The invention belongs to the field of functional peptides, and relates to a preparation method of oyster active peptide capable of improving senile cognitive dysfunction, which comprises the following steps: the oyster is subjected to alkali extraction, acid precipitation and protein extraction, enzymolysis is carried out by neutral protease, and ultrafiltration is carried out by an ultrafiltration membrane to obtain an ultrafiltration component of 5-8kDa, namely the oyster active peptide. The oyster active peptide has the effect of improving senile cognitive dysfunction. |
