or renal replacement therapy. This is a case report of a man, without prior kidney or neurological dysfunction, who appeared to develop nephrotoxicity and neurotoxicity less than 12 hours after drinking concentrated star fruit juice (approximately 20 units of the fruit). He received timely renal replacement therapy and renal function fully recovered after discharge.

Pulsed light (PL) is a polychromatic radiation-based technology, among many other non-thermal processing techniques. The microbiological lethality of the PL technique has been explored in different food matrices along with their associated mechanisms. Pasteurization of fruit juice requires a 5-log cycle reduction in the resistant pathogen in the product. The manufacturers look toward achieving the microbial safety and stability of the juice, while consumers demand high-quality juice. Enzymatic spoilage in fruit juice is also a crucial factor that needs attention. The retailers want the processed juice to be stable, which can be achieved by inactivating the spoilage enzymes and native microflora inside it. The present review argued about the potential of PL technology to produce a microbiologically safe and enzymatically stable fruit juice with a minimal loss in bioactive compounds in the product. Concise information of factors affecting the PL treatment (PLT), primary inactivation mechanism associated with microorganisms, enzymes, the effect of PLT on various quality attributes (microorganisms, spoilage enzymes, bioactive components, sensory properties, color), and shelf life of fruit juices has been put forward. The potential of PL integrated with other non-thermal and mild thermal technologies on the microbial safety and stability of fruit juices has been corroborated. The review also provides suggestions to the readers for designing, modeling, and optimizing the PLT and discusses the use of various primary, secondary kinetic models in detail that have been utilized for different quality parameters in juices. Finally, the challenges and future need associated with PL technology has been summarized.

Mycotoxins are frequently found in fruits and fruit juices. However, data about occurrence and fate of mycotoxins along the fruit juice processing chain are currently insufficient. Herein, a liquid chromatographic/tandem mass spectrometric (LC–MS/MS) multi-mycotoxin method was developed and applied to investigate the effect of technological unit operations on the fate of three of the most relevant mycotoxins along the processing chain for cloudy and clear apple juice, namely patulin (PAT), ochratoxin A (OTA), and alternariol (AOH). Raw juice obtained directly after dejuicing was spiked with the aforementioned mycotoxins at pilot-plant scale prior to subjecting it to different technological unit operations. Regarding clear apple juice production treatment with a pectinolytic enzyme preparation, and pasteurization were insignificant for mycotoxin reduction, but fining with subsequent filtration was effective, although the mycotoxins showed different affinity towards the tested agents. The most effective fining agent was activated charcoal/bentonite in combination with ultrafiltration, which removed OTA (54 µg/L) and AOH (79 µg/L) to not quantifiable amounts (limit of quantification (LOQ) 1.4 and 4.6 µg/L, respectively), while PAT was reduced only by 20% (from 396 to 318 µg/L). Regarding cloudy apple juice production, all studied processing steps such as centrifugation and pasteurization were ineffective in reducing mycotoxin levels. In brief, none of the common steps of clear and cloudy apple juice production represented a fully effective safety step for minimizing or even eliminating common mycotoxins. Thus, ensuring the sole use of sound apples should be of utmost importance for processors, particularly for those manufacturing cloudy juices.

The aim of this systematic review was to provide the required information regarding different aspects of the relationship between epilepsy/antiseizure medications and non-alcoholic drinks. The recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement were followed. MEDLINE and Scopus from the inception until 7 August 2021 were systematically searched. These key words were used: "epilepsy" OR "seizure" OR "antiepileptic" OR "antiseizure" OR "anticonvulsant" AND "coffee" OR "tea" OR "soda" OR "juice" OR "drink" OR "cola" OR "diet" (35 key word combinations). The primary search yielded 21 458 publications (PubMed, n = 4778; Scopus, n = 16 680). Only 50 studies met all the inclusion criteria and were included in the current systematic review. In total, 17 articles investigated various non-alcoholic drinks in human studies, 11 studies were case reports/series, and 22 articles were animal/in vitro studies. None of the studies provided a class 1 of evidence. There is limited evidence suggesting that certain drinks (eg, caffeinated energy drinks) might trigger seizures. Patients with epilepsy should avoid excessive consumption of certain fruit juices (eg, grapefruit, lime, pomegranate, kinnow, and star fruit) and caffeinated drinks. However, daily coffee and tea intake can be part of a healthy balanced diet, and their consumption does not need to be stopped in patients with epilepsy. Coffee/tea consumption is not harmful if consumed at levels of 200 mg (caffeine) in one sitting (about 2½ cups of coffee) or 400 mg daily (about five cups of coffee).

A high volume of fluid can strongly reduce a drug's concentration in urine. Therefore, to detect diluted samples the concentration of creatinine in urine is determined during testing drugs of abuse. If the concentration is below 20 mg creatinine/dL urine, the urine sample is usually rejected for drug testing. It should be examined whether creatine or creatinine ingestion can mask urine dilution by increasing the creatinine concentration. A total of 18 subjects drank 1.3 L of water and 0.2 L of orange juice on each of the three testing days: 1. without creatine, 2. with 20 g of creatine, 3. with 20 g of creatine following incubation for four days in orange juice at room temperature; an acidic environment should promote conversion of creatine to creatinine. The lowest creatinine concentrations in urine were observed on average two hours after fluid intake. At that time, ingestion of fluid without creatine, with creatine, and with creatine (ine)-orange juice mixture resulted in mean values of 11.6, 22.5, and 28.3 mg creatinine/dL urine, respectively. It can be concluded that ingestion of creatine or creatinine can increase the concentration of creatinine in urine and thus mask dilution of a sample. The conversion of creatine in orange juice further increases availability of creatinine as it is obvious from urine creatinine concentration. Therefore, creatine ingestion during drug testing will give rise to negative results due to matrix adulteration. In a case of suspected creatine supplementation, the creatine content of the sample should be determined in addition to creatinine.

lt;bgt;Background and Objective:lt;/bgt; Obesity exerts negative influences on male reproductive capacity via changing the molecular and physical structure of male germ cells. This study was conducted to evaluate the mitigating effects of raw juice of pineapple on obesity-associated testicular impairment in male Wistar rats.lt;bgt;Materials and Methods:lt;/bgt; Rats included the control group (Glt;subgt;Ilt;/subgt;, n = 6) who received a Normal Diet (ND) and the obese group (Glt;subgt;IIlt;/subgt;, n = 18) who received a High-Fat Diet (HFD). Obese rats (Glt;subgt;IIlt;/subgt;) were subdivided into 3 groups (6 rats each): Glt;subgt;IIlt;/subgt; represents the untreated obesity group that continued to receive HFD with plain Drinking Water (DW), Glt;subgt;IIIlt;/subgt; received ND along with raw juice (15% v/v) in DW and Glt;subgt;IVlt;/subgt; continued to receive HFD with raw juice (15% v/v) in DW. Rats were sacrificed at the end of the trial and testis was processed for histopathology and immunohistochemistry.lt;bgt;Results:lt;/bgt; Testis from obese rats revealed a significant increment in spermatogenic cell degeneration, pro-inflammatory Nuclear factor of kappa B (NF-κB) and pro-apoptotic Caspase-3 immunoreactivities. Yet, Proliferating Cell Nuclear Antigen (PCNA) displayed poor immunoreactivity in obese rats' testis relative to controls. Administration of raw juice of pineapple to obese rats significantly reduced degeneration of spermatogenic cells, NF-κB and Caspase-3 immunoreactivities. Additionally, treatment with the juice significantly increased immunoreactivity to PCNA in obese rats. These ameliorating effects were more obvious in rats who received juice along with ND (Glt;subgt;IIIlt;/subgt;) than in those who received it along with HFD (Glt;subgt;IVlt;/subgt;).lt;bgt;Conclusion:lt;/bgt; Treatment of obese rats with pineapple juice restored testicular homeostasis, indicating its potential validity to overcome obesity-induced male fertility disorders.

Poly(dimethylsiloxane)-based thin-film sorbent sheets (SPMESH) have previously been used for parallel headspace (HS) extraction prior to direct analysis in real-time mass spectrometry (DART-MS) for rapid quantitation of odorants in complex matrices. However, HS-SPMESH extraction is poorly suited for less volatile odorants, e.g., volatile phenols. This report describes modifications to the previous SPMESH extraction device, which make it amenable to parallel extraction of low-volatility analytes from multiwell plates under direct immersion (DI) conditions. Optimization and validation of the DI-SPMESH-DART-MS approach were performed on four volatile phenols (4-ethylphenol, 4-ethylguaiacol, 4-methylguaiacol, and guaiacol) of relevance to the quality of grape juices. Negative-ion mode DART-MS spectra showed a series of oxygenated adducts [M + nO - H]- for all analytes, but isobaric interferences could be limited for three of the four analytes by selecting an appropriate MS/MS transition. Signal suppression from nonvolatiles (sugars, acids) could be overcome by a rinse step. DI-SPMESH-DART-MS analysis of 24 samples could be performed in ∼45 min (30 min extraction, 16 min DART analysis) with 0.5-3 μg/L detection limits in aqueous and model juice solutions. In real grape juices (n = 5 cultivars), good accuracy (72-137%) could be achieved for two of the four volatile phenols initially investigated, 4-ethylphenol and 4-ethylguaiacol. However, poor accuracy was observed for guaiacol in some cultivars, and 4-methylguaiacol could not be quantitated due to interferences with other volatile phenols. Despite these limitations, DI-SPMESH-DART-MS/MS may be useful for prescreening a large number of samples prior to more selective conventional analyses.

Summary Background & aims This study aimed to determine the prospective relationship between the consumption of sugar-sweetened beverages (SSBs) and 100% fruit juice and metabolic syndrome (MetS) and to investigate whether weight change can modify this association in a representative sample of the population of Tehran, Iran. Methods In this 8.9-year follow-up study, the consumption of SSBs and 100% fruit juice by 1915 individuals, who participated in Tehran Lipid and Glucose Study (TLGS), was examined using a validated food frequency questionnaire. The MetS was defined according to the Joint Interim Statement. Participants were categorized as those who lost weight (≥-2%), those with weight stability (−1.9%–1.9%), and those who gained weight (≥2%). The Cox regression model was used to determine the relationship between the consumption of SSBs and 100% fruit juice and the risk of MetS and weight gain ≥2%. Also, the modifying effect of weight change including weight loss, weight stability and weight gain on the relationship between SSBs and 100% fruit juice consumption and the incidence of MetS was assessed. Results There was no significant association between the consumption of SSBs and the risk of MetS in the crude model; however, after adjustments for confounders, a significant positive association was found between the consumption of SSBs and the risk of MetS (HR: 1.33; 95% CI: 1.07–1.66). Also, no significant association was observed between the consumption of 100% fruit juice and the risk of MetS in the crude model. However, after adjustments for the potential confounders, 100% fruit juice was inversely associated with the MetS risk (HR: 0.78; 95% CI: 0.63–0.95). The consumption of SSBs and 100% fruit juice was positively associated with weight gain (≥2% during the follow-up). Nevertheless, after adjustments for lifestyle and dietary factors, there was no significant association between the consumption of SSBs and weight gain. On the other hand, the consumption of 100% fruit juice was positively associated with the increased risk of weight gain (HR: 1.41; 95% CI: 1.20–1.65). Among participants with weight loss, the first, second and third tertiles of 100% fruit juice reduced the risk of MetS by 29% (HR: 0.71; 95% CI: 0.51–0.99), 47% (HR: 0.53; 95% CI: 0.37–0.75) and 35% (HR: 0.65; 95% CI: 0.46–0.92), respectively. Conclusion Although 100% fruit juice reduced the risk of MetS, its consumption must be limited due to its positive effect on weight gain. On the other hand, the consumption of 100% fruit juice reduced the risk of MetS, depending on the individual's weight change. Also, high consumption of SSBs was associated with the incidence of MetS.

Recent postharvest studies have shown that adding an antioxidative agent in a polysaccharide-based edible coating reduces postharvest losses and extends the shelf life of a coated fruit. Therefore, the effect of addition of ascorbic acid (AA, 1%) in chitosan-based coating (CH, 1%) on strawberry fruits under cold storage conditions at 4 ± 1 °C and 85 ± 5% RH was investigated for 15 days. It was observed that addition of AA in CH coating reduced weight loss, decay percentage, malondialdehyde content and hydrogen peroxide compared to CH alone. The combined CH + AA application also suppressed fruit softening by reducing cell wall degrading enzymes (i.e. polygalacturonase, cellulase and pectin methyl esterase) activities. In addition, AA incorporation catalyzed ROS scavenging enzymes (i.e. ascorbate peroxidase, catalase, peroxidase and superoxide dismutase) activities. CH + AA treatment also maintained fruit quality by conserving higher total soluble solids, titratable acidity, ascorbic acid content, total phenolics and antioxidant activity. Sensory quality (color, taste, glossiness and overall acceptability) of fruits coated with CH + AA treatment was also stable during storage. Conclusively, the combined CH + AA application is an effective approach to maintain the postharvest quality of strawberry fruits under cold storage.

The occurrence of nonenzymaticbrowning in fruit juices during storage is a major quality defect. It negatively affects consumer acceptance and consumption behavior and determines the shelf-life of these products. Although nonenzymatic browning of fruit juices has been the subject of research for a long time, the exact mechanism of the nonenzymatic browning reactions is not yet completely understood. This review paper aims to give an overview of the compounds and reactions playing a key role in nonenzymatic browning during the storage of fruit juices. The chemistry of the plausible reactions and their relative importance will be discussed. To better understand nonenzymatic browning, factors affecting these reactions will be reviewed and several strategies and methods to evaluate color changes and browning will be discussed. Nonenzymatic browning involves three main reactions: ascorbic acid degradation, acid-catalyzed sugar degradation, and Maillard-associated reactions. The most important NEB pathway depends on the matrix. Nonenzymatic browning is affected by many factors, such as the juice composition, the pH, the oxygen availability (packaging material), and the storage conditions. Nonenzymatic browning can thus be considered as a complex problem. To characterize color changes and browning and obtain insight into the browning mechanism of fruit juices, food scientists applied several approaches and strategies. These included the use of model systems with/without the addition of labeled compound and real systems as well as advanced analytical methods. ispartof: COMPREHENSIVE REVIEWS IN FOOD SCIENCE AND FOOD SAFETY vol:20 issue:6 pages:5698-5721 ispartof: location:United States status: published

Sleep is considered as one of the most important aspects for maintaining a healthy life. For a person to function normally, at least 6-8 hours of sleep daily is necessary. Sleep not only affects our mood, but also regulates the efficiency of work done. Many complications arise due to inadequacy of sleep. The unhealthy food and lifestyle choices have made us more prone to sleep disorders. The medications used for the treatment of sleep disorders are mainly habit forming and have tendencies of withdrawal symptoms. This inadequacy in medication has lead to search for newer, better options. The field of nutraceuticals fits apt for treating such disorders. The quality of being non-toxic, non-habit forming, and being practically more efficient has had made it an excellent option. Nutraceuticals make use of food or part of food for the treatment or to prevent any disease. Remarkable positive effects of nutraceuticals like Caffeine, Chamomile, Kava kava, Cherries and Cherry juice, L tryptophan, Valerian, Vitamin D, Marijuana, melatonin, Lemon balm had been mentioned in the treatment of sleep disorders. The present review gives a general overview of nutraceuticals and discusses their use in sleep disorders.

Pomegranate juice (PJ) has potential positive effects in patients with metabolic disturbances due to a high content of polyphenols. The objective of this study was to evaluate effects of a 2-week consumption of dietary doses of PJ on blood pressure, lipid metabolism, and oxidative stress markers in overweight patients with dyslipidemia. Twenty-four patients, 8 males and 16 females, 40-60 years of age, with established overweight and dyslipidemia were randomly assigned into intervention group, who consumed 300 mL of PJ daily for 2 weeks, or control group. After 2 weeks of juice intake, intervention group had significantly lower diastolic blood pressure, low-density lipoprotein cholesterol, aminotransferase, and activity of glutathione peroxidase. Furthermore, patients who consumed PJ had reduced percentage of docosahexaenoic acid (22:6n-3, DHA) in plasma phospholipids and increased estimated activity of stearoyl-CoA desaturase. In erythrocytes, we found a significant increase in the levels of dihomo-gamma- linolenic acid (20:3n-6, DGLA) and DHA, as well as in estimated activity of Delta 6 desaturase, and a decrease in estimated activity of Delta 5 desaturase. These results show that even a short-term consumption of dietary doses of PJ exerts beneficial effects and affects lipid metabolism in overweight patients with dyslipidemia.

PURPOSE: The aim was to investigate the effect of dietary nitrate supplementation (in the form of beetroot juice, BRJ) for 20 days on salivary nitrite (a potential precursor of bioactive nitric oxide), exercise performance and high altitude (HA) acclimatisation in field conditions (hypobaric hypoxia). METHODS: This was a single-blinded randomised control study of 22 healthy adult participants (12 men, 10 women, mean age 28 ± 12 years) across a HA military expedition. Participants were randomised pre-ascent to receive two 70 ml dose per day of either BRJ (~12.5 mmol nitrate per day; n = 11) or non-nitrate calorie matched control (n = 11). Participants ingested supplement doses daily, beginning 3 days prior to departure and continued until the highest sleeping altitude (4800 m) reached on day 17 of the expedition. Data were collected at baseline (44 m altitude), at 2350 m (day 9), 3400 m (day 12) and 4800 m (day 17). RESULTS: BRJ enhanced the salivary levels of nitrite (p = 0.007). There was a significant decrease in peripheral oxygen saturation and there were increases in heart rate, diastolic blood pressure, and rating of perceived exertion with increasing altitude (p=

Cognitive decline, anxiety, and depression are significant contributors to human ill health and decreased quality of life. Intake of fruits including 100% juice is associated with beneficial effects on several health outcomes. The current study explored the potential associations between consumption of 100% fruit juice and neurocognitive markers in adults. Twenty-four-hour dietary recall data from the National Health and Nutrition Examination Survey (NHANES) 1988–1994, 1999–2018 for adults 20+ years (N = 62,606) were used to assess 100% fruit juice intake, and NHANES questionnaire data were used for the assessment of neurocognition. Association of usual intake of 100% fruit juice with neurocognitive outcomes were assessed by regression analysis after adjusting for demographic, lifestyle, dietary, and health-related covariates. About 21% of adults were fruit juice consumers and the intake was a little over 2 oz per day. Consumers of 100% fruit juice had 16.3% fewer days per month of feeling anxious compared to non-consumers. There were no significant associations of 100% fruit juice usual intake with other neurocognitive measures. A large number of potential confounding variables have been identified to be associated with one or more neurocognitive measures suggesting that these may be important parameters to include in future studies.

The purpose of this study was to test the hypothesis that acute intake of inorganic nitrate (NO3−) via supplementation would attenuate the venoconstriction and pressor response to exercise. Sixteen healthy young adults were assigned in a randomized crossover design to receive beetroot juice (BRJ) or an NO3−-depleted control beverage (prune juice: CON). Two hours after consuming the allocated beverage, participants rested in the supine position. Following the baseline period of 4 min, static handgrip exercise of the left hand was performed at 30% of the maximal voluntary contraction for 2 min. Mean arterial pressure (MAP) and heart rate (HR) were measured. Changes in venous volume in the right forearm and right calf were also measured using venous occlusion plethysmography while cuffs on the upper arm and thigh were inflated constantly to 30–40 mmHg. The plasma NO3− concentration was elevated with BRJ intake (p < 0.05). Exercise increased MAP and HR and decreased venous volume in the forearm and calf, but there were no differences between CON and BRJ. Thus, these findings suggest that acute BRJ intake does not alter the sympathetic venoconstriction in the non-exercising limbs and MAP response to exercise in healthy young adults, despite the enhanced activity of nitric oxide.

The theoretical screening and design of green solvents to reduce organic solvents and to develop green and efficient sample pretreatment methods have attracted extensive attention. Here, benzimidazoles (BZDs) with potential reproductive toxicity were used as target compounds, and amino acid ionic liquids (AAILs) were designed and selected via a theoretical calculation. With the functionalized AAIL as monomers, and POSS as the crosslinking agent, novel specific magnetic nanoparticles (Fe

Carrot is a popular vegetable consumed by people of all age groups and is used in various food products because of its high nutritional content, especially vitamin A.In the present study, colorful fresh carrot juices of 12 carrot varieties were investigated for in vitro antidiabetic, anti-aging, and anti-obesity activities with antioxidant potential by ABTS (2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) and FRAP (ferric reducing ability of plasma) assays. The studied juices were also compared for physicochemical characteristics: titratable acidity, pH, pectin content, total soluble solids, dry mass, ash, viscosity, turbidity, osmolality, and color. The results of the study showed that normal purple carrot juice exhibited the best activities in all biological and antioxidant tests, except for anti-α-glucosidase activity. Normal purple carrot juice also had the highest total mineral content with elevated results for titratable acidity, pH, total soluble solids, dry mass, ash, viscosity, and osmolality.Purple carrot juices demonstrated elevated health-promoting activities and could be used in blended beverage recipes to attract children's attention. The results of sensorial characteristics (appearance, color, and taste) of juices, however, showed that people are more familiar with orange carrot products. © 2022 Society of Chemical Industry.

Background Pomegranate juice has gained attention for its health properties, becoming consequently a highly demanded product. The revival of the pomegranate in Italy, as in other Mediterranean countries, starts with the planting of new intensive orchards characterized by both the new cultivation technique and new varieties. As a result of growing demand and high productivity, pomegranate could become an interesting crop to diversify farm income. This study seeks to determine the aril juice quality attributes and bioactive compounds of six pomegranate cultivars ('Mollar', 'Dente di cavallo', 'Acco', 'Jolly red', 'Wonderful' and 'Wonderful Super') and two local ecotypes ('Eco BA' and 'Eco FG') grown in Apulia region, southern Italy. Results The aril juices were evaluated for their main physicochemical properties (yield, color, pH, total soluble solids content, titratable acidity, sugar-acid ratio), chemical and bioactive compounds (vitamin C, phenolics, anthocyanins and antioxidant activities). 'Eco BA', 'Mollar' and 'Jolly red' genotypes were characterized by the highest maturity index, and then could be considered to be sweet-sour in taste. Total phenols and antioxidant activity were higher in 'Dente di cavallo' and 'Eco FG' genotypes. 'Eco FG' was also the richest in vitamin C, punicalagin and ellagic acids, while 'Dente di cavallo', 'Acco' and 'Wonderful' showed the highest content of the detected anthocyanin compounds. Conclusion These results contribute to current knowledge about chemical composition, phenolic contents, anthocyanin profiles and antioxidant activity of pomegranate juice from different genotypes, showing in most cases an appreciable juice quality and bioactive profile, although significant differences among them were detected. © 2021 The Authors.

Peripheral artery disease (PAD) is characterized by the accumulation of atherosclerotic plaques in the lower extremity conduit arteries, which impairs blood flow and walking capacity. Dietary nitrate has been used to reduce blood pressure (BP) and improve walking capacity in PAD. However, a standardized dose for PAD has not been determined. Therefore, we sought to determine the effects of a body mass-normalized moderate dose of nitrate (0.11 mmol nitrate/kg) as beetroot juice on serum nitrate/nitrite, vascular function, walking capacity, and tissue oxygen utilization capacity in patients with PAD. A total of 11 patients with PAD received either nitrate supplement or placebo in a randomized crossover design. Total serum nitrate/nitrite, resting BP, brachial and popliteal artery endothelial function (flow-mediated dilation, FMD), arterial stiffness (pulse-wave velocity, PWV), augmentation index (AIx), maximal walking distance and time, claudication onset time, and skeletal muscle oxygen utilization were measured pre- and postnitrate and placebo intake. There were significant group × time interactions ( P < 0.05) for serum nitrate/nitrite, FMD, BP, walking distance and time, and skeletal muscle oxygen utilization. The nitrate group showed significantly increased serum nitrate/nitrite (Δ1.32 μM), increased brachial and popliteal FMD (Δ1.3% and Δ1.7%, respectively), reduced peripheral and central systolic BP (Δ−4.7 mmHg and Δ−8.2 mmHg, respectively), increased maximal walking distance (Δ92.7 m) and time (Δ56.3 s), and reduced deoxygenated hemoglobin during walking. There were no changes in PWV, AIx, or claudication ( P > 0.05). These results indicate that a body-mass normalized moderate dose of nitrate may be effective and safe for reducing BP, improving endothelial function, and improving walking capacity in patients with PAD.

Patients may have difficulty swallowing a whole daily dose of 240 mg (4 × 60‐mg tablets) of apalutamide. One of the unique properties of apalutamide tablets is easy disintegration and dispersion when mixed into aqueous vehicles, avoiding the need to crush/split the tablets. To evaluate whether this method of apalutamide tablet administration would be conducive in a patient setting, different variations in preparation were evaluated, and one preparation was tested in humans. In vitro compatibility studies evaluated purity, dose, or stability of different variations of apalutamide in applesauce/yogurt/orange juice/green tea. An open‐label, randomized, crossover phase 1 study in healthy men determined the bioavailability of an apalutamide‐applesauce mixture versus whole tablets based on maximum plasma analyte concentration (Cmax), area under the plasma analyte concentration‐time curve: AUC0‐72h and AUC0‐168h. Different amounts of applesauce/yogurt/orange juice/green tea as well as durations (up to 6 hours) did not affect the total apalutamide content available. The phase 1 study (n = 12) showed increased total exposure of 5% and peak exposure of 27.6% when comparing the apalutamide‐applesauce mixture with whole‐tablet administration. Variations in preparation times and total content for applesauce/yogurt/orange juice/green tea did not affect the purity, dose, or stability of apalutamide. An apalutamide‐applesauce mixture is a suitable alternative administration method to whole tablets.

The aim of this study is to investigate the use of ultrasound pretreatment as potential technique to solubilize organic matter and fermentation of fruit juice effluents in anaerobic batch reactor. The efficacy of ultrasound pretreatment has been assessed at low frequency of 20 kHz and at different sonication times (20, 40 and 60 min). Compared with control, the amount of biogas produced increased by 47, 57 and 60% for sonication times of 20, 40 and 60 min, respectively. Methane content of the produced biogas was about 59% in the control and 64% in the case of effluent subjected to ultrasonication for 60 min. After 20 days of anaerobic digestion of the fruit juice effluents, the efficiency of chemical oxygen demand (COD) increased by 9, 31 and 35% with respect to control for sonication times of 20, 40 and 60 min, respectively, corresponding to total sugars uptake efficiency of about 35, 51 and 54%, respectively. The modified Gompertz equation was used to describe the cumulative biogas production. A good agreement was found between simulated and experimental data. HIGHLIGHTS Biogas production from fruit juice processing industry.; Ultrasound pretreatment to improve biogas production.; High methane content is obtained for prolonged sonication time.; The COD removal increased by 35% for sonication time of 60 min.

BACKGROUND: Juices are currently a fast-growing segment in the fruit and vegetable industry sector. However, there are still no reports on the diversity of the phytochemical profile and health-promoting properties of commercial sea buckthorn (Hippophaë rhamnoides) juices. This study aimed to identify and quantify phytoprostanes, phytofurans by ultra high-performance liquid chromatography coupled with triple quadrupole mass spectrometry (UHPLC-QqQ-MS/MS), tocopherols, tocotrienols by ultra-performance liquid chromatography coupled with a fluorescence detector (UPLC-FL), carotenoids, and free amino acids by ultra-performance liquid chromatography coupled with a photodiode detector-quadrupole and tandem time-of-flight mass spectrometry (UPLC-PDA-Q/TOF-MS), and assess their anti-cholinergic, anti-diabetic, anti-obesity, anti-inflammatory, and antioxidant potential by in vitro assays of commercial sea buckthorn juices. RESULTS: Phytoprostanes (PhytoPs) and phytofurans (PhytoFs) in sea buckthorn juices were identified for the first time. Juices contained eight F-, D-, B- and L-phytoprostanes and one phytofuran (32.31–1523.51 ng and up to 101.47 μg/100 g dry weight (DW)), four tocopherol congeners (22.23–94.08 mg 100 g DW) and three tocotrienols (5.93–25.34 mg 100 g DW). Eighteen carotenoids were identified, including ten xanthophylls, seven carotenes and phytofluene, at a concentration of 133.65 to 839.89 mg 100 g DW. Among the 20 amino acids (175.92–1822.60 mg 100 g DW), asparagine was dominant, and essential and conditionally essential amino acids constituted 11 to 41% of the total. The anti-enzyme and antioxidant potential of juices correlated selectively with the composition. CONCLUSION: Sea buckthorn juice can be a valuable dietary source of vitamins E and A, oxylipins and amino acids, used in the prevention of metabolic syndrome, inflammation, and neurodegenerative processes. The differentiation of the composition and the bioactive potential of commercial juices indicate that, for the consumer, it should be important to choose juices from the declared berry cultivars and crops. © 2021 Society of Chemical Industry., The research was supported by the Ministry of Science and Higher Education of Poland, under the Diamond Grant project no.

The aim of our study was to investigate the effects of single-dose Ougan (Citrus reticulata cv. Suavissima) juice application on the pharmacokinetics of erlotinib in vivo. Twelve Sprague-Dawley rats were randomly divided into the Ougan juice and control groups ( n = 6 each). The rats were given a single dose of 1 mL/100 g Ougan juice or 1 mL/100 g normal saline (NS) by intragastric administration, followed by a single oral administration of 20 mg/kg erlotinib. The plasma concentration of erlotinib in rats was determined using ultra performance liquid chromatography–tandem mass spectrometry (UPLC-MS/MS). Erlotinib-d6 was used as the internal standard for chromatographic analysis on the UPLC BEH C18 analysis column ( 2.1 mm × 50 mm , 1.7 μm). The mobile phase was composed of acetonitrile and 0.1% formic acid eluting by gradient. Different pharmacokinetic (PK) parameters of erlotinib were calculated. The Ougan juice promoted the absorption of erlotinib and reduced the clearance of the drug. The area under the curve of erlotinib in the single-dose Ougan juice pretreatment group was approximately 1.87 times higher, and the maximum blood concentration (Cmax) was approximately 1.34 times higher than that in the control group. The mean residence time of erlotinib in the Ougan juice group was larger, and the clearance rate was smaller than those in the control group; the difference was statistically significant ( P < 0.05 ). Ougan juice affected the PK spectrum of erlotinib in rats by improving the bioavailability of the drug and significantly increasing its plasma concentration.

Context Fruit, but not fruit juice, intake is inversely associated with type 2 diabetes mellitus (T2DM). However, questions remain about the mechanisms by which fruits may confer protection. Objective The aims of this work were to examine associations between intake of fruit types and 1) measures of glucose tolerance and insulin sensitivity and 2) diabetes at follow-up. Methods Among participants of the Australian Diabetes, Obesity and Lifestyle Study, fruit and fruit juice intake was assessed by food frequency questionnaire at baseline. Associations between fruit and fruit juice intake and 1) fasting plasma glucose, 2-hour postload plasma glucose, updated homeostasis model assessment of insulin resistance of β-cell function (HOMA2-%β), HOMA2 of insulin sensitivity (HOMA2-%S), and fasting insulin levels at baseline and 2) the presence of diabetes at follow-up (5 and 12 years) were assessed using restricted cubic splines in logistic and linear regression models. Results This population of 7675 Australians (45% males) had a mean ± SD age of 54 ± 12 years at baseline. Total fruit intake was inversely associated with serum insulin and HOMA2-%β, and positively associated with HOMA2-%S at baseline. Compared to participants with the lowest intakes (quartile 1), participants with moderate total fruit intakes (quartile 3) had 36% lower odds of having diabetes at 5 years (odds ratio, 0.64; 95% CI, 0.44-0.92), after adjusting for dietary and lifestyle confounders. Associations with 12-year outcomes were not statistically significant. Conclusion A healthy diet including whole fruits, but not fruit juice, may play a role in mitigating T2DM risk.

Background Fiber is an important part of a healthy diet and is known to attenuate postprandial glycemia. Orange pomace (OP) is a by-product of orange juice (OJ) production and is a rich source of fiber. Objective Two separate studies determined the impact of added OP to 100% OJ on postprandial glycemic response compared with sugar-matched OJ or whole orange fruit (WOF). Methods Study 1 included 17 adults [65% female, age 39.3 ± 3.1 y, and BMI (in kg/m2) 24.6 ± 0.7], and study 2 included 45 different adults (47% female, age 25.1 ± 4.3 y, and BMI 22.5 ± 1.6). Studies were conducted at separate locations using a randomized, 3-arm, crossover design to test the glycemic response to sugar-matched OJ, OJ with 5 g fiber from OP (OPF), or WOF. The primary outcomes were 2-h glucose incremental area under the curve (iAUC) in study 1, analyzed by repeated measures ANOVA, and maximum glucose concentration (Cmax) in study 2, analyzed using PROC MIXED (ANCOVA). Glucose and insulin concentrations were measured at fasting and multiple time points over 2 h after test product consumption (study 1, serum; study 2, plasma). Results In study 1, glucose iAUC was not significantly lower in OPF compared to the OJ or WOF (825 ± 132 compared with 920 ± 132 and 760 ± 132 mg · min · dL-1, respectively, P = 0.57 for both). In study 2, glucose iAUC was significantly lower in WOF compared with OPF and OJ (689 ± 70.7 compared with 892 ± 70.7 and 974 ± 70.7 mg · min · dL-1, P = 0.02 and 0.001, respectively). Data from both studies indicated OPF reduced Cmax compared with OJ and that the reductions were comparable to WOF (study 1: OPF, 115 ± 4.06 compared with OJ, 124 ± 4.06 and WOF, 114 ± 4.06 mg · dL-¹, P = 0.002 and 0.75, respectively; study 2: OPF, 128 ± 1.92 compared with OJ, 136 ± 1.92 and WOF, 125 ± 1.92 mg · dL-¹, P = 0.001 and 0.28, respectively). Conclusion Data from both studies demonstrated no significant effect of OPF on postprandial iAUC compared with OJ. However, adding OP into OJ attenuates the postprandial glucose Cmax, and the responses were comparable to WOF in healthy adults.

The current study assessed the risk posed to Iranian consumers by oral exposure to a mixture of 20 pesticides and six metals in 96 fruit juice (FJ) samples (3 batches × 4 brands × 8 types of FJs) collected from Iran market. Concentrations of metals and pesticides in FJs were quantified by inductively coupled plasma-optical emission spectrometry (ICP-OES) and chromatography-mass spectrometry (GC-MS), respectively. The mean concentration of all pesticides was below the maximum residue limits (MRLs) set by the European Union (EU). The calculated target hazard quotients (THQs) and total hazard index (HI) were1.0 for all pesticides residue, indicating no risk. For the carcinogenic metals (As, Ni, and Pb), estimated incremental lifetime cancer risks (ILCRs) at the 50th and 95th centiles were respectively 4.25 × 10

The survival of bacteria in the sports drink and orange juice remaining in and at the mouth of bottles after direct drinking was examined after immediately drinking and incubation at 37 °C for 24 h.Nine healthy participants were asked to drink approximately 100 mL of a plastic bottled sports drink or orange juice. The samples were cultured anaerobically at 37 °C for 7 days. Genomic DNA was extracted from the resulting individual colonies, and bacterial species were identified using 16 S rRNA gene sequencing.The mean amount of bacteria in the remaining sports drink and orange juice, immediately after drinking, were (1.6 ± 2.3) × 10The bacterial levels differed significantly from the previously reported levels in bottled tea 24 h after drinking, suggesting that remaining drinks with low pH levels can be preserved for a longer period.
