| Popis: | Forward osmosis (FO) and emulsification with dynamic membranes of tunable pore size (DMTS) were assessed to concentrate and encapsulate polyphenol extracts from carob pulp. In the FO step, a feed solution temperature of 40 °C resulted in the fastest concentration and the highest polyphenol yield. Moreover, FO at 35 °C enabled to concentrate up to about 20 times in 3 h using a pilot scale unit of 0.5 m2 of membrane area. Phenolic compounds were subsequently encapsulated in the inner water phase (W1) of water-in-oil-in-water (W1/O/W2) emulsions produced with DMTS, which enabled to obtain emulsions with a monomodal droplet size distribution (span |
