This study investigates the effect of high hydrostatic pressure, also known as pressure processing (HPP), on microbial inactivation and changes in physicochemical characteristics carrot-orange juice blends at different pH values. HPP conditions (200–400 MPa, up to 5 m) were evaluated reach least 5-log L. innocua (ATCC 51742) each blend. 300 MPa for 2 m, 400 1 3 m achieved more than 6-log reduction 4, 5, 6 blends, respectively. Ascorbic acid (16–45 mg/100g), total carotenoid (66–241 mg/L),...

Abstract The residues left over from cold‐pressing oilseeds and fruits offer a promising source of plant proteins, serving as an alternative resource within the circular economy framework. This research aims to develop protein concentrates (PCs) pistachio meal with enhanced functional properties using ultrasound ‐assisted extraction (UAE). A response surface methodology was employed optimize UAE considering power (200–600 W), time (5–25 min), pH (8–11). Through Box–Behnken experimental...

Abstract Pea pod (PP) is an agricultural by‐product with 10%–13% protein content which has a potential to be converted value‐added ingredients. In this study, different extraction strategies including three solvents (water, salt, and alkaline) two pretreatments (ultrasound [US] enzyme such as pectinase Viscozyme®) before conventional alkaline were employed maximize the yield. The US‐pretreated achieved highest yield (21.1%) in extracts under optimum conditions (30% amplitude for 5 min). PP...

Thermal processing can intensify the degradation of beneficial compounds in fruit juices produced from concentrate, which underwent prior evaporation, leading to duplicated and likely increased quality deterioration. This study aims (i) investigate potential ultrasound (US) retain bioactive sour cherry juice (SCJ) concentrate (ii) involve insights digital image (IP) evaluate color attributes processed SCJs. US was optimized considering amplitude (60%–100%) time (2–15 min) as independent...
