Natural deep eutectic solvents (NADES) coupled with ultrasound assisted extraction (UAE) was evaluated as extraction techniques for bioactive compounds from apple pomace. Seven natural deep eutectic solvents (NADES) with different molar ratios were explored as green extraction solvents to evaluate extraction efficiency in terms of total flavonoid content (TFC), total phenolic content (TPC), lipid peroxidation inhibition (LBI) and antioxidant potential. The solvents which performed better than conventional solvent were DES1 (Choline chloride: glycerol (1:2)), DES2 (Choline chloride: lactic acid (1:3)) and DES5 ((Choline chloride: citric acid (1:1)). These solvents were further evaluated for optimisation of processing parameters in UAE-DES. The maximum TPC value was achieved using sonication time 40 min, water 30 %, solid/liquid ratio 1:30, temperature 40 °C, acoustic intensity 83.2 W/cm

In this study pomegranate peel extract was evaluated as source of antioxidant encapsulated by nano-emulsions in soybean oil. Encapsulating agents maltodextrin (MD), whey proteins isolate (WPI) and complex of maltodextrin and whey protein isolate (MD/WPI) (1:1) were used as wall material. Average droplet size of primary W/O and double W/O/W nanoemulsions stabilised by MD, WPI and MD/WPI were 108 nm, 157.82,189.94 nm and 191.12 nm respectively. Lyophilised nanoemulsion powders were added at 100, 200 and 300 ppm concentration to soyabean and mustard oil and observed for change in various oxidative stability indices during storage and were compared to non-encapsulated extract and synthetic antioxidant BHT. From the results, it can be suggested that nanoencapsulated extract at 300 ppm concentration performed better in controlling oxidative changes in both oils than unencapsulated and synthetic one, however, extract encapsulated by MD/WPI exhibited higher antioxidant effects due to controlled release of bioactive compounds.
