Sustainable Extractions for Maximizing Content of Antioxidant Phytochemicals from Black and Red Currants.

ABSTRACT: Sustainable extraction techniques (ultrasound-assisted extraction (UAE), microwave-assisted extraction (MAE), and pressurized-liquid extraction (PLE)) were applied and compared with conventional solvent extraction to evaluate their efficiency in maximizing the bioactive compound content and antioxidant activity of black and red currants. The influence of ethanol concentrations (30%, 50%, 70%) were studied in all extraction methods, while different temperatures (30, 50, 70 °C/80, 100, 120 °C) were evaluated in UAE and PLE, respectively. Generally, higher total phenolics were determined in black currant extracts (1.93-3.41 g GAE/100 g) than in red currant extracts (1.27-2.63 g GAE/100 g). The results showed that MAE was the most efficient for the extraction of bioactives from black currants,
