Enzymatic preparation of antioxidant peptides derived from proteins of livestock, poultry and aquatic origin has become a hot research topic around the world due to rich raw materials, high value-added benefits and good safety. This paper reviews the mechanism of action of antioxidant peptides and indicators of their antioxidant activity. Current methods for enzymatic preparation and structure-activity relationship of antioxidant peptides derived from proteins of livestock, poultry and aquatic origin are emphatically explored and existing problems and defects are pointed out. Meanwhile, the cu...
