Special Issue Information

Dear Colleagues,

The original idea of health-promoting foods and beverages is several millennia old, and many different cultures worldwide have practiced the development of beverages with nutraceutical properties. Nowadays, there is an increasing demand, not only for foods as ‘whole foods’, but also for the use of individual and isolated ingredients in the form of purified compounds. In Western society, use of functional beverages is a relatively new concept, and it is predominately orientated towards the fortification/addition of ingredients that can exhibit potential beneficial health effects. Several studies have already identified (or are still under investigation) the beneficial uses of these beverages and have influenced the beverages industry towards mass-scale production.

Therefore, the aim of this Special Issue, “Functional Beverages, from Idea to Functionality” is to compile recent high-quality research manuscripts (letters to the editor, original research and review papers) on functional beverages, covering topics from the generation of ideas, stability studies to animal and human trials, as well as any other functional applications of these types of beverages. This Special Issue is expected to provide up-to-date information on all aspects of research in functional beverages with a main emphasis on potential health benefits.

Prickly Pear (PP) is often overlooked due to its’ short shelf-life. Juicing may improve marketability but often affects quality, thereby warranting investigation. Purple PP (whole (WF) and flesh (FF)) was juiced using blenders; stick (SB) and jug (JB); and juicers; commercial (CJ) and [...] Read more.
Prickly Pear (PP) is often overlooked due to its’ short shelf-life. Juicing may improve marketability but often affects quality, thereby warranting investigation. Purple PP (whole (WF) and flesh (FF)) was juiced using blenders; stick (SB) and jug (JB); and juicers; commercial (CJ) and cold-pressed (CP). Juices and methanolic (70%) pomace extracts were analysed for; bioactives; Total Phenolic (TPC; µgGAE/mL), Flavonoid (TFC; µgCE/mL) and Betalain Content (TBC; mg/100 g; Betacyanin; BE; Betaxanthin; IE); and antioxidant characteristics; DPPH, FRAP (µMTE) and vitamin C (mgAAE/mL). Juicing techniques had effects on phytochemicals in; juice: TPC (WF/FF; p = 0.022–0.025), TFC (FF; p = 0.034), Betacyanin (WF/FF; p = 0.029–0.026), FRAP (WF/FF; p = 0.016–0.024) and Vitamin C (WF/FF; p = 0.015–0.016); and pomace: TPC (WF/FF; p = 0.015), TBC (FF; p = 0.034), Betacyanin (FF; p = 0.047), Betaxanthin (FF; p = 0.017), DPPH (WF/FF; p = 0.016–0.024), FRAP (WF/FF; p = 0.015–0.023) and Vitamin C (WF/FF; p = 0.016–0.022). Processing-style (blend/juice) affected; TPC, DPPH and FRAP in juice and pomace. Overall, fruit-preparation (WF/FF) had minimal effects. Additionally, correlations existed between; juice TFC and TBC (p = 0.001; τ = −0.044); TBC and vitamin C (p = 0.001; τ = −0.637); pomace TPC and DPPH (p = 0.003; τ = 0.440), TPC and vitamin C (p = 0.011; τ = 0.440); and TFC and FRAP (p = 0.001; τ = 0.519). The best methods overall for juice were SB (FRAP), JB (TPC, TBC), CJ (TFC) and CP (DPPH, VitC); and for pomace extracts; SB(FRAP), JB (TPC, VitC), CJ(TFC), and CP (TBC, DPPH). Full article

High-fat-diet (HFD) has been related to metabolic and cardiovascular diseases. Consumption of grapes and their byproducts containing phenolic compounds has been reported due to the benefits they produce for human health. The purpose of this study was to investigate the antioxidant and protective effect of chronic intake of purple grape juice on certain biochemical and physiological changes promoted by the consumption of HFD. Forty male rats were randomly divided into four groups to receive standard or HFD diet and/or conventional (CGJ) or organic grape juice (OGJ) for three months. Dietary intake, body weight gain, cardiometabolic parameters, and serum lipoperoxidation were investigated. Results showed that consumption of CGJ and OGJ changed the pattern of food and drink intake of the animals. There was a reduction in the body weight of animals that consumed grape juices and an increase in the weight gain in HFD and OGJ rats. HFD increased abdominal fat and the abdominal fat/weight ratio, and both grape juices prevented these modifications. HFD increased hepatic enzymes levels (aminotransferase (AST) and gamma-glutamyl transpeptidase (GGT)) and reduced urea. Purple grape juices prevented some of these changes. HFD enhanced lipid peroxidation (thiobarbituric acid reactive substances (TBARS)) in serum and CGJ and OGJ prevented this increase. The consumption of purple grape juice has the potential to prevent and ameliorate most of the alterations provoked by HFD, therefore regular intake of grape products could promote beneficial effects.

The demand for antioxidant-rich beverages is steadily expanding. At the same time, the possibility of manufacturing products with reduced sugar content, sweetened with natural ingredients, represents a decisive aspect of obtaining quality products with health benefits. Stevia rebaudiana Bertoni (stevia) is a natural sweetener that can help to control caloric intake and is also a good source of antioxidant compounds. The present study was designed to assess the feasibility of producing high-quality berry juices sweetened with dry-grinded stevia leaves or their crude extract. The effect of the stevia supplementation on the antioxidant activities of raspberry juices was determined at two different production steps by means of the Folin–Ciocalteu, the oxygen radical absorbance capacity (ORAC), and the cellular antioxidant activity (CAA) assays. The addition of stevia significantly increased the antioxidant activity of the juices and resulted in significantly higher ascorbic acid and total phenolic content. A positive correlation was observed between ORAC, CAA, and total phenolic values. These findings show that supplementation with stevia not only promotes a healthy diet by reducing sugar intake but may also enhance the antioxidant potential of the beverage. Full article

Menthol mouth-swilling has been shown to improve performance across differing exercise modalities, yet no work has been conducted to ascertain the preferred concentration of menthol within a swill. Colour has also been shown to influence psychophysiological outcomes, and may influence the efficacy of ergogenic aids. We conducted two experiments: one to ascertain preferred menthol concentration (0.005–0.105% menthol), the second to assess colour preference (Light Blue, Dark Blue, Light Green, Dark Green, Red). Participants rated swills for Smell, Taste, Freshness, Mouth Feel and Irritation (plus Appearance in the second trial) via 15 cm Visual Analogue Scales (VAS), having swilled and expectorated 25 mL of fluid. Both trials employed a crossover design, with tasting order assigned by Latin squares. Differences were assessed for statistical significance (p < 0.05) using one-way repeated measures ANOVAs. Standardised mean differences ±90% confidence intervals were calculated to assess the magnitude of any observed differences. No significant differences were found between concentrations for total VAS score, but higher concentrations demonstrated a greater number of small effects. Similarly, no significant differences between colours were found. Small effects were found when Light Green was compared to Dark Green and Red. Effects were trivial when Light Green was compared to Light Blue (0.05 ± 0.20) and Dark Blue (0.19 ± 0.32). We recommend athletes employ a Light Green or Light Blue 0.1% menthol mouth-swill.

This study aimed to develop a process for the development of ready to serve (RTS) beverages from enzyme liquefied (pectinase) Cape gooseberry juice with additives and preservatives. Storage stability of the RTS beverage at both refrigerated temperature (LT: 4 ± 1 °C) and room temperature (RT: 27 ± 2 °C) were evaluated for 90 days for microbial, sensorial and physicochemical quality parameters. The stability of RTS beverage stored at LT (4 ± 1 °C) was excellent with a retention of the primary quality attributes ascorbic acid (15.44 mg/100 mL), total phenolic content (15.50 mg GAE/100 mL), total carotene (1.07 mg/100 mL), β-carotene (0.78 mg/100 mL), high viscosity (30.29 cp), and with high sensory scores of the product (8.3) up to 90 days as compared to the overall acceptability (6.5) of RT stored RTS for 60 days. Additionally, both the LT and RT stored RTS beverages had microbial counts within the permissible limits. Therefore, both beverages were safe to consume at the end of storage duration. In conclusion, the RTS beverage developed from Cape gooseberry could be served as functional health drink alternative to synthetic soft drinks due to its unique features (high nutritive values, high organoleptic values and high stability) of the product.
