The invention relates to a cerebroprotein
peptide and
casein hydrolysate composition and application thereof in improving sleep and memory, and belongs to the technical field of biological
protein peptides. According to the preparation method disclosed by the invention, Maillard modification of the
casein enzymolysis primary product is realized by screening the enzymolysis
protease of the
bovine milk casein and screening the carbonyl compound which is subjected to
Maillard reaction with the casein enzymolysis primary product, so that the reducing power, the
metal ion chelating capacity and the
antioxidant capacity of the
casein hydrolysate are effectively improved; furthermore, free radicals in the body are removed,
oxidative stress reaction is relieved, and a good foundation is laid for improving
sleep quality. The brain
protein peptide and the
casein hydrolysate are compounded, so that the sleep latency can be effectively shortened, the sleep rate can be increased, the sleep can be effectively improved, the content of
dopamine and noradrenaline in
hypothalamus can be reduced, the content of 5-hydroxytryptamine and the content of aminobutanoin can be increased, and the brain
protein peptide composition has good effects of relieving and treating sleep disorders and improving memory.
