BIOPROCESSING OF ATLANTIC SALMON (Salmo salar) BY-PRODUCTS: RECOVERY AND ANTIOXIDANT PROPERTIES OF PROTEIN HYDROLYSATES
Yield, functional properties and antioxidant activities of salmon by-product protein hydrolysates derived from processing waste were investigated. Atlantic salmon by-products were ground and bioprocessed with the addition of formic acid/ lactic acid bacteria/ Flavourzyme to recover protein hydrolysa...
