Abstract Chicha is a traditional ethnic corn-based fermented beverage with a profound cultural relevance in the Andean region, especially in Peru where it has been part of religious ceremonies since pre-Inca civilizations. Chicha de Guiñapo is made with purple corn and is a typical beverage from the Peruvian region of Arequipa (South of Peru) where some local people still preserve its traditional process and use, but no investigation has been focused on the study of its potential health-relevant functional properties linking the historical perspectives. The current research was aimed at advancing the ethnic cultural relevance of this traditional beverage with an understanding of deep historical and ecological roots and further by evaluating the differences in the traditional processing of Chicha de Guiñapo from five geographical zones in Arequipa (Peru). Furthermore, to understand the potential health relevance, the influence on the total phenolic content (TPC), the total anthocyanin content (TAC), the antioxidant capacity, the in vitro inhibition of α-glucosidase and α-amylase relevant for hyperglycemia management, along with the physicochemical characteristics, were evaluated. No significant differences were observed in the physicochemical parameters, the antioxidant capacity, and the phenolic contents among the Chicha samples from different origins. However, all samples showed a remarkable in vitro inhibition of α-glucosidase and α-amylase with a significant influence of the geographical zone of origin that links historical usage and contemporary health benefits. The Z2 Chicha sample that followed the most traditional preparation had the highest values of TAC, in vitro antioxidant capacity, and anti-hyperglycemia-relevant α-glucosidase and α-amylase inhibitory activities. Results from the current study reveal that Chicha has an important health-relevant functional potential and that the preservation of the traditional historical and ethnic knowledge about its processing is critical for its validation for wider use across all communities.

Blueberry is a fruit consumed fresh and as an ingredient in formulations such as jam, juice, and wine. Wine is a widely consumed beverage and produced from different berries and fruits. Blueberry wine contains bio-compounds that could have a beneficial effect on health. Therefore, this study aimed to optimize blueberry wine by two response variables (total soluble solids and fermentation time) to obtain the highest alcohol percentage, pH, and lightness. In order to optimize the fermentation process, a central composite design was used. The optimized blueberry wine was obtained at total soluble solids of 25°Brix and fermentation time of 16 d. The optimized blueberry characteristics estimated were: alcohol percentage of 11.91%, pH of 2.98, and lightness (L*) of 26.22, and the optimized blueberry characteristics experimental were: alcohol percentage of 11.93±0.02%, pH of 2.97±0.01, and L* of 25.42±1.80. The optimized blueberry wine had a total phenolic content of 360.27±18.09 mg of gallic acid equivalents L-1, total anthocyanin content of 46.27±3.66 mg cyanidin-3 glucoside L-1, antioxidant capacity by ABTS and DDPH assays of 1,539.8±92.18 and 1,688.07±57.57 mM Trolox equivalent L-1, respectively. The results suggest that optimized blueberry wine can be considered a drink with potential health applications.

Purple corn (Zea mays L.) is native to the Andean region, but limited research has been performed about the potential metabolic variability when grown under Andean environmental conditions. This study was aimed at evaluating the phenolic and primary polar metabolites composition of purple corn (kernels and cobs) grown at two Peruvian Andean locations (lowland and highland) using targeted UHPLC (ultra-high-performance liquid chromatography) and untargeted GC-MS (gas chromatography mass spectrometry) metabolomic platforms, respectively. Changes in the physical characteristics and the in vitro bioactivity were also determined. Purple corn from the highland zone showed higher contents of ash, crude fiber, total phenolic contents, DPPH (2,2-diphenyl-1-picrylhydrazyl) antioxidant capacity, and α-amylase inhibitory activity in kernels, whereas increased levels of flavonoids (anthocyanins and quercetin derivatives) and ABTS [2,2ʹ-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)] antioxidant capacity were observed in cobs in comparison to lowland samples. No effect of the Andean location was found on the α-glucosidase inhibitory activity relevant for hyperglycemia management, while yield-linked physical characteristics were high in purple corn grown at the lowland zone. Polar primary metabolites related to the carbohydrate (monosaccharides, sucrose, and d-sorbitol), amino acid (valine and alanine), and tricarboxylic acid cycle (succinic, fumaric, and aconitic acid) metabolism were higher in highland purple corn (cob and kernel) likely due to abiotic stress factors from the highland environment. This study provides the foundation for further breeding improvements at Andean locations.

Berry fruits are rich in nutrients and polyphenols, providing potential health benefits. Understanding the factors that affect their bioavailability is becoming of utmost importance for evaluating their biological significance and efficacy as functional food. In this study, the phytochemical composition and the total antioxidant capacity of different varieties of five berries (blackberry, blackcurrant, blueberry, raspberry, and strawberry) were evaluated after an in vitro gastrointestinal digestion process. The cultivar of each berry that showed the higher content of total phenols and flavonoids was selected to study its cytotoxic effect on human hepatoma cells. Digestion resulted in a high reduction (p ˂ 0.05) of total phenolic, flavonoid and anthocyanin contents and total antioxidant capacity, in the “IN” samples compared to the “OUT” extracts, which represent the “serum-available” and the “colon-available” fractions, respectively. Incubation of the digested fraction for 24 h didn’t exert any effect on cellular viability, while a dose- and time-dependent cytotoxicity was observed after 48 h and 72 h of incubation for all the berries analyzed. Our results suggest that the approach proposed in this work may represent a rapid tool for evaluating and identifying new berries with increased phytochemical bioavailability, highlighting their antiproliferative agents after an in vitro digestion.

Honey is a well-known natural sweetener and is rich in natural antioxidants that prevent the occurrence of oxidative stress, which is responsible for many human diseases. Some of the biochemical compounds in honey that contribute to this property are vitamins and phenolic compounds such as phenolic acids and flavonoids. However, the extent to which these molecules contribute towards the antioxidant capacity in vitro is inconsistently reported, especially with the different analytical methods used, as well as other extrinsic factors that influence these molecules’ availability. Therefore, by reviewing recently published works correlating the vitamin, total phenolic, and flavonoid content in honey with its antioxidant activities in vitro, this paper will establish a relationship between these parameters. Based on the literature, vitamins do not contribute to honey’s antioxidant capacity; however, the content of phenolic acids and flavonoids has an impact on honey’s antioxidant activity.

In present study, fruit weight, fruit firmness, external fruit color, soluble solid content, pH, titratable acidity, vitamin C, total phenolics, total anthocyanins, and antioxidant capacity of eight wild bilberry grown in Coruh valley in northeastern Turkey were determined. The blueberry cv. ‘Bluecrop’ is also included study to make comparison with bilberry genotypes. Antioxidant activity of bilberry and blueberry fruits were comparatively assessed by FRAP (Ferric reducing antioxidant power) assay. Significantly higher content of phenolics and anthocyanins was found in bilberry fruits than in blueberry fruits. However blueberry cv. ‘Bluecrop’ exhibited higher fruit weight and vitamin C content than bilberry fruits. Total phenolic and total anthocyanin content was 327 mg gallic acid equivalent and 142 mg of cyanidin-3-glucoside equivalent in 100 g fresh fruit in cv. ‘Bluecrop’ while it was between 492-563 mg gallic acid equaivalent and 307-342 mg of cyanidin-3-glucoside equivalent in 100 g fresh fruits of  bilberry accessions. Moreover, wild accessions approximately had 2-3 folds higher antioxidant capacity than cv. ‘Bluecrop’. Results suggest the possibility of improving the bioactive and antioxidant properties of bilberry cultivars based food products by using wild ones in cross breeding. It was also concluded that genotypes significantly affect their bioactive content and consequently the possibility of using wild bilberry fruits as a potential source of natural antioxidants in food industry.

Nephelium lappaceum and its by-products have great potential in the agricultural, pharmaceutical, and food industries. Some studies have shown that N. lappaceum by-products exhibit antimicrobial, antioxidant, antidiabetic, and anticancer properties. However, studies focused on identifying these compounds are rare. The availability of polyphenolic compounds can vary according to environmental conditions, soil, plant variety, and agronomic management. Therefore, in this study, the active compounds in extracts of the N. lappaceum peel were identified, and their antioxidant properties were evaluated using various extraction solvents and both ultrasonic and boiling extraction techniques. The chemical characterization of the N. lappaceum peel exhibited carbohydrate and reducing sugar contents of 12 and 2%, respectively. Phytochemical analysis indicated the presence of flavonoids, tannins, terpenes, and steroids. The total phenolic and flavonoid contents and total antioxidant capacity were the highest in the hydroethanolic extract obtained by ultrasound, with values of 340 mg gallic acid equivalents g−1, 76 mg quercetin equivalents g−1, and 2.9 mmol of Trolox equivalents g−1, respectively. Contrarily, the total anthocyanin content was higher in the acid extract obtained by ultrasound, with a value of 0.7 mg cyanidin-3-O-glucoside equivalents g−1. A total of 18 compounds—including hydroxybenzene, phenolic acid, flavonoids, fatty acids (saturated, unsaturated, and ester), vitamin, arenecarbaldehyde, and phthalate—were identified for the first time in the N. lappaceum peel using gas chromatography-mass spectrometry. The identified compounds have been previously isolated from other plants and reportedly exhibit anticancer, anti-inflammatory, antimicrobial, and antioxidant activities. Thus, the N. lappaceum peel was shown to be a potential source of bioactive compounds of immense importance in the pharmacological and food industries.

Abstract Objectives The objective of this work was to evaluate the potential of common bean phenolic extract to exert anti-aging and antioxidant effect by inhibiting the collagenase, elastase, tyrosinase enzymes and free radicals. Methods 18 varieties of common bean (Phaseolus vulgaris L.) from Chiapas, Mexico, were analyzed for total phenolic content (TPC) and total anthocyanin content (ACN). Supercritical fluid (SCF) and leaching extractions were used for phenolic compounds extraction. Antioxidant capacity was evaluated using DPPH and ABTS scavenging assay. The inhibitory potential of the extract was evaluated for tyrosinase from mushroom, collagenase type-1 from Clostridium histolycum and elastase from porcine pancreas enzymes. Results The TPC ranged from 3.8–34.33 mg GAE/g coat and ACN ranged from 0.04–9.41 mg C3GE/g coat among the 18 common bean varieties (P < 0.05). The cultivar selected for this study was black bean with a TPC of 27.45 ± 0.7 mg GAE/g coat and ACN of 5.3 ± 0.1 mg C3GE/g coat. The best extraction conditions for the obtention of phenolic compounds and anthocyanins were SCF water-ethanol 50% as cosolvent, obtaining 66.60 ± 7.4 mg GAE/g coat (TPC) and 7.3 ± 0.6 mg C3GE/g coat (ACN). TPC and ACN content between each extraction process were statistically different (P < 0.05). For DPPH scavenging assay the IC50 for the black bean extract was 0.32 ± 0.01 mg GAE/g coat, and 0.40 ± 0.03 mg GAE/g coat for ABTS assay. Finally, the IC50 for the enzymatic inhibition assays of tyrosinase, collagenase and elastase were 10.44 ± 1.32, 8.33 ± 0.65 and 0.11 ± 0.02 mg GAE/g coat, respectively. Conclusions Black bean (Phaseolus vulgaris L.) extract presents high antioxidant capacity and inhibitory potential for tyrosinase and metalloproteinases such as collagenase and elastase. Black bean phenolic extracts could be used in cosmeceutical products related to preventing oxidative stress and aging.
