Abstract

The invention discloses a preparation method of earthworm extract with skin aging resistance. The method comprises the following steps: (1), soaking fresh earthworms in water until no silt exists, soaking the processed earthworms in saline water, continuing to soak the earthworms in a sterilizing solution, performing fishing out, and performing draining; (2), mashing the earthworms, adding water to prepare a solution, performing stirring reaction, then performing constant-temperature placement for 20-40min, and performing filtration to obtain enzymatic hydrolysate and filter residues; (3), adding water into the filter residues to prepare a solution, adding protease to perform enzymolysis, and performing centrifugal filtration to obtain filtrate; and (4), mixing the enzymatic hydrolysate obtained in the step (1) and the filtrate obtained in the step (2) to obtain an extracting solution, carrying out decoloration and deodorization treatment, and then filtering by using an ultrafiltrationmembrane to obtain an earthworm extract. The method is simple in process, mild in condition and free of pollution; the obtained earthworm extract has the capacity of removing superoxide anion free radicals and hydroxyl free radicals; growth and proliferation of human skin fibroblasts can be effectively promoted; and the earthworm extract can be applied to the fields of health care products and cosmetics and has an important application value.

Description

technical field [0001] The invention belongs to the technical field of biochemistry, and relates to a preparation method of an earthworm extract with anti-skin aging effect. Background technique [0002] Earthworm, commonly known as earthworm, is a high-quality animal protein resource, which belongs to commonly used traditional Chinese medicine. Antipyretic, anti-cerebral ischemia, anti-asthma, anti-bacterial, anti-oxidation, promotion of wound repair and cell regeneration. In addition, the polypeptide extract obtained by enzymatic hydrolysis of earthworms has physiological activities such as anti-oxidation, enhancing immunity, and antibacterial. [0003] At present, the use of earthworm extracts in the development of anti-aging skin products is still relatively small. In the preparation process of earthworm extract, in addition to mainly producing polypeptides, active ingredients such as amino acids and water-soluble small molecular fatty acids will also be produced. In ...
