The demand for functional beverages is expanding over the world. In this work, a rapid, easy and low-cost procedure was followed to prepare a functional beverage (FB) by directly using two-phase olive pomace (TPOP). Liquid ingredients (water and 6% citric acid), extraction systems (heat and ultrasonic treatment), treatment time (30, 60, 90 min) and drying techniques (freeze and air-dried) were studied. Experimented TPOP had a total phenol content of 7.5 mg/g CAE (caffeic acid equivalent), composed majorly of o-diphenols. Air drying of TPOP caused a 50% depletion of total phenols compared to freeze drying. Conversely, no substantial differences were found in the FB, neither for liquid ingredients nor treatment/time adopted. Both 6% citric acid and water were revealed to be profitable liquid ingredients. A 30-min heating treatment was enough to produce a satisfactory beverage, whereas ultrasound treatment caused a loss of total phenols, especially in the water FB. All FBs appeared just limpid after a simple filtration; the citric acid beverage showed reddish color, while water ones were brownish. Finally, the prepared FBs had an average total phenol of about 600 mg/L CAE (by using 300 g/L fresh pomace), with hydroxytyrosol and related compounds being well represented, which confirmed their potential functionality.

Cucurbita ficifolia is an edible plant whose fruits have hypoglycemic, anti-inflammatory, and antioxidant activities. Fermentation might improve these properties. This research aims to perform and characterize its fermentation in native and induced conditions with Lactobacillus plantarum (Lp) and evaluate its antioxidant activity and effect on glycemia. Fresh juice from mature fruits was characterized. One portion of this juice was spontaneously left to ferment (native fermentation), and the other was inoculated with Lp (controlled fermentation). Fermentation was monitored each 8 h by 56 h to measure microbial growth, pH, acidity, sugars, soluble protein, polyphenols and flavonoids, antioxidant activity, and effects on glycemia. In native fermentation, the growth of total microorganisms increased up to 32 h, decreasing at the end of the process. In Lp fermentation, total microorganisms increased until 16 h to stay constant at the end, with a predominance of Lp. The pH and the sugars decreased in the two fermentations, while polyphenol and flavonoid increased. In spontaneous fermentation, these changes were lesser. Both fermentations, like fresh juice, preserve functional properties (antioxidant, alpha-glucosidase inhibition, and hypoglycemia). The fermentation of this juice with Lp may develop functional beverages, which is significant due to its consumption as an edible fruit with medicinal properties. [ABSTRACT FROM AUTHOR]

Wort can be used as a basis for functional beverages production because of its content of fibres, antioxidants and vitamins. The biological value of wort depends on the malt used and the mashing regime. Therefore, we investigated the main brewing characteristics (extract, pH, and colour), phenolic compounds content, and antioxidant activity (measured by DPPH, FRAP, CUPRAC, ABTS, and ORAC) of wort, produced by Vienna, Melanoidin, Caramel pils and Special X malt or mixture of them. The results obtained were used for the modelling and optimisation of malt mixture that can be used for the production of functional beverages. Optimisation was made on the basis of wort extract, total phenolic compounds (measured by Folin–Ciocalteu method), and antioxidant activity, measured by DPPH, FRAP, and ORAC methods. Although optimised variants with high content of Special X malt showed highest antioxidant activity, they had an unpleasant taste and slow mash filtration rate. Therefore, the variant with 24.2% Vienna, 51.8% Melanoidin, 20% Caramel pils, and 4% Special X malts was chosen for the production of functional wort-based beverages. [ABSTRACT FROM AUTHOR]

Indigenous yeast strains Kluyveromyces marxianus (MH6), K. marxianus (CH1), and Saccharomyces cerevisiae (C1) were screened for whey beverage production. K. marxianus (MH6) showed significantly higher (P < 0.05) fermentation efficiency (15.2%) as compare to other yeast strains. The conditions optimised for whey fermentation were 16 Brix, pH 5.5, 28 °C, and 72 h without agitation. For fermented whey beverage production, fruits viz., kinnow (Daizy), guava (Allahabad safeda), and mango (Safeda) were blended with whey at different ratios viz., 80:20, 70:30, 60:40, and 50:50. All ratios showed significant differences for biochemical and sensory analysis (P < 0.05), out of which ratios 60:40, 70:30, and 60:40 for whey kinnow, whey mango, and whey guava, respectively, were selected. To enhance the flavour of whey beverage, flavouring agents (cinnamon, cardamom, fennel seeds, and apple essence) were added. A panel of judges assessed all whey beverages on a hedonic scale basis, and cardamom whey guava beverage received the highest score of 8.16. The whey beverages were stored under refrigerated conditions after pasteurisation, and the shelf life was assessed to be 15 days. This study conferred that K. marxianus held the potential for fermented whey fruit blend beverages production and these beverages could be an alternative healthy refreshing substitute for synthetic bottled fruit beverages.

The development of innovative functional products with potential health benefits, under the concept of bio-economy, is flourishing. This study undertook an evaluation of non-dairy lactobacilli Lactiplantibacillus pentosus B329 and Lactiplantibacillus plantarum 820 as "ready to use" starter cultures. Lactic acid bacteria (LAB) cultures were evaluated for their fermentation efficiency, before and after freeze-drying, using cheese whey (CW) as a fermentation substrate and subsequent immobilization on bacteria cellulose (BC) to produce a novel biocatalyst. The biocatalyst was applied in functional sour milk production and compared with free cells via the assessment of physicochemical and microbiological properties and sensory evaluation. Evidently, LAB strains exhibited high fermentative activity before and after freeze-drying. Results of a 5-month storage stability test showed that viability was 19% enhanced by immobilization on BC, supporting the concept of "ready to use" cultures for the production of fermented beverages. Likewise, sour milk produced by the BC biocatalyst presented higher organoleptic scores, compared to the free cells case, whereas immobilization on BC enhanced probiotic viability during post-fermentation storage (4 °C, 28 days). The obtained high viability (>107 log cfu/g) demonstrated the efficacy of the proposed bioprocess for the production of functional/probiotic-rich beverages. Ultimately, this work presents a consolidated scheme that includes the advantages and the cooperative effect of probiotic LAB strains combined with a functional biopolymer (BC) towards the formulation of novel functional products that coincide with the pillars of food systems sustainability.

Black pearl Grapes are highly nutritious and one of the richest sources of polyphenols, but due to being delicate with very high loss at harvest and during distribution, is not consumed adequately. This study intended to develop functional lactic acid starter culture based fermented grapes beverage, in order to improve the quality and stability of this low pH fruit and to develop a fermented non-dairy beverage. Results showed that grapes blend was an excellent matrix for LAB growth with more than 9.38 log10 CFUml-1 of viability at the end of fermentation. LAB fermentation affectedly enhanced the total polyphenols and flavonoids content. Likewise, antioxidants capacities based on DPPH and FRAP activity were considerably increased correlating with each other, impacting the color and sensory properties of the grapes beverage. This way, the lactic acid fermentation can be considered as an appropriate tool for developing black pearl grapes based novel bio-intervention with enhanced antioxidants, polyphenols and flavonoids with anti-proliferative activity and antagonistic efficacy against recurring food borne pathogen in this postantibiotic era.

BACKGROUND The application of Pickering emulsions stabilized by food‐derived particles is of great interest, studies have focused on development of natural functional emulsifiers from agricultural byproducts. Dietary fiber (DF) has been recognizing for its excellent physiological functions. Moreover, physicochemical properties of pomelo peel DF (PDF) make it a potential emulsifier. However, pristine PDF is not suitable as emulsifier due to its compact physical structure and high hydrophobicity, which seriously limits its utilization. The objective of the study was to investigate the effects of cellulase on physicochemical properties of PDF and to illustrate the feasibility of cellulase modified PDF (MPDF) as natural functional emulsifier. RESULTS: Cellulase modification significantly improved (P < 0.05) specific surface area, water‐holding capacity/oil‐holding capacity, viscoelasticity, hydrophobicity, and pore structure while decreased crystallinity index and particle size of PDF. Emulsion could remain stable over 30 days as MPDF concentrations up to 1 wt% and oil/water ratio 3:7. The appearance stability of emulsions was not influenced by temperature (4–60 °C), pH (3.0–12.0), and ion concentration (0–200 mmol L−1) which was similar to Pickering emulsions. The mechanism of MPDF as an emulsifier was mainly attributed to the combination of Pickering effect and the three‐dimensional network. In addition, MPDF showed higher antioxidant capacity in emulsions than other classical emulsifiers. CONCLUSION: The results illustrated that MPDF has a favorable feasibility for preparation of stable Pickering‐type emulsions, which will be a practical support for application of PDF as a natural functional emulsifier and will be helpful to realize the resource utilization of DF in pomelo industries. © 2022 Society of Chemical Industry [ABSTRACT FROM AUTHOR]

Bread is one of the highest-selling food products throughout the world. Lots of demand arose from the bread producers by the consumers to convert the traditional bread into functional food. In this study, normal bread was converted to functional herbal bread by infusing it with extracts of Glycyrrhiza glabra. The functional components of the Glycyrrhiza glabra were analyzed by liquid chromatography-mass spectroscopy (LCMS). The antioxidant study revealed that the extract has high antioxidant potency. The present study also investigated the antidiabetic potency of the extract. Bread is fortified with various percentages of Glycyrrhiza glabra, such as 2, 4, and 6. The fortified bread was analyzed for various sensory and taste parameters. Biochemical assays such as the in vitro digestibility test and glycaemic index suggest that fortified bread reduces the glycaemic index. From the study, it was inferred that 6% of infused bread was found to have high potency as a functional food when compared to 2 and 4%. From the above study, it was suggested that fortified bread reduces the glycaemic index and is best suited for diabetic people and diet watchers. [ABSTRACT FROM AUTHOR]

People often consume juice to easily ingest antioxidants, which can scavenge free radicals and reduce the risk of lifestyle-related diseases. In this study, the SOD assay kit-WST method was used to evaluate the antioxidant activity of two types of functional water, alkaline electrolyzed water (AlEW) and tourmaline water (TMW), reconstituted commercially available (Tropicana) and freshly squeezed concentrated juices and the effect of functional waters on physicochemical parameters and sensory evaluation of reconstituted juices was also analyzed. The reconstituted juice exhibited the highest antioxidant activity when the electrolysis current of AlEW was 8A or the tourmaline stone treatment temperature of TMW was 75 °C. Compared with the control group (69.4%), SOD activity of the reconstituted orange juice in the 8A-AlEW (77.2%) and 75 °C-TMW (84.5%) groups increased by 7.8 and 15.1%, respectively. Furthermore, the color and pH of the functional water reconstituted juice were not significantly different from the juice before concentration, and the taste was better. In summary, functional water could enhance the antioxidant activity of concentrated juice as a formula which could provide novel ideas for the development of functional beverages with antioxidant properties.

This study analyzed the interaction between copper and functional substances in wine under different drinking amounts on alcoholic liver injury in mice. When the daily drinking amount reached 500 mL/60 kg/day (14% abv) with just ethyl alcohol, the liver aspartate aminotransferase, alanine aminotransferase, and total triglyceride levels of mice were significantly increased to 130.71 U/L, 37.45 U/L, 2.55 U/L, the total antioxidant capacity, catalase, and glutathione level decreased significantly to 1.01 U/mL, 30.20 U/mgprot, and 2.10 U/mgprot, and the liver became gradually damaged. Wine could alleviate and reduce the damage caused by ethyl alcohol well. Low concentrations of copper (0.33, 0.66 mg/L) in wine hardly caused hepatic injury in mice and only significantly improved the aspartate aminotransferase values (109.21 U/L, 127.29 U/L) of serum. Combined with the staining evidence, in the case of medium and high intragastric doses (≥500 mL/60 kg/day), 0.99 mg/L copper (the maximum allowed by China's national standards) in wine began to damage the liver, indicating that under this concentration, the damage of copper to the liver had begun to exceed the protective effect of wine's functional substances on alcoholic hepatic injury. At all experimental doses, high concentrations (1.33 mg/L, 2.00 mg/L) of copper significantly aggravated alcoholic hepatic injury in mice, indicating that high concentrations of copper have a great toxicological risk. In the future, it is necessary to further strengthen the control of copper content in wine and the inspection of market wines in order to protect the health of consumers. [ABSTRACT FROM AUTHOR]

Background: Melon Manis Terengganu (MMT) peel has a high dietary fiber content, but there is no data examining its health benefits in adults at risk of type 2 diabetes. The objective of the study was to evaluate whether consumption of MMT peel powder improves glycemic response, satiety, and food intake in adults at risk of type 2 diabetes. Methods: An open-label, randomized, placebo-controlled, crossover design trial was conducted among adults (n = 30, ages 18–59 y) at risk of type 2 diabetes. They consumed Formulation 3 (formulated MMT peel powder) [A] and control (glucose) [B] with study breakfast based on randomly assigned treatment sequences (AB, BA) established by Research Randomizer (www.randomizer.org). Capillary blood glucose and perceived satiety were determined at baseline (0 min), 30, 60, 90 and 120 min, followed by a post-intervention food intake measurement. Results: The repeated measures analysis of variance (ANOVA) revealed significant time (F = 84.37, p < 0.001, ηp2 = 0.744), condition (F = 22.89, p < 0.001, ηp2 = 0.441), and time*condition effects (F = 24.40, p < 0.001, ηp2 = 0.457) in blood glucose levels. Respondents (n = 30) who consumed Formulation 3 also had a significantly lower blood glucose 2-hour incremental area under the curve (iAUC) of 134.65 ± 44.51 mmol/L*min and maximum concentration (CMax) of 7.20 (7.10, 8.20) mmol/L with relative reduction of 26.8 and 13.3% respectively, when compared with control (p < 0.001). Besides, significantly greater perceived satiety, lower energy and fat intake as well as higher dietary fiber intake were also observed in the intervention group compared with the placebo group (p < 0.05). There were no marked side effects associated with the ingestion of the test products. Conclusions: Short-term consumption of formulated MMT peel powder may improve glycemic response, increase perceived satiety and reduce food intake in adults at risk of type 2 diabetes with the potential to be utilized as a functional beverage. Medium-to long-term clinical trial is warranted to determine whether taking this formulated MMT peel powder on a daily basis has an influence on health outcomes.

Moringa oleifera leaf powder (MOLP) is a rich source of antioxidants, protein, minerals, vitamins, and various phytochemicals and has been used to combat malnutrition in many countries. However, despite its many benefits, MOLP has low a solubility in water, necessitating the development of ways to address this issue. To improve the solubility of MOLP, solid-dispersed Moringa oleifera leaf powders (SDMOLPs) have been developed through freeze-drying, melting, microwave irradiation, and solvent evaporation methods using polyethylene glycols (PEG4000 and PEG6000) (1:1) as hydrophilic carriers. The solid dispersions were evaluated for their proximate composition using standard analytical procedures. Elemental composition was characterized using scanning electron microscopy (SEM) with energy-dispersive X-ray spectroscopy (EDS). Water absorption capacity (WAC) and water-solubility were further evaluated as functional properties. Proximate composition revealed that MOLP and SDMOLPs were rich in protein, energy, carbohydrate, ash, and fat contents. MOLP solid dispersions are a major source of minerals (Ca, Mg, Cu, and Zn), and can be used to alleviate many mineral deficiencies. All solid dispersions had significantly higher (p < 0.05) solubilities (ranging from 54 to 64%) and WAC (ranging from 468.86 to 686.37%), relative to that of pure MOLP. The increased solubility of SDMOLPs may be attributed to the hydrogen bonds and intermolecular interactions between MOLP and the hydrophilic carriers. The results indicate that the solid dispersion technique can be successfully employed to improve the solubility of MOLP. And the solid-dispersed MOLPs with enhanced functional properties may be useful as functional ingredients in foods and beverages, dietary supplements, or nutraceutical formulations.

The rising demand for health‐promoting foods has led to the search for alternative, sustainable, and multifunctional peptide sources. Unconventional though promising sources such as agro‐industrial wastes and by‐products, insects, marine, and plant RuBisCo could be the future sources of bioactive peptides. Bioactive peptides derived from various proteins are biologically active regulators that can be used as food additives to prevent oxidation and microbial spoilage. Therefore, bioactive peptides have been applied to maintain the quality and microbial safety of food products. Besides, peptides can be used as functional ingredients to treat or prevent chronic and lifestyle diseases. The present review highlights the recent findings of alternative sources of bioactive peptides, technological improvements in bioactive peptides identification and isolation, and some obstacles to the widespread application and uses of bioactive peptides. Especially, the present review discusses the application of bioactive peptides in food model systems as food additives and functional ingredients. Novelty impact statement: Recent research shows that high‐quality unconventional proteins could be the future alternatives to animal proteins to derive bioactive peptides.Bioactive peptides not only play a significant role in human health but also prevent lipid oxidation and microbial growth in foods. Hence, protein hydrolysates and peptides can replace synthetic preservatives to extend the shelf life of food products.Innovative research dedicated to the purification, isolation, and application of bioactive peptides to foods could bring multiple benefits to consumers, food processors, nutraceutical industries, and other stakeholders.

The consumption of functional beverages is rapidly increasing. The improvement in the functional properties of whey after the application of ultrasound is due to the release of bioactive peptides that have antioxidant properties, among others. Bioactive peptides with antioxidant activity have also been found in oats, stimulating the study of whey beverages formulated with oats to obtain functional products. The aim of this study was to determine the influence of ultrasound (24 kHz) at 20 °C for 15 min at 23 W and 154 W on the quality and functional properties of whey–oat (50:50 v/v) beverages and compare it with pasteurization at 65 °C for 30 min (LTLT). Non-significant effect (p > 0.05) of ultrasound intensity (23 W and 154 W) was observed on the physicochemical characteristics and the proximal composition of the whey–oat beverages. The sonicated beverages showed a greater tendency to green and yellow color (p < 0.05), higher fat content (p < 0.05), and less ash and carbohydrates (p < 0.05) than the pasteurized beverage. The antioxidant activity of the mM Trolox equivalent/mL of the sonicated beverages was higher (p < 0.05) (4.24 and 4.27 for 23 W and 54 W, respectively) compared to that of the pasteurized beverage (4.12). It is concluded that ultrasound is superior to pasteurization in improving the antioxidant activity of whey–oat beverages without having a detrimental impact on the proximal composition and physicochemical quality. Future studies should evaluate more functional parameters and determine the shelf life of sonicated whey–oat beverages. [ABSTRACT FROM AUTHOR]

Recently, new formulations of beverages with low sugar and high bioactive compound contents are being demanded because of their association with metabolic health. However, the sweeteners' influences on the bioactive compounds remain underexplored. In this sense, this work aims to evaluate the interactions between different bioactive compounds such as flavonoids, vitamin C, and sweeteners (sucrose, stevia, and sucralose) in a functional citrus–maqui beverage. For this purpose, the phytochemical behavior was studied, in model system solutions, during one-month storage at 4 °C. The results obtained corroborated previous descriptions of the interactions between these compounds. However, when studying the bioactives in the model solutions, the loss of flavanones in the citrus solution increased up to 29%, while anthocyanin losses decreased to 27%. The vitamin C losses ranged from 100% (beverage) to 46% (ascorbic acid solution). Regardless, an influence of the sweeteners was observed. Sucrose reduced the anthocyanin and flavanone losses in both model solutions and the beverage, while sucralose increased flavanone loss. Finally, all sweeteners increased vitamin C degradation (up to 75%) when compared to the model solution. In conclusion, sweeteners added to beverages should be taken into account, depending on the bioactive compounds that should be preserved during storage. [ABSTRACT FROM AUTHOR]

The use of antioxidant nutrients in beverages makes them as a functional food product. Beverage obtained from jujube (as a rich source of bioactive compounds), pea protein concentrate and whey protein isolate in the form of gel beads were surveyed in this research. Beverages were formulated with macro beads consisting of alginate, alginate-pea protein concentrate and alginate-whey protein isolate. The acidity, pH, viscosity, turbidity, Brix and sensory properties of gel ball beverage were measured. The results indicated that sodium alginate' beverage had the highest viscosity (185-263cp). A relationship was found between the samples contain protein beads and viscosity increase. The acidity (0.0832–0.1088 (gr/100 gr of citric acid)) and pH (3.55–3.75) of beverages had a reverse relation which was due to the partial release of the extract. Furthermore, the most turbidity was shown in beverage contain sodium alginate/pea protein beads (142 NTU). Universally, the formulated beverages had the best sensory characteristics. So, this antioxidant beverage can attract a wide range of consumer's opinion. Since beverages are a major part of people's consumer products, the production of novel types of them can lead consumers to use them. The use of phenolic and antioxidant compounds in delivery systems for enrichment is considered. [ABSTRACT FROM AUTHOR]

In order to solve the problem of fat metabolism and weight loss of college students, this paper puts forward a problem of the influence of sports energy drinks. Energy drink is a combination of sports drinks, energy drinks, and other special functional drinks (such as nutrient drinks with added vitamins and minerals; herbal drinks with Chinese herbal ingredients), a general term for a large category of drinks that provide specific health and nutritional functions for special groups of people. With the continuous improvement of people's consumption level and their constant attention to their own health, the consumption of energy drinks is also increasing. Energy drinks have become a new generation of drinks after carbonated drinks, drinking water, fruit and vegetable juice, and tea. At present, the total annual output of beverages in the world exceeds 300 billion liters, and functional beverages have become the fastest growing beverage varieties. Fat is the main energy supply material for endurance sports. The catabolism of fat during sports is the key link for the body to obtain energy. For the general population, abnormal fat metabolism is the main cause of obesity. In this paper, 10 healthy male and female college students without training experience were used to determine the maximum fat metabolism intensity FATmax. Based on this, the exercise prescription of maximum fat oxidation intensity for 8 weeks was formulated. The functional ability, maximum oxygen uptake, body fat percentage, quiet heart rate, blood pressure, and vital capacity before and after the experiment were measured to observe the exercise effect. The fitness effect of maximum fat metabolism intensity was studied to provide theoretical support for college students' fitness exercise. The study found that there was no significant difference between boys and girls in the maximum fat oxidation rate and FATmax, and girls' E. C. and running speed corresponding to FATmax were significantly lower than those of boys. After 8 weeks of exercise prescription exercise of maximum fat metabolism intensity, the E. C. and maximum oxygen uptake of boys and girls increased significantly; quiet heart rate, vital capacity index, and body fat percentage were significantly improved; and the changes in girls were more significant than boys. The results show that there is no gender difference in FATmax. The corresponding exercise intensity (7.22 METs for boys and 5.25 METs for girls) and running speed (9.73 km/h for boys and 8.65 km/h for girls) can be used as a reference for formulating college students' fitness exercise prescriptions. The fitness exercise prescription based on FATmax can improve cardiopulmonary function and body composition, especially for girls. FATmax can be used as a reference standard for formulating fitness exercise prescriptions. [ABSTRACT FROM AUTHOR]

The functional beverages market is one of the fastest-growing sectors of functional food production. An innovative recipe for powdered fruit and vegetable drinks fortified with lentil proteins (AGF) and stabilized with flax seed gums (FSG) was developed. The study focused on the analysis of potentially bioaccessible fractions from the produced beverages in terms of their antioxidant, antiproliferative activities and physicochemical properties. The contents of bioactive components were tailored by the incorporation of lyophilized fruits and vegetables, the FSG and the AGF. Digestion in vitro effectively released phenolics from all matrices. The highest contents of potentially bioavailable polyphenols were recorded for the AGF based beverages enriched with 5% of FSG and green-leafy vegetables (58 mg/100 mL) and those with lyophilized fruit (54 mg/100 mL). The reducing power of the beverages was mainly affected by the presence of the AGF, while the FSG and lyophilized fruit improved the chelating power. The digests applied in the concentrations mimicking physiological concentrations showed antiproliferative properties against gastric and colon adenocarcinoma—they seemed to be tailored by bioactive peptides and phenolics, respectively. The addition of the FSG improved the stability of the beverages increasing the time required for a reduction of 20% of the initial optical density by 16- and 28-times in the beverages without additives or enriched with vegetables. Both, the AGF and FSG stabilize the beverages after rehydration and are sources of bioaccessible antioxidant and anticancer components, which create their functionality. [ABSTRACT FROM AUTHOR]

As a functional beverage, selenium (Se)-enriched green tea (Se-GT) has gained increasing popularity for its superior properties in promoting health. In this study, we compared the brewing characteristics, in vitro digestion profiles, and protective effects on neurotoxicity induced through the amyloid-beta (Aβ) peptide of two typical Se-GTs (Enshi Yulu (ESYL) and Ziyang Maojian (ZYMJ), representing the typical low-Se green tea and high-Se green tea, respectively). ESYL and ZYMJ showed similar chemical component leaching properties with the different brewing methods, and the optimized brewing conditions were 5 min, 90 °C, 50 mL/g, and first brewing. The antioxidant activities of the tea infusions had the strongest positive correlation with the tea polyphenols among all of the leaching substances. The tea infusions of ESYL and ZYMJ showed similar digestive behaviors, and the tea polyphenols in the tea infusions were almost totally degraded or transferred after 150 min of dynamic digestion. Studies conducted in a cell model of Alzheimer's disease (AD) showed that the extract from the high-Se green tea was more effective for neuroprotection compared with the low-Se green tea. Overall, our results revealed the best brewing conditions and digestion behaviors of Se-GT and the great potential of Se-GT or Se-enriched green extract (Se-GTE) to be used as promising AD-preventive beverages or food ingredients.

Amaranthus hypochondriacus L. is a pseudocereal with nutritional properties. Some bioactive peptides have been identified from amaranth protein isolates. The metabolic reactions developed during seed germination have produced different functional foods. The present research aimed to develop a non‐dairy germinated amaranth‐based functional beverage fermented by Lactiplantibacillus plantarum (LP) strain using Lacticaseibacillus casei Shirota (LCS) as control. The content of betalains (BT), total phenolic compounds (TFC), antioxidant capacity (DPPH, ABTS, FRAP), color changes, and scavenging bioactive peptides were determined. BT in the original base was significantly increased after fermentation by LP and LCS (from 1.276 ± 0.030 to 2.732 ± 0.196 and 1.904 ± 0.760 mg/100 ml, respectively). TFC increased after fermentation; however, no significant differences were found between the two strains (p >.05). The fermentation did not decrease the antioxidant content of the germinated amaranth base. However, a slight increase in the antioxidant capacity was found by DPPH, ABTS, and FRAP in the beverage fermented by LP compared with the LCS one. Moreover, the peptidomic approach suggested 18 peptides with scavenging activity. Thus, a bioactive food product with antioxidant properties was obtained by germination of A. hypochondriacus and its subsequent fermentation by LP. Practical applications: Non‐dairy fermented beverages are novel carriers for probiotics and beneficial metabolites. This research evaluated the antioxidant and hypoglycemic activity of a fermented drink made with amaranth (Amaranthus hypochondriacus) and a potential probiotic strain (Lactiplantibacillus plantarum). The results led to conclude that it is possible to develop functional drinks with potential antioxidant and hypoglycemic activities and provide the biochemical basis for further research and development.

Background: Whey is the most abundant by-product of the cheese industry. It is estimated that it contains up to 55% of all nutrients of milk and therefore, it is considered a starting material for obtaining valuable products. Results: The response surface methodology was used to find the combination of temperature (between 20 and 36°C), and the content of whey powder (37.5-77% (m/m)) to maximize the concentration of kefiran, the concentration of lactic acid bacteria (LAB) and yeast in the supernatant. After validating the quadratic models of each transformed response variable, it underwent a maximization procedure to find the optimal condition obtaining two maximum spaces at the temperature range of 28.5-29.7°C and 43.3% (m/m) of whey-powder content, or 28.0-28.3°C and 71.2% (m/m) of whey-powder content. The validation experiments were carried out for the first suggested optimal solution, through three repetitions under the same optimal conditions, and it was confirmed that there is no significant difference with the values provided by the model. Conclusions: Physicochemical characteristics (protein, fat, acidity, lactose, viscosity, alcoholic content) under optimal conditions were evaluated and proved its compliance with the Ecuadorian and Andean community regulations. These results suggest that we are in the presence of a functional beverage candidate in which the contents of LAB and yeast (probiotics) and kefiran (prebiotic) were simultaneously maximized.

Over the last decade, plant-based beverages have gained popularity amongst consumers who are seeking alternative and environmentally sustainable options to traditional dairy drinks. Whilst these days there is a variety of cereal-based beverages in the market, the legume-based beverage segment is dominated by soy milk products. There is an opportunity to broaden and diversify this segment into other legumes which may offer better functionality and nutrition than soy. However, little is known about the processability, functionality, health benefits and associated health risks of legume-based milk substitutes. Therefore, this review provides an overview of the current knowledge on fundamental processing steps to convert legumes into milk-alternative beverages, what are processing challenges for different legume varieties, how to overcome these challenges and potential quality deficiencies, and what are the opportunities to maximise textural, nutritional and sensory aspects of legume-based beverages. Special attention is given to chickpea and faba beans, a legume segment largely untouched by industry so far. [ABSTRACT FROM AUTHOR]

Probiotics are becoming popular in dairy and non‐dairy matrices owing to their symbiotic effects on the human gut. However, maintaining the viability and stability of probiotics at their therapeutic level is a great challenge for manufacturers. Encapsulation technology is getting attention to maintain and target the delivery of sensitive ingredients in the food and pharmaceutical industry. Probiotics are encapsulated by using different economical biomaterials to augment their stability under stressed conditions and encapsulated by materials. Encapsulation with these biomaterials retains their recommended number in the product as well as provides a barrier against the hostile conditions in the human gastrointestinal passage. Adaptation of encapsulation technology in the dairy and beverage sector will be a way forward for the development of a different range of functional foods. The current review focuses on encapsulation, types of encapsulation material, and their suitability for the development of dairy and beverage functional foods. Practical applications: Probiotic application as functional ingredients in different food, an animal feed is increasing across the globe owing to their numerous benefits. The dairy and beverage industry is the largest in the food sector and has promising probiotic application potential. Probiotic stability and viability challenges can be addressed by encapsulation using different polymer‐based wall materials. [ABSTRACT FROM AUTHOR]

This research aimed to microencapsulate Saccharomyces boulardii using an experimental design 23 to evaluate vegan and vegetarian wall materials, rice protein, and maltodextrin in different proportions, drying temperature, and feed flow. The microcapsules were characterized by encapsulation yield, moisture content, scanning electron microscopy, Fourier transform infrared spectroscopy, thermogravimetric analysis, and survivability rate in simulated gastric solution and during storage under refrigeration. The best encapsulation yield of S. boulardii was 79.88 ± 1.35% at maltodextrin: rice protein of 25:75%, 80°C, and feed flow rate 0.75 L h−1, with survivability rate in simulated gastric solution at pH 3 of 83% in 3 h, and stability during storage in 20 days at 4 ± 1°C of 71.6%. Therefore, these wall materials are efficient to microencapsulate and preserve S. boulardii by spray‐drying, protecting the cells in gastrointestinal conditions, which may be applied in functional foods and beverages, dietary supplements, or animal feed. Novelty impact statement: Microencapsulating Saccharomyces boulardii through spray‐drying enabled its preservation and the novelty is the use of plant‐derived proteins to protect the cells as an alternative for vegetarian and vegan consumers. The resulting product can be added to functional foods and beverages, dietary supplements, or animal feed. [ABSTRACT FROM AUTHOR]

Bouea macrophylla Griff is a member of the Anacardiaceae family, which has edible fruits. Due to the high nutritional value, appealing taste, and attractive color, the fruit juice of B. macrophylla has the potential to be developed as a functional beverage. The present study was conducted to determine the phytochemical profile of B. macrophylla fruit juice using GC-MS and LCMS/MS. GC-MS analysis was performed with the Agilent Technologies 7890 Gas Chromatograph with automated sampling and tandem Agilent 5975 Mass Selective Detector and peak analysis with the Chemistation data system. LC-MS/MS QTOF analysis was performed with UPLC Waters I Class and tandem MS/MS Xevo G2S QTOF with UNIFI software. GC-MS analysis identified five compounds with a quality match of 90% and above, namely 3-pentadecylphenol (31.68%), 5,5'-(oxybis(methylene)]-bis-2-furancarboxy-aldehyde (5.67%), 5-(hydroxymethyl)-2-furancarboxy-aldehyde (23.51%), 4H-pyran-4-one, 2,3-dihydro-3,5-dihydro-6-methyl (5.00%), and n-hexadecanoic acid (4.71%). Five major compounds were identified for the first time in B. macrophylla fruit juice by LC-MS/MS analysis, i.e., (E)-hexadecyl-ferulate, digupigan A, eburicoic acid, hydroginkgolinic acid, and terminalic acid. The health benefit of some of these detected phytochemicals supports the use of juice as the main ingredient for functional food. [ABSTRACT FROM AUTHOR]

Three red color fruit juice (pomegranate (PJ), barberry (BJ), and grape juice (GJ)) and three plant extracts (cardamom essential oil (CE), ginger extract (GE), and hibiscus solution (HS)) were used for the development of different functional beverages. Organoleptic analysis was done to detect the most acceptable fruit juice blend. The physicochemical properties of the samples including total phenols, 1,1‐diphenyl‐2‐picrylhydrazyl (DPPH) inhibition percent, anthocyanin, flavonoid, and vitamin C content of optimum fruit juice blend (60% PJ/20% BJ/20% GJ) were 121.57 µg gallic acid equivalent (GAE)/ml, 80.28%, 4.03 mg/L, 64.87 mg/100 ml, and 51.10 mg/100 ml, respectively. To determine the optimum level of extracts and essential oil (GE, CE, and HS) in fruit juice blends, the mixture design method was used and 14 runs (formulations) were obtained. In all formulations, samples containing HS had the highest content of antioxidant and active components and the statistical analysis indicated that the sample containing 0.5 CE/0.5 GE/1 HS (ml/100 ml) had the optimum content of antioxidant components. Thus, the results of this study introduce a functional drink possessing high polyphenols, antioxidants, anthocyanin, and vitamin C content. [ABSTRACT FROM AUTHOR]

To study the effects of different types of commercially available drinks/beverages on neurobehavior using the model organism C. elegans, and critically review their potential health hazards. Eighteen kinds of beverages from the supermarket were randomly selected and grouped into seven categories namely functional beverage, tea beverage, plant protein beverage, fruit juice beverage, dairy beverage, carbonated beverage and coffee beverage. The pH value, specific gravity and osmotic pressure were also examined. The L4 stage N2 worms were exposed to different concentration of tested beverages (0, 62.5, 125, 250 and 500 pL/mL) for 24 h to measure the survival rate and locomotory behavior such as head thrashing, body bending as well as pharyngeal pumping. All the 18 beverages tested did not induce any visible lethal effects in the nematodes. However, exposure to different types of tested beverages exhibited different effects on the behavioral ability of C. elegans: (1) sports functional beverage and herbal tea drink accelerated the head thrashing and body bending of nematodes when compared to the control group (P < 0.05). (2) The vibration frequency of the pharyngeal pump of nematodes was significantly accelerated after treated with three plant protein beverages (almond milk, coconut milk and milk tea) and dairy products A and B (P < 0.05), and decelerated after treatment with other tested beverages. (3) Carbonated beverage significantly inhibits the head thrashing, body bending and pharyngeal pumping vibration (P < 0.05). Our results indicate that 18 kinds of popular beverages in the market have different influence on the neurobehavior in C. elegans, which may be related to their different components or properties. Further research would be required to conduct a systematic analysis of the effect of beverages by appropriate kinds, taking into consideration other endpoints such as reproduction, lifespan and molecular stress response, etc., and to elucidate the mechanism for its potential health hazards.

This work is focused on the preparation of an innovative gluten-free (GF) bread with remarkable softness and antioxidant features over time. To overcome the technological inconveniences related to the removal of gluten from bread, the kefir beverage fortified with antioxidant vegetable extracts is employed as a functional ingredient in the bread-making process. In this context, carob (Ceratonia siliqua L.) leaves represent an outstanding source of active molecules and are proposed to enrich milk-based beverages. Different extraction strategies were evaluated, and the process was improved to select a solvent (water, ethanol, or hydroalcoholic solution) and methodology (Soxhlet or ultrasound-assisted extraction) able to guarantee the best performances in terms of yield and antioxidant capacity. For kefir addition, two varieties of carob leaves (Selvatica and Amele) are employed. Functional GF bread, obtained by partially replacing the water with the enriched kefir, is prepared, and the final product is characterized in terms of its antioxidant and rheological properties. The final product shows improved compositional and technological parameters over time. [ABSTRACT FROM AUTHOR]

Plastic pollution and food waste are two global issues with much in common. Plastic containers were introduced as a practical and easy remedy to improve food preservation and reduce the risk of creating waste, but ironically, to address one problem, another has been made worse. The spread of single‐use containers has dramatically increased the amount of plastic that has to be discarded, and the most urgent task is now to find a solution to what has become part of the problem. An innovative way around it consists of promoting the valorization of food residues by turning them into novel materials for packaging. Although the results are promising, the aim of completely replacing plastics with biodegradable materials still seems far from being achieved. This review illustrates the main strategies adopted thus far to produce new bioplastic materials and composites from waste resources and focuses on the pros and cons of the food recovery process to look for the aspects that represent an obstacle to the development of the circular food economy on an industrial scale.

Research background. Anthocyanins possess valuable health-promoting activities with significant health benefits for humans. However, their instability is a limiting factor for their usage in functional foods and beverages. Experimental approach. In this work, a new method to enhance the stability of anthocyanins from mulberry fruit through acylation by using succinic acid as a selected acyl donor was explored. The Box-Behnken design of response surface methodology was applied to determine the optimized conditions for the acylation process. Results and conclusions. The highest acylation conversion rate was 79.04 % at anthocyanins to succinic acid mass ratio 1:8.96, acylation duration 3 h and temperature 50 °C. Structural analysis of acylated anthocyanins revealed that succinic acid introduces a C-O-C bond and a hydroxyl group. The thermostability and light stability of mulberry anthocyanins were significantly improved after acylation, and the antioxidant activity expressed as total reducing power and Fe2+-chelating capacity of the acylated anthocyanins was also enhanced. Novelty and scientific contribution. Succinic acid acylation provides a novel method for stabilizing mulberry anthocyanins, as evidenced by the increased stability and antioxidant ability of anthocyanins, and thus facilitates its use in the food and nutraceutical industries.

This study investigated the health-functional properties of a lactic fermented pomegranate juice (FPJ) enriched with pomegranate seed oil (FPJO) by using the fruit-origin strain Lactiplantibacillus paraplantarum CRL 2051 (FPJO-CRL2051). For this aim, the in vitro human antiplatelet aggregation effect and antioxidant activities were determined in the fermented juices while in vivo studies using high-fat-diet (HFD) C57BL/6 mice fed with a high-fat diet or pomegranate fermented juices for 8 weeks were performed. A high anti-platelet aggregation activity for FPJO-CRL2051 was determined. The formulated juice was administered to C57BL/6 HFD mice over 8 weeks, which showed a significant decrease in triglycerides, LDL-C, and pro-inflammatory cytokines levels. The FPJO-CRL2051 administration was effective in ameliorating liver damage caused by HFD, reducing fat accumulation and oxidative biomarkers, and improving the liver fatty acid profile by incorporation of conjugated fatty acids. This study shows the significance of lactic fermentation in developing novel fermented plant-based beverages with enhanced functional activities with a circular economy approach for the prevention of metabolic disorders. • Pomegranate seed oil was successfully incorporated into a fermented pomegranate juice (FPJO) • The FPJO exhibited high antiplatelet aggregation activity induced by agonists • FPJO improved the hepatic fatty acid profile and showed fat deposition-modulating effects • A novel fermented pomegranate juice with functional properties against metabolic disorders was formulated [ABSTRACT FROM AUTHOR]

The older adult population is greatly affected by malnutrition. This condition can arise from inappropriate micro and micronutrient intake, as well as due to experienced age-related changes. For instance, a significant number of older adults suffer from dysphagia. Thus, the development of foods with adequate consistency/viscosity are vital for overcome this condition. Within this framework, novel functional thickened drinks were developed and tailored for the older adult population, by using chia seed gum as the thickening agent enriched with vitamin D3-loaded solid lipid nanoparticles (SLN). Rheological properties of different thickened drinks formulated with water, semi-skimmed milk or orange juice were optimized using a central composite rotational design. Results showed that SLN delivered high vitamin D3 encapsulation efficiency with high concentration (i.e., 32 IU/mg). The different drink matrices attained distinct rheological properties, being observed that the viscosity and consistency attained with the same thickening agent concentration was higher in more complex matrices. An optimized formulation containing the tolerable upper intake level (ca. 4000 IU) was selected to study the vitamin D3 release and bioaccessibility on older adults' population using a dynamic in vitro gastrointestinal digestion system. Once more, strong matrix effects were observed and significantly affected vitamin D3 release profile, bioaccessibility and recovery during the in vitro digestion. Additionally, the drinks enrichment with SLN-VitD3 did not display a negative effect on cells viability. The development of novel functional thickened drinks tailored for older adults could provide a safer swallowing and improved vitamin D3 intake. [Display omitted] • Functional thickened drinks were produced using chia seed gum and SLN-VitD3. • Low amounts (0.35%) of chia seed gum were needed to obtain nectar-like consistency. • SLN delivered high vitamin D3 encapsulation efficiency and concentration (32 IU/mg). • The type of drink matrix significantly affected the VitD3 bioaccessibility. • Drinks enrichment with SLN-VitD3 didn't show a negative effect on cells viability.

Probiotic viability, metabolite concentrations, physicochemical parameters, and volatile compounds were characterized in Gueuze beers formulated with probiotic lactic acid bacteria (LAB) and yeast. Additionally, the sensory profile of the beers and the resistance of the probiotics to digestion were determined. The use of 2 International Bitterness Units resulted in high concentrations of probiotic LAB but a decline in probiotic yeast as pH decreased. Secondary fermentation led to the consumption of maltose, citric acid, and malic acid, and the production of lactic and propionic acids. Carbonation and storage at 4 °C had minimal impact on probiotic viability. The addition of probiotic LAB resulted in a distinct aroma profile with improved sensory characteristics. Our results demonstrate that sour beers produced with probiotic LAB and a probiotic yeast, and fermented using a two-step fermentation process, exhibited optimal physicochemical parameters, discriminant volatile compound profiles, promising sensory characteristics, and high probiotic concentrations after digestion. [Display omitted] • Lactic acid bacteria (LAB) reduced S. boulardii concentrations by lowering pH. • LAB used maltose, citric and malic acids, and produced lactic and propionic acids. • Carbonations and cold storage maintained probiotic viability after 10 days. • Probiotic LAB generated a distinct aroma profile with better sensory characteristics. • Most probiotic-enriched sour beers provided high LAB levels post-digestion.
