Research Progress of Bioactive Peptides Derived from Milk Casein
Casein is the main component in milk,and it has been proven to be the main source of bioactive peptides through research.Functional small peptides are mainly released through the action of proteases and peptidases in the processes of gastrointestinal digestion or dairy fermentation.According to different sequences,structures and amino acid content,the generated polypeptides have different functions,such as regulating immunity,antibiosis,antioxidation,lowering blood pressure and sleep improvement,and are considered as potential components of functional foods.With the in-depth exploration of bioactive peptides derived from milk casein and the elucidation of the mechanism of their physiological functions,polypeptides derived from casein are expected to become potential functional food additives and polypeptide drugs,and have important application prospects in the development of specific foods and polypeptide drugs.In this paper,the research progress of milk casein polypeptide study,biological functions and mechanism of action at home and abroad are reviewed,in order to provide references for the research and application of bioactive peptides derived from milk casein.
