Walnut is the residue of walnut after crushing. In recent years, walnut meal is no longer simply used as feed or discarded directly, but extracted by various processes and reused. Some studies have shown that the protein content of walnut skillfully reaches 43.23%, which can be used to prepare bioactive peptides. At the same time, walnut meal extract is rich in cheese and has certain antioxidant activity. Studying the effect of walnut meal extract on tyrosinase activity and antioxidant activity is conducive to the development of freckle-removing products with walnut meal extract as the main ingredient. At the same time, this product does not need to add other antioxidants, whitening the freckles at the same time, it will not cause irritation or damage to the skin.
The extract of walnut had obvious inhibitory effect on tyrosinase activity, and the inhibitory intensity was dependent on the concentration of walnut extract. With the increase of extract concentration, the inhibition rate of tyrosinase activity increased. Juglans walnut extract has a significant inhibitory effect on tyrosinase activity, and tyrosinase is the main rate-limiting enzyme in the synthesis of black pigments. Therefore, walnut extract can reduce melanin synthesis by inhibiting the activity of tyrosinase. So as to achieve the effect of freckle removal.
Walnut meal extract is a reversible inhibitor of tyrosinase, which inhibits the activity of tyrosinase and reduces the catalytic activity of tyrosinase through some reversible interaction with the enzyme molecule, rather than by reducing the amount of effective enzyme, thus walnut meal extract is a reversible inhibitor of tyrosinase.
