This invention belongs to the field of functional substance research, specifically relating to the use of
casein hydrolyzed
peptide compositions in improving aging, and more specifically to their use in the preparation of products for improving aging. The
casein hydrolyzed
peptide compositions are obtained by enzymatically hydrolyzing
casein solution using
serine protease and
flavor protease. Furthermore, in the casein hydrolyzed
peptide compositions, the relative strength of total functional peptides is above 25%, the relative strength of casein phosphopeptides is above 9%, and the relative strength of functional peptides other than casein phosphopeptides is above 11%. This casein hydrolyzed peptide composition can effectively alleviate
oxidative stress caused by aging, inhibit chronic low-grade
inflammation, reduce aging-related damage to vital organs such as the liver and brain, improve the body's immune function, and improve the external
phenotype of aging, thereby comprehensively exerting an anti-
aging effect.
