Recently, good news came from the State Intellectual Property Office that the patent application for “A bonito elastin peptide and its preparation method” produced by Hainan Huayan Collagen Technology Co., Ltd. (hereinafter referred to as Hainan Huayan) has been approved and officially granted the patent right!

Elastin is highly hydrophobic and extensively cross-linked. It is an extremely insoluble hard protein that is insoluble in dilute acid, alkali, alcohol and salt solutions. It only swells in some polar solvents and is highly resistant to protease degradation. Elastin peptides are products prepared by protease hydrolysis of elastin, so the difficulty of elastin peptide production is greatly increased.

At present, most elastin peptides are prepared from bovine heart vessels, bovine ligaments and heart arterial bulbs of fish such as bonito. Fish elastin peptides have the characteristics of high safety and low immunogenicity, and are highly concerned by the market and consumers.

There are many researches have confirmed that oral administration of relatively low doses of elastin peptides can significantly improve skin condition and reduce the clinical manifestations of skin aging. It has the effects of increasing skin elasticity and water content, increasing collagen and elastin content, reducing skin wrinkles and pigmentation, and improving skin barrier. At present, elastin peptides powder have broad application prospects in the fields of food, oral beauty drinks and skin care products.
