Abstract
The present invention discloses an anti-aging sturgeon roe tetrapeptide, having a peptide sequence of NLPL (SEQ ID NO: 9). The present invention further discloses a preparation method of the anti-aging sturgeon roe tetrapeptide, specifically comprising the following steps: (1) adding deionized water to sturgeon roes and homogenizing to obtain a sturgeon roe homogenate; (2) adjusting a pH value of the sturgeon roe homogenate, adding alkaline protease, performing enzymolysis and enzyme inactivation, and cooling to obtain sturgeon roe enzymatic hydrolysate; and (3) centrifuging the sturgeon roe enzymatic hydrolysate, taking a supernatant to obtain anti-aging sturgeon roe tetrapeptide, and storing for later use. The sturgeon roe peptide prepared by the present invention can improve the levels of oxidative stress and skin related factors (type I collagen and hyaluronic acid) by adjusting a cell proliferation state, so as to realize the protective effect on skin cells at a cellular level.
