Abstract
The invention relates to a pearl shell melanin inhibiting peptide with a whitening effect and application thereof. The pearl oyster melanin inhibiting peptide has the amino acid sequence shown in SEQ ID NO:1, specifically: SPSSS (Ser-Pro-Ser-Ser-Ser). The inventor of the invention discovers that the pearl oyster melanin inhibiting peptide can inhibit melanin generation, has good whitening activity and good safety, and can be widely applied to the fields of medicines, functional foods, cosmetics and the like.
Description
Technical Field
The invention relates to the technical field of active peptides, in particular to a pearl shell melanin inhibiting peptide with a whitening effect and application thereof.
Background
Melanin can reduce damage to skin caused by Ultraviolet (UV) radiation, but excessive melanin generation can cause skin problems such as chloasma, freckle and senile plaque, and even cause related diseases such as melanoma. Substances such as ascorbic acid, kojic acid, hydroquinone and arbutin are often used as effective active ingredients for skin antioxidation and whitening, but have limited application due to the problems of poor stability or strong toxicity, etc. Because of the wide demand for whitening agents in the fields of foods, medicines and cosmetics, a safe and stable natural active substance capable of inhibiting melanin generation is sought, for example, a group of small peptides capable of inhibiting melanin generation are provided by Chinese patent named antioxidant small peptides capable of inhibiting melanin generation, a preparation method and application of the antioxidant small peptides. However, there is still little research on natural peptides that inhibit melanogenesis.
