Enzymolysis Technology Optimization for Production of Antioxidant Peptides from Goat Milk Casein

Enzymolysis Technology Optimization for Production of Antioxidant Peptides from Goat Milk Casein

Antioxidant peptides can inhibit lipid peroxidation and scavenging free radicals, maintain the balance of free radicals, and against a variety of diseases. Response surface methodology was used to optimize process conditions for producing antioxidative peptides from goat’s milk casein hydrolysate wi...
