In the recent years, beer brewers are experimenting with using various substrates, other than traditional barley malt, water, hops, and yeast for beer production, because new adjuncts to the beer brewing can add new sensory and functional properties to this beverage. Novel potatoes with purple or red-colour flesh are a good and cheap starch source and are rich in bioactive components, which could increase the nutritive value of the produced beer. The aim of the study was to determine whether some part of barley malt can be replaced by the potatoes of purple-colour flesh and assessment of properties of such beer. Beer samples showed increased antioxidant activity, higher concentration of anthocyanins and polyphenol compounds, as well as modified composition of volatiles and lower ethanol content. Beer produced with the addition of 30% of purple potatoes showed acceptable organoleptic qualities in the sensory analysis. [ABSTRACT FROM AUTHOR]

Beverage mixtures based on pineapple (Ananas comosus) and turmeric (Curcuma longa) juice as a ready-to-drink product were developed, and their physicochemical, nutritional, and sensory properties were evaluated. Four different concentrations of turmeric juice (5%, 10%, 15%, and 20% (v/v)) were added to pineapple juice to make turmeric-fortified pineapple (TFP) juice samples. Pineapple juice without turmeric was the control. The L*, a*, b*, titratable acidity (TA), total antioxidant capacity, and %DPPH scavenging values, as well as the concentrations of the phenolic compounds curcumin and demethoxycurcumin, were significantly increased with increasing turmeric concentration. Thirty volatile compounds were detected in the mixed juice samples with turmeric. Most of the turmeric-specific compounds, including monoterpenes, sesquiterpenes and turmerones, were detected in the TFP juice samples. While the antioxidant activity of the juice samples increased with increasing turmeric concentration, the pineapple juice fortified with 10% turmeric (10%T) had the best overall quality as determined by panelists. Greater concentrations of turmeric were associated with decreased palatability due to reduced mouthfeel and sweetness and increased aftertaste and sourness. These results suggest that the 10%T juice could be developed into a commercial functional beverage with increased overall flavor and nutritional quality. [ABSTRACT FROM AUTHOR]

BACKGROUND: There are sufficient scienctific studies that support the benefit that fermented dairy products produce in those who consume them. Traditionally, cow's milk has been the most commonly used milk but there is a growing interest in the development of new dairy products, substituting cow's milk with milk from other sources, as well as in the use of microorganisms in fermentation to replace artificial preservatives or treatments that may affect the chemical and organoleptic characteristics of the product. For these reasons, the aim of the present work was to understand the behavior of five potential probiotic yeasts during the fermentation of ewe's milk and to consider their potential use as biocontrol agents. RESULTS: Saccharomyces cerevisiae 3 and Hanseniaspora osmophila 1056 provided the most promising kinetic parameters in the different salt, temperature and pH conditions tested in their technological characterization. The profiles of organic acids and volatile compounds after the fermentation period was noteworthy for contributing to the final aroma of the dairy product. Sensory analysis revealed the sour taste of all samples, and S. cerevisiae 3, Lachancea thermotolerans 1039, and H. osmophila 1056 stood out for an accentuated cheese flavor. In addition, all strains showed biocontrol activity; they reduced the mycelium of the mycotoxigenic molds. CONCLUSION: Saccharomyces cerevisiae 3 and H. osmophila 1056 could be inoculated along with bacterial starters to provide a functional fermented beverage with improved flavor. These strains also have an added value as they act as biocontrol agents. © 2022 Society of Chemical Industry. [ABSTRACT FROM AUTHOR]

High body mass index (high BMI, obesity) is a serious public health problem, and "obesity‐induced oxidative stress, inflammation, and cancer" have become modern epidemic diseases. We carried out this study to explore a functional beverage that may protect against obesity‐induced diseases. The Engleromyces goetzei Henn herbal tea is such a candidate. For this study, we carried out LC–MS analysis of E. goetzei Henn aqueous extract (EgH‐AE); then used the Caco‐2 cell line for the model cells and treated the cells with t‐BHP to form an oxidative stress system. An MTT assay was used for testing the biocompatibility and cytoprotective effects; reactive oxygen species and malondialdehyde determination was used for evaluating the antioxidative stress effect; TNF‐α and IL‐1β were used for observing the anti‐inflammatory effect, and 8‐OHdG for monitoring anticancer activity. The results of this study demonstrate that the EgH‐AE has very good biocompatibility with the Caco‐2 cell line and has good cytoprotective, antioxidant, anti‐inflammatory, and anticancer properties. It is clear that EgH‐AE, a kind of ancient herbal tea, may be used to develop a functional beverage that can be given to people with a high BMI to protect against obesity‐induced diseases.

The use of different mixtures of products and the addition of cheap raw materials such as chicory, corn and soy alter the sensory and functional characteristics of the beverage based on roasted and ground coffee beans, defects that call into question the quality of the beans imported by the producing countries in Algeria and threaten the environment through the quantities of coffee grounds produced. The objective of our study is the detection of fraud on coffee beans, the differentiation between pure coffee and coffee with sugars, the determination of the antioxidant power of some coffee powders selected in the Algerian trade, and finally to select the best consumable coffee. The physico-chemical analysis of the coffee extracts, gave an acid pH, which varies between 5.71 and 6.19, a moisture content not exceeding 5%, an ash content varying between 4.38 and 5.52%, polyphenols between 11.54 and 34.32 (mg GAE/g MS), an antiradical activity between 26.33 and 81.77% and total sugars varying between 1.156 and 4.38%. At the end of this study, the choice of consumption was made for a type of coffee with superior physico-chemical characteristics and the use of sugar content for their formula below the permitted limit, which results in a low level of regenerated acrylamide with an unpolluted environment.

Kombucha is a sweet and sour beverage made by fermenting a liquid base with a symbiotic culture of bacteria and yeast. Different tea substrates, carbohydrate sources, and additional ingredients are used to create beverages with different physical and chemical characteristics. The purpose of this work was to create a recipe and technology to study the properties of the beverage based on kombucha with a given chemical composition. The content of added functional ingredients (vitamins and inulin) in quantities comparable with reference daily intake was the specified parameter characterizing the distinctive features of the enriched beverages. For fermentation using symbiotic cultures of bacteria and yeast, a black tea infusion sweetened with sucrose was used as a substrate. The changes in the physicochemical characteristics of the fermented tea beverage base were evaluated. The dynamics of changes in pH, acidity, the content of mono- and disaccharides, ethanol, organic acids, polyphenolic compounds, and volatile organic substances were shown. The fermentation conditions were selected (pH up to 3.3 ± 0.3, at T = 25 ± 1 °C, process duration of 14 days) to obtain the beverage base. Strawberry and lime leaves were used as flavor and aroma ingredients, and vitamins with inulin were used as functional ingredients. Since the use of additional ingredients changed the finished beverage's organoleptic profile and increased its content of organic acids, the final product's physical–chemical properties, antioxidant activity, and organoleptic indicators were assessed. The content of B vitamins in the beverages ranges from 29 to 44% of RDI, and 100% of RDI for inulin, which allows it to be attributed to the category of enriched products. The DPPH inhibitory activity of the beverages was 82.0 ± 7%, and the ethanol content did not exceed 0.43%. The beverages contained a variety of organic acids: lactic (43.80 ± 4.82 mg/100 mL), acetic (205.00 ± 16.40 mg/100 mL), tartaric (2.00 ± 0.14 mg/100 mL), citric (65.10 ± 5.86 mg/100 mL), and malic (45.50 ± 6.37 mg/100 mL). The technology was developed using pilot equipment to produce fermented kombucha tea enriched with inulin and B vitamins. [ABSTRACT FROM AUTHOR]

In recent years, the development of non-dairy probiotic beverages has been stimulated due to the increase in the number of people with milk protein allergies, lactose intolerance, and those that are vegetarian and vegan eating. These functional foods have a number of health benefits, combining properties of plant matrices and probiotic effects. However, a major challenge in formulating these beverages is the limited number of adapted microbial strains with probiotic phenotype that promote desirable sensory characteristics, besides remaining viable in the final product for long periods. Therefore, this review aimed to provide an overview of the production of traditional non-dairy fermented beverages produced in the world and to show the biotechnological potential of these foods as a source of strains presenting a probiotic phenotype. In addition, the latest developments on the role of lactic acid bacteria, Bifidobacterium, and yeast species in the development of new probiotic beverages from the fermentation of fruit and cereal are discussed. Finally, some aspects related to food safety issues are shown. [ABSTRACT FROM AUTHOR]

Limitations of dairy products, such as lactose intolerance, problems related to a high cholesterol intake in diet, malabsorption, and the requirement for cold storage facilities, as well as an increasing demand for new foods and tastes, have initiated a trend in the development of non-dairy probiotic products. The possibility of producing beverages based on soy milk, sea buckthorn powder, and fermented by Bifidobacterium bifidus (Bb-12®, Bb) strain at different temperatures (30 °C and 37 °C) was examined. Strain viability, pH, and titratable acidity were measured during the fermentation period while the viability, pH, titratable acidity, and water holding capacity were determined during the storage time at 4 °C ± 1 °C within 14 days. Additionally, the survival and stability of Bb-12®, inoculated into a functional beverage when exposed to simulated gastrointestinal tract conditions, were assessed. The results obtained in this study revealed that the content of potent bioactive compounds in fermented soy milk and sea buckthorn powder depends on the processing conditions, the bacteria used in the fermentation step, and storage time.

Considering the high consumption rate of fermented milk products, the fortification of these products will increase their nutritional and functional values, thereby contributing to the protection and improvement of human health. Regarding this, algae are utilized as innovative supplementation sources that provide precious nutritional and functional components. This study aimed to evaluate 0.25% Chondrus crispus, 0.25% Chlorella vulgaris, and 0.25% of their mixture (w:w) in ayran production. To that end, the physicochemical and microbiological properties of experimental samples were investigated during the 21 days of cold storage period. Besides, the fermentation process and sensorial properties of samples were evaluated. The use of 0.25% C. vulgaris and 0.25% algae mixture shortened the fermentation time by 30 min. With the supplementation of 0.25% C. vulgaris, the protein and fat contents of ayran samples increased by 43% and 34%, respectively. The viscosities of the samples containing C. vulgaris were found to be higher. Samples containing algae maintained a higher rate of yogurt bacteria as compared to the control during the cold storage period. All sensory scores of all ayran samples decreased with the addition of algae. However, among samples containing algae, the sample containing both C. vulgaris and C. crispus had a slightly higher overall acceptability score. Overall, it can be concluded that the mixture of C. vulgaris and C. crispus or just C. vulgaris can be used as natural ingredients in the production of novel ayran with improved technological, microbiological, and nutritional properties.

Aflatoxins are considered a severe hazard, contaminate dietary products, and cause malignant alterations in liver tissues. Fermented milk (FM) is prepared using probiotic lactic acid strains. This investigation aimed to produce an integrated milk beverage, inactivating aflatoxins toxicity and biotransformation. The proximate analysis of the investigated materials and biochemical parameter changes of the in-vivo experiment were determined. Results reflected the extract's valuable content of polysaccharides and antioxidants. Nine phenolics were identified predominantly with catechin (39.67 ± 1.5 µg/g). FM-fortification is reflected by enhancement in protein (49.5 ± 2.97 g/Kg) and fiber content (1.78 ± 0.54 g/Kg) compared to the FM content. Relative rats' weight gain improved to 34.29% for the fortified-FM group close to the control; it was recorded at 16.47% for the AFM1 group. Alkaline phosphatase in AFM1 rats was 99.2 ± 1.86 U/L and decreased to 44.2 ± 0.71 U/L in the fortified-FM group (44.2 ± 0.71 U/L) to be close to the control group. Aflatoxin M1 rats exposure reflects tissue alterations and cell damage, which recorded lesser in rats treated by extract and beverage administrations. The beverage's corrective action relied on two integrated mechanisms, aflatoxin-binding to bacterial and bioactivity interaction of extract substances. This beverage stopped tissue alterations that occurred due to aflatoxins. The result supports the future production of fortified-milk beverages as a bio-shield against aflatoxin toxicity, besides their nutritional and functional properties. [ABSTRACT FROM AUTHOR]

The demand for foods containing functional ingredients has increased to a great extent as people prefer foods with health-promoting properties. The present study was aimed to prepare chhurpi- a traditional Himalayan dried cheese, supplemented with sea buckthorn leaves (SBL) having inherent nutraceutical properties. The results revealed that the addition of SBL (1.5%, 2.5% and 3.5%) to chhurpi significantly changed its color and texture. The FT-IR spectra revealed that intensity of peaks between 3400–3200 cm−1 and 1200–800 cm−1 of the enriched chhurpi samples increased significantly. The total flavonoids and total phenolics of the chhurpi samples also increased significantly from 0.05–4.63 mg catechin equivalents/g and 7.55–63.04 mg GAE/g, respectively. Enriched chhurpi showed increased anti-diabetic, anti-obesity and anti-proliferative properties. The organoleptic characteristics of enriched chhurpi samples were modified considerably and the chhurpi with 2.5% SBL was given maximum scores. HPLC analysis of SBL confirmed the presence of phenolics (gallic acid, ferulic acid and vanillic acid) and flavonoid compounds (quercetin, kaempferol and isorhamnetin). [ABSTRACT FROM AUTHOR]

Consumption of avocado (Persea americana Mill.) has increased worldwide in recent years. The avocado pulp is used, but the peel and seed are discarded as waste. Studies have shown that the seeds are rich in phytochemicals that can be utilized in food systems. The objective of this study was to evaluate the potential of Hass avocado seed as a source of polyphenols in the processing of model beverages and baked products with functional properties. The proximate analysis of the avocado seed powder was carried out. The shelf life of phenols in avocado seed powder (ASP) stored in dark, amber-colored bottle and transparent bottle was studied for six months. The seed extract was incorporated into model beverages of different pHs stored at refrigerated and ambient temperatures, and the shelf life was monitored for 20 weeks. The seed powder was incorporated into baked products at 0, 15, 30, or 50% followed by total phenolic content and sensory property analysis. Proximate composition of the seed powder for moisture, ash, protein, fiber, fat, and total carbohydrates was 14.19, 1.82, 7.05, 4.00, 13.64, and 59.30 percent, respectively. During storage of the seed powder, there was no significant difference (P > 0.05) in the phenol content under the different storage light conditions for six months. In the model beverages, lower pH levels (2.8, 3.8, and 4.8) and those stored at ambient temperatures (25°C) recorded lower phenol content than the control pH, i.e., 5.5, and those under refrigerated conditions throughout the storage period studied (20 weeks). The concentration of phenols in the baked products increased with increasing avocado seed powder. The color of all the queen cake formulations was liked very much by the sensory panel. The aroma of 0% and 15% ASP was liked very much, while the other formulations (30% and 50%) were liked moderately. The taste rating and overall acceptability decreased with an increasing avocado seed powder in the queen cake formulations. Avocado seed extracts can be incorporated to prepare functional beverages and functional baked products that are acceptable by sensory panelists. [ABSTRACT FROM AUTHOR]

Phytochemicals are natural compounds found in plants that have potential health benefits such as antioxidants, anti-inflammatory and anti-cancer properties, and immune reinforcement. Polygonum cuspidatum Sieb. et Zucc. is a source rich in resveratrol, traditionally consumed as an infusion. In this study, P. cuspidatum root extraction conditions were optimized to increase antioxidant capacity (DPPH, ABTS+), extraction yield, resveratrol concentration, and total polyphenolic compounds (TPC) via ultrasonic-assisted extraction using a Box–Behnken design (BBD). The biological activities of the optimized extract and the infusion were compared. The optimized extract was obtained using a solvent/root powder ratio of 4, 60% ethanol concentration, and 60% ultrasonic power. The optimized extract showed higher biological activities than the infusion. The optimized extract contained 16.6 mg mL−1 resveratrol, high antioxidant activities (135.1 µg TE mL−1 for DPPH, and 230.4 µg TE mL−1 for ABTS+), TPC (33.2 mg GAE mL−1), and extraction yield of 12.4%. The EC50 value (effective concentration 50) of the optimized extract was 0.194 µg mL−1, which revealed high cytotoxic activity against the Caco-2 cell line. The optimized extract could be used to develop functional beverages with high antioxidant capacity, antioxidants for edible oils, functional foods, and cosmetics. [ABSTRACT FROM AUTHOR]

This study aimed to develop potentially synbiotic yellow mombin (Spondias mombin L.) beverages added with fructooligosaccharides and Lactiplantibacillus plantarum NRRL B-4496. Six formulations of yellow mombin beverages were prepared to measure the influence of fermentation and pH, which was adjustment to 4.5 for stability and quality parameters. Formulations were evaluated for probiotic survival, pH, titratable acidity, total phenolic compounds (TPC), and antioxidant activity for 28 days at 4 °C. Additionally, the proximate composition, color, sensory aspects, and survival to simulated gastrointestinal conditions were studied. At 21 days of storage, the viability of L. plantarum was 9 CFU/mL for the fermented symbiotic (SYNf) and non-fermented symbiotic with adjusted pH (SYNa) formulations. In addition, the fermented synbiotic with an adjusted pH beverage (SYNfA) showed a count of 8.2 log CFU/mL at 28 days. The formulations showed a high TPC (234–431 mg GAE/L), antioxidant activity (48–75 µM trolox), and a potential use as low-calorie beverages. The SYNf formulation showed an acceptability index higher than 70% and a high purchase intent. The SYNf and SYNa formulations maintained suitable probiotic counts after exposure to the simulated gastrointestinal digestion. Therefore, it was possible to develop a new potentially synbiotic yellow mombin beverage with a high sensory acceptance, supplying the market with a new functional food alternative.

Traditional kombucha is a functional tea-based drink that has gained attention as a low or non-alcoholic beverage. The fermentation is conducted by a community of different microorganisms, collectively called SCOBY (Symbiotic Culture of Bacteria and Yeast) and typically consists of different acetic acid bacteria and fermenting yeast, and in some cases lactic acid bacteria that would convert the sugars into organic acids—mostly acetic acid. In this study, the effect of including a Pichia kluyveri starter culture in a kombucha fermentation was investigated. P. kluyveri additions led to a quicker accumulation of acetic acid along with the production of several acetate esters including isoamyl acetate and 2-phenethyl acetate. A subsequent tasting also noted a significant increase in the fruitiness of the kombucha. The significant contribution to the aroma content shows the promise of this yeast in future microbial formulations for kombucha fermentations. [ABSTRACT FROM AUTHOR]

Biorefinery of onion vinegar (OV) is attractive as a method for producing functional foods from onions or onion by-products. In this study, a two-stage fermentation of OV using Saccharomyces cerevisiae ATCC9763 and Acetobacter pasteurianus CICC20001 was carried out at 28 °C, the titratable acidity reached 4.01%, and the YA/E was 69.64% at 72 h. Based on this, semi-continuous fermentation was performed, proceeded to charge-discharge consisting of three cycles, and the yield, productivity, and specific production rate were 76.71%, 17.73 g/(L·d), and 20.51 h−1, respectively, which was higher than fed-batch fermentation. The in vivo antioxidant experiments showed that OV significantly increased GSH-Px, SOD, and CAT enzyme activities of Caenorhabditis elegans at 271.57, 129.26, and 314.68%, respectively. Nutritional analysis revealed that the total flavonoids and polyphenols were 3.01 mg/mL and 976.76 µg/mL, respectively. It was also shown that the acetic acid to total organic acid (A/T) ratio of OV was 79.02%, and the total free amino acid content was 262.30 mg/100 mL, 1.78–7.44 times higher than other fruit vinegar. The OV prepared in this study showed higher quality than the commercial vinegar. [ABSTRACT FROM AUTHOR]

Summary: The development of synbiotic vegan drinks expands the probiotic food options on the market as an alternative to dairy products and with no added sugars. This study aimed to investigate the impact of fermentation and inulin addition in mixed carrot‐orange juice with Lactiplantibacillus plantarum (LP) on the sensory profile, consumer acceptance and functional stability. The results demonstrated that all fermented juices had high antioxidant capacity (AOC) and were a rich source of bioactive compounds such as β‐carotene and phenolics. However, only the β‐carotene showed a high correlation with the AOC. Inulin could improve LP survival, remaining at high concentration during the 21 days of storage. Only fermented juices with 2% inulin showed a positive correlation with sweet taste and had the best impact on sensorial properties. Fermentation with LP and inulin addition could contribute to the improvement of orange flavour and taste. Penalty analysis showed that the control‐unfermented juices were the samples with a clear need for improvement with respect to the fermented ones. Therefore, carrot‐orange juices represent a promising vegan food matrix for probiotic delivery. [ABSTRACT FROM AUTHOR]

Since certain constituents are not naturally present in pure fruit juices, incorporating herbal extracts can provide specific sensory properties to the beverages and improve their biopotential. In our previous research, it was found that sage (Salvia officinalis L.), wild thyme (Thymus serpyllum L.), and combinations of their extracts had the highest total phenolic content and a unique composition of volatile compounds, which can contribute to the aromatic and antioxidant qualities of functional products. Therefore, this research aimed to investigate the potential of sage and wild thyme extracts, as well as their mixture (wild thyme:sage at 3:1, v/v), to enrich fruit juices (apple, pineapple, and orange). Obtained beverages were evaluated for sensory properties as well as phenolic and headspace composition (UPLC-MS/MS and HS-SPME/GC-MS analysis) and antioxidant capacity (ORAC assay). The incorporation of wild thyme extract in pineapple juice provided the most harmonious flavor and the highest content of volatile compounds (on PDMS/DVB fiber). The orange juice formulations were the most enriched with phenolic and volatile compounds (on DVB/CAR/PDMS fibers). The highest antioxidant capacity was observed in the formulation with orange juice and sage extract (22,925.39 ± 358.43 µM TE). This study demonstrated that enriching fruit juices with sage and wild thyme extracts could create functional beverages with improved sensory and health-promoting properties, providing valuable insights for the food and beverage industry to meet the growing demand of health-conscious consumers for natural and functional products.

Although people's perception of fruits and vegetables is green, healthy and nutritious, the consumption of fruits and vegetables for most people around world still does not meet the WHO's recommendations for a healthy diet. Functional foods and beverages containing functional ingredients with health-improving properties, are gaining increasing popularity among consumers and the food industry. Either hydrous or dried fruit and vegetables formulated into beverages can promote the daily intake and is a splendid delivery approach for nutrients and bioactive compounds to human body. Drying is the good method to preserve fruit and vegetables characterized by high moisture content and perishability. However conventional drying processes are strongly associated with high temperature, which is detrimental to their nutritional and sensory qualities. This work aims to review low temperature drying technologies for fruits and vegetables to better maintain the qualities and expand their application in functional beverages. [ABSTRACT FROM AUTHOR]

Background: The concern about consuming healthy foods has increased in recent years. Not only are they expected to comply with essential feeding functions, but they also provide health benefits. Probiotics are one of the main functional components expected to be present in functional foods and beverages. They provide many health benefits and stand out due to their metabolic capacities and adaptability to different habitats. In addition, Quinoa seeds contain valuable quantities of quality protein and nutritional values of carbohydrates, proteins, fats, fibers, and mineral substances for which they are considered an ideal dietary alternative. Objectives: This research aimed to elaborate on a probiotic quinoa beverage, which combines the effect of enzymatic hydrolysis of the starches obtained from its seeds with lactic acid fermentation using probiotic cultures, seeking to enhance its nutritional properties and converting it into a functional beverage. Methods: For this, fermentations were carried out in three different concentrations of probiotic cultures (inoculum): 10%, 5%, 1%, and three other different fermentation times: 8, 10, and 12 hours. pH, Total titrable acidity expressed as lactic acid (%), reducing sugars, and soluble solids were measured. After that, the beverage was formulated with honey, carob, preservatives, and mango flavoring. Results: Statistical analysis indicated optimal conditions were achieved with 10% probiotic cultures and 10 hours of fermentation. The microbiological analysis confirmed the presence of probiotic microorganisms at a concentration of 108 CFU/mL. Proximal analysis indicated that the composition contained 84.6 Kcal, 19.3 g of carbohydrates, and 1.4 g of protein per 100 g of beverage. Conclusions: The probiotic quinoa beverage was produced and can be considered in the group of plant-based foods, as well as a functional beverage, since the probiotic cultures it contains contribute to maintaining the intestinal microbiota and prevent the onset of chronic diseases.

Artificial preservatives have long been used by the meat industry to control chemical, microbial, and enzymatic degradation activities; and to enhance the shelf life, safety, and quality of meat products. However, the reported toxicological and carcinogenic effects of these additives; and consumer preferences towards natural or plant-based food preservatives have insisted the meat industry to look for their natural alternatives. Rosemary is one of the most promising, versatile, and most studied natural preservatives that have been reported to reduce the rate of oxidative reactions and microbial growth in meat products, thereby extending their shelf life. The promising biological and functional characteristics of rosemary are due to the presence of bioactive compounds like phenolic diterpenes, flavonoids, and triterpenes. These bioactives are well renowned for their antioxidant, antimicrobial, anti-inflammatory, anticancer, and neuroprotective properties. This review highlights the use of rosemary in a diverse range of meat products, including in their packaging. Encapsulation of rosemary and its mechanism of action have also been discussed.

This study was planned to investigate the effect of atmospheric cold plasma (CP) treatment at different power levels (20–30 kV) for 10–20 min on physicochemical, technofunctional, and intermolecular changes of pearl millet flour (PMF). It was observed that exposure to plasma significantly modified the sample's proximate, antinutritional, functional, thermal, rheological, and morphological properties. A concomitant (p < 0.05) decreases in antinutritional factors (tannin and phytic acid) was noticed in CP‐treated PMF compared to the control sample. Maximum reduction in tannin and phytic acid was observed at 30 kV for 20 min‐treated PMF. However, scanning electron microscopy revealed significant changes in flour starch granular structure, while decreases in relative crystallinity were also observed in CP‐treated samples from 23.45% to 19.31%. In addition, an increase in water absorption capacity (1.32–1.62 g/g), oil absorption capacity (1.11–1.31 g/g), emulsifying capacity (EC; 86.58%–91.25%) and foaming capacity (FC; 10.67–12.84%), as well as a decrease in pH (7.83–6.97) were found at 30 kV for 20 min. Apart from this, high intensity CP‐treated samples showed shear thinning behavior. At the same time, the power–law model was more appropriate for determine the flow behavior index (n) and consistency coefficient (k). On the other hand, CP‐treated samples exhibit higher storage modulus values (G′), indicating an elastic response. Based on the observations, the 30 kV‐20 min‐treated sample could be used for product formulation, contains lower antinutritional factors and retaining the nutritional components and functional properties. Practical applications: This work has identified that exposure to cold plasma improved the physicochemical, rheological, thermal, and functional properties of pearl millet flour with considerably reducing its antinutritional content, which can be helpful for various food industries. This possibly will encourage its application in the development of various food products, (like cookies, biscuits, bread, beverages, etc.) chiefly as a functional food ingredient.

There are millions of built structures existing today in thousands of rivers. While these structures provide important services to society, e.g., power, transportation, and water for drinking and irrigation, the structures are not without consequences for provisioning the whole of a rivers' goods and services. A major issue for these structures is their creation of barriers for fish passage. While most provide some form of fish passage, the solutions are restricted to economically important species and barriers in isolation. We are slowly accepting that there are broader ecological consequences of barriers and more holistic approaches are emerging for the planning and managing created barriers in river ecosystems. We develop a holistic and adaptive, fish passage decision-making framework that uses key science questions to inform and support the development of successful fish passage management plans for a barrier and the river ecosystem. The framework builds from the biological needs of fish for functional passage, which can then support the complex social and economic considerations that are entwined in a comprehensive management plan. The framework uses a multi-species, ecosystem focus, embraces uncertainty, and embraces an adaptive approach. We recognize this approach advocates for a paradigm shift in fish passage decision making and management, but cracks in the old paradigm are emerging, and it is imperative that operators, regulators, rightsholders, stakeholders, and science keep working together to build this new paradigm that embraces a whole ecosystem approach.

Kombucha is a functional beverage obtained through fermentation of sweetened Camellia sinensis infusion by a symbiotic culture of bacteria and yeasts that exerts many beneficial biological effects, mostly related to its antioxidant and anti-inflammatory effects. Alternative raw materials have been used to create new kombucha or kombucha-like products. Coffee is the most important food commodity worldwide and generates large amounts of by-products during harvest and post-harvest processing. The main coffee by-product is the dried fruit skin and pulp, popularly known as cascara. To date, no studies have evaluated the potential bioactivity of coffee cascara kombucha. In this study, we aimed to measure and compare the effects of infusions and kombuchas made with arabica coffee cascaras (n = 2) and black tea leaves (n = 1), fermented for 0, 3, 6, and 9 days on the intracellular production of Reactive Oxygen Species (ROS) and Nitric Oxide (NO) in model cells. Oxidative stress was induced in HK-2 cells with indoxyl sulfate (IS) and high glucose (G). Inflammation was induced with lipopolysaccharide (LPS) in RAW 264.7 macrophage. The contents of phenolic compounds, caffeine, and other physicochemical parameters were evaluated. To the best of our knowledge, this is the first study providing information on the bioactive profile and on the potential biological effects of coffee cascara kombucha. Fermentation caused the release of bound phenolic compounds from the infusions, especially total chlorogenic acids, with an average increase from 5.4 to 10.7 mg/100 mL (98%) and 2.6–3.4 mg/100 mL (30%) in coffee cascara and black tea kombucha, respectively, up to day 9. All evaluated beverages reduced (p < 0.0001) similarly the intracellular ROS (41% reduction, on average) and uric acid (10–55%) concentrations in HK-2 model cells, reversing the induced oxidative stress. All beverages also reduced (p < 0.0001, 81–90%) NO formation in LPS-induced macrophages, exhibiting an anti-inflammatory effect. These potential health benefits may be mostly attributed to polyphenols and caffeine, whose contents were comparable in all beverages. Coffee cascara showed similar potential to C. sinensis to produce healthy beverages and support sustainable coffee production. [ABSTRACT FROM AUTHOR]

The use of green technologies such as ultrasound and natural deep eutectic solvents (NADES) for revalorisation of food and agricultural by-products represents a sustainable way to tackle waste and promote a healthier environment while delivering much-needed functional food ingredients for an increasingly unhealthy population. The processing of persimmon (Diospyros kaki Thunb.) generates large amounts of by-products rich in fibre-bound bioactive phytochemicals. This paper assessed the extractability of bioactive compounds through NADES and the functional properties of the persimmon polysaccharide-rich by-products to evaluate their suitability to be used as functional ingredients in commercial beverages. Although higher amounts of carotenoids and polyphenols were extracted after eutectic treatment vs. conventional extraction (p < 0.05), the fibre-bound bioactives remained abundant (p < 0.001) in the resulting persimmon pulp by-product (PPBP) and persimmon pulp dietary fibre (PPDF), showing also a strong antioxidant activity (DPPH•, ABTS•+ assays) and an improved digestibility and fibre fermentability. The main structural components of PPBP and PPDF are cellulose, hemicellulose and pectin. PPDF-added dairy-based drink showed more than 50% of preference over the control among panellists and similar acceptability scores to the commercial ones. Persimmon pulp by-products represent sustainable source of dietary fibre and bioactives and are suitable candidates to develop functional ingredients for food industry applications.

Cannabidiol (CBD), the most predominant cannabinoid, may cause addiction and liver damage. In this study, we synthesized a CBD hapten containing the carboxyl group of the spacer arm by derivatizing CBD. A highly specific and sensitive monoclonal antibody (mAb) was prepared with a half-maximal inhibitory concentration of 2.03 ng mL−1 and a limit of detection of 0.32 ng mL−1. MAb was highly specific for CBD. We developed an immunochromatographic assay (ICA) for the detection of CBD in functional beverages with a visible limit of detection of 100 ng mL−1 and a cut-off of 1000 ng mL−1. Compared with HPLC, ICA is more efficient and accurate and can be used for the rapid on-site detection of CBD in samples. [ABSTRACT FROM AUTHOR]

The crucial role of dyslipidaemia, especially hypercholesterolemia, in the development of atherosclerosis-related cardiovascular diseases has been extensively documented in genetic, pathologic, observational and intervention studies. The European guidelines for dyslipidaemia management include the possible use of lipid-lowering nutraceuticals to support a relatively large number of natural compounds. In this context, we have conducted a study to investigate whether dietary supplementation with a functional nutraceutical beverage, containing a standardized polyphenolic fraction from fruit, red yeast rice, phytosterols, and berberine complexed with β-cyclodextrin, could positively affect serum lipid concentration in 14 subjects with hypercholesterolemia. After 12 weeks of treatment, dietary supplementation with this nutraceutical combination was associated with significant improvements in total cholesterol, low-density lipoprotein cholesterol, non-high-density lipoprotein cholesterol (non-HDL-C) and apolipoprotein B, compared to baseline. Compliance was excellent and no adverse effects were reported. In conclusion, this study demonstrates that 100 mL of a functional beverage containing lipid-lowering nutraceuticals safely leads to significant improvements in serum lipids in subjects with moderate hypercholesterolemia. Future research is needed to unravel the role that the polyphenols contained in fruit extracts play in the reduction of cholesterolemia and in cardiovascular disease prevention.

In previous studies, the Argentinean native plants called Zuccagnia punctata (jarilla, pus pus, lata) and Solanum betaceum (chilto, tree tomato) were reported as new natural sources of antioxidant compounds, mainly chalcones, anthocyanins and rosmarinic acid derivates. The present study deals with the production of antioxidant beverages of Z. punctata (Zp) extract and chilto juice with honey as sweetener. A Zp extract and red chilto juice were obtained according to Food Code and characterized. The beverages were formulated by using maltodextrin (MD) with two dextrose equivalents (DE), 10 and 15, and then spray-dried at an inlet air temperature of 130 °C. The physicochemical, microscopical, phytochemical and functional characteristics of the powders were surveyed. The experiments carried out showed good physical properties for both formulations showing high water solubility with adequate features for handling, transport and storage. The chromatic parameters of both powdered beverages indicate orange–pink tones regardless of the wall material used. The total polyphenol and flavonoid content in the beverages were kept after spray-drying (92 and 100%, respectively). The anthocyanins were less stable under drying conditions (yield 58%). Both powdered beverages showed high scavenger capacity on ABTS•+, HO• and H2O2 (SC50 between 3.29 to 41.05 µg GAE/mL) and were able to inhibit xanthine oxidase (XOD) activity (CI50 between 91.35 and 114.43 µg GAE/mL). The beverages were neither toxic nor mutagenic in the concentration range with biological activity. The results obtained in the present work scientifically support the use of the powdered beverages of Argentinean native plants as antioxidant. [ABSTRACT FROM AUTHOR]

Waste generated from the agro-food industry represents a concerning environmental, social and economic issue. The Food and Agriculture Organization of the United Nations defines food waste as all food that decreases in quantity or quality to the extent that it is thrown out by food service providers and consumers. The FAO reports that 17% of worldwide food production may be wasted. Food waste may include fresh products, food close to the expiration date discarded by retailers and food products from household kitchens and eating establishments. However, food waste offers different possibilities to extract functional ingredients from different sources, such as dairy, cereals, fruits, vegetables, fibers, oils, dye and bioactive compounds. The optimization of agro-food waste as an ingredient will help in the development and innovation of food products to generate functional food and beverages to prevent and treat several diseases in consumers.

Beyond this feature, the present review firstly describes scientific studies on the antimicrobial and antioxidant activities of several Ocimum species. Secondly, the use of Ocimum plants as ingredients for food preservation, such as meat, fish and dairy products was covered. Thirdly, the phytochemical composition has been reviewed to reinforce further standardization to be Ocimum plants used as preservatives. Finally, other pharmacological properties (cardioprotective activity, anti-diabetic activity, hepato-renal protective activity, anticancer activity) are also reviewed. Overall, these plants can serve to promote food preservatives and functional ingredients, but there are still some challenges to be overcome as this review points out. [ABSTRACT FROM AUTHOR]

Microencapsulation is an up-and-coming technology for maintaining the viability of probiotics. However, the effect of core-to-wall ratios and ratios of polysaccharides on the protection of the Lactiplantibacillus plantarum 299v strain has not been deeply discussed. Lyophilization of the Lp. plantarum 299v strain was conducted, and different core-to-wall ratios and ratios of maltodextrin (MD) and resistant starch (RS) were applied. Results demonstrated that the content of MD and RS had an influence on the yield and bulk density in both core-to-wall ratios (1:1 and 1:1.5). In addition, samples coated with a core-to-wall ratio of 1:1.5 had significantly higher viability than those coated with a core-to-wall ratio of 1:1. Moreover, samples coated with core-to-wall ratios of 1:1 and MD:RS 1:1, as well as core-to-wall ratios of 1:1.5 and MD:RS 3:1, had the highest cell number after simulated gastric fluid and simulated intestinal fluid testing, respectively. Furthermore, the optimal formulation for the application of microencapsulated Lp. plantarum 299v in apple juice (serving as a functional beverage) is listed as follows: core-to-wall ratios of 1:1 and MD:RS 1:1, with the fortification method, and stored at 4 °C. After 11 weeks of storage, the cell count was 8.28 log (CFU/mL). This study provided a strategy for Lp. plantarum 299v to achieve high viability in long-term storage and provides an application in functional apple beverages. [ABSTRACT FROM AUTHOR]

This study examined the effects of adding herbs, spices, and fruits into fermented Olympus Mountain tea (Sideritis scardica) kombucha using thyme honey as a sweetener. This study evaluated how these additions affected the tea’s physical, chemical, and functional characteristics. Two different enrichments were proposed: a “Golden Mountain tea and honey Kombucha” (KG) with fresh ginger, turmeric powder, and lemon zest and juice and a “Red Mountain tea and honey Kombucha” (KR) with dried hibiscus calyces, rose petals, and lavender blossoms. In KR, the levels of vitamin C increased from 33.2 ± 2.7 to 48.4 ± 4.5. Additionally, the levels of calcium increased from 31.0 ± 1.2 to 55.7 ± 1.2, while the levels of potassium practically doubled from 64.7 ± 0.6 to 115.7 ± 2.5. An increased potassium concentration was observed in KG, and ionic iron was found for the first time after both enrichments. The total phenolic and flavonoid contents, along with antioxidant capacity, as assessed by the ABTS and DPPH methods, were found to be substantially enhanced in KR. In KG, the total phenolic content increased, together with antioxidant activity, as assessed by ABTS. Enrichment with hibiscus calyces, rose petals, and lavender blossoms significantly increased inhibitory effects against α-amylase, α-glucosidase, acetylcholinesterase, and butyrylcholinesterase. On the other hand, enrichment with ginger, turmeric, and lemon zest and juice decreased inhibitory effects against α-glucosidase and increased those against α-amylase, acetylcholinesterase, and butyrylcholinesterase. KR had the strongest enzyme-inhibiting activity, with its α-glucosidase-inhibiting activity increased by approximately 18 times. Therefore, enrichment with selected herbs, spices, and fruits can transform fermented Olympus Mountain tea kombucha sweetened with honey into a novel beverage with enhanced functional properties.

Yarrowia lipolytica is a non-conventional non-pathogenic, generally regarded as safe yeast. It has been isolated from a wide variety of places, from foodstuffs like beer, cheese and sausages to beetle guts and human mouths. It is strictly aerobic and Crabtree-negative. Y. lipolytica harbours various biochemical and physiological traits that make it relevant for biotechnological and food-related applications. Until recently, the application and effect of Y. lipolytica on lipid-containing foodstuff, that is, meat and dairy, have been researched and discussed meticulously. The yeasts’ potential as a synthesiser of several high-value food ingredients, such as organic acids, aromas, and emulsifiers from a range of diverse substrates, from ethanol to olive oil waste, is of interest in a biorefinery context. Interestingly the use of Y. lipolytica as a starter culture in foodstuffs beyond meat and dairy is minimal, despite its ability to synthesise interesting aromas and organic acids that could increase the organoleptic quality of fermented beverages. Besides the indulgence factor, Y. lipolytica synthesises a wide range of functional and bioactive compounds that can act as active ingredients in functional beverages, adding to its potential in producing novel beverages.
