Abstract:
... Stilbenes are a family of phenolic secondary metabolites that are known for their important roles in plant protection and human health. Numerous studies show that vine shoots, one of the most abundant winery wastes, could be used as a source of bioactive compounds such as stilbenes. The predominant stilbenoids in vine shoots are trans-resveratrol (Rsv) and -viniferin (Vf), whose content varies dep ...

Abstract:
... This work is aimed at optimising the spray drying conditions of the phenolic extracts of purple mashua microencapsulated with octenyl succinic anhydride (OSA) Andean tuber starches. Purple mashua extracts were obtained and spray dried using native and OSA starches of yellow oca, pink oca, and yellow olluco (140°C, 4% starch). The powders obtained were analysed by encapsulation efficiency of anthoc ...
... 'Gola' jujube was irradiated by gamma irradiation doses (0, 0.4, and 1.0 kGy) and stored at 10°C for 35 d. The impact of irradiation on nutritional (total soluble solids, firmness, titratable acidity, pH value and sugars) and bioactive attributes (ascorbic acid, total phenol, total carotenoid and antioxidant activity) were evaluated at 7 d interval. The total soluble solids of ‘Gola’ jujube was si ...
... Currently, consumption of confectionery continues to grow, and there is a tendency to supplement snacks with ingredients that can be considered as functional products. The aim of this study was to evaluate the benefits of sprouted barley grains and their potential use in barley-fruit-vegetable snack production. Several samples of sweet bars with hulless barley variety ‘Kornelija’ flour and sproute ...

Abstract:
... This study investigated the effect of ultrafiltration (UF) combined with high‐pressure processing (HPP) at 550 MPa, 25 °C for 5 min, ultrasound (US) at 520 W, 40 °C for 10 min and heat treatment (HT) at 90 °C for 3 min on the microbial, physicochemical and sensory properties of a blueberry–grape–pineapple–cantaloupe juice blend during 104 days of storage at 4 °C. After UF, the shelf life of the HP ...

Abstract:
... We studied plant-based milk from soya beans as a means to release and convey the bound antioxidants in turmeric to benefit consumer health. This was compared to cow milk as a carrier because soya milk consumption as an alternative to cow milk is increasing globally. Hence, turmeric paste was added to milk to investigate the release of turmeric antioxidants when changing the matrix (cow vs. soy), t ...

Abstract:
... The marketability of pointed gourd fruit is drastically reduced after harvest due to moisture loss, chlorophyll degradation, yellowing of the skin, and shriveling. The present investigation studied the effect of exogenous salicylic acid (SA) treatment on senescence and fruit quality attributes of pointed gourd during storage under ambient conditions. Fruits were treated by immersing them in differ ...
... Lichens produce range of secondary metabolites which exhibit multifarious biological potential. The present work highlights the effect of media components for the production of secondary metabolites by lichen Parmotrema austrosinense. Mycobiont was isolated by lichen tissue culture method. One variable at a time approach exhibited that, Malt yeast extract media supplemented with glucose (4 mg/L), ...
