Identification and characterization of novel antioxidant protein hydrolysates from kiwicha (amaranthus caudatus l.)

: Kiwicha (Amaranthus caudatus) is considered one of the few multipurpose pseudocereals for its potential use not only as a source of nutrients and fiber but also for its bioactive compounds. In recent years, antioxidant peptides are commonly used as functional ingredient of food. Herein, a kiwicha...
