Abstract

The invention relates to a preparation method of a pearl hydrolysate. The method comprises the following steps of: (1) adding pearl powder in an aqueous solution of hydrochloric acid, stirring until the pearl powder and the aqueous solution of hydrochloric acid fully react, adjusting the pH value of the mixed solution with ammonia to be neutral and centrifugating to obtain a sediment (A); (2) dissolving the sediment (A) with purified water, adjusting the pH value of the solution with ammonia to be 7.5-8.5 and centrifugating to obtain a sediment (B); (3) dissolving the sediment (B) with purified water, adding enzyme for enzymolysis, centrifugating an enzyme solution to obtain a supernatant and a sediment (C), wherein the enzyme is the mixture of snail protease and pawpaw protease, and the addition of the enzyme is 0.3-1.05 percent by weight of the sediment (B); (4) dissolving the sediment (C) with purified water, adding enzyme for secondary enzymolysis, centrifugating and collecting a supernatant, wherein the enzyme is the mixture of the trypsinase, the pawpaw protease and neutral protease, and the addition of the enzyme is 0.2-0.45 percent by weight of the sediment (B); and (5) mixing the two supernatants, boiling and filtering with a nanofiltration membrane with the aperture of 1-3nm to obtain the pearl hydrolysate.

Description

technical field

[0001] The invention relates to a method for preparing a hydrolyzate, in particular to a method for preparing a pearl hydrolyzate. Background technique

[0002] Pearl is a precious Chinese herbal medicine. Pearl is formed by the nacre secreted by the mantle of the mother-of-pearl and the epidermal cells of the pearl sac. The main component of pearls is calcium carbonate, which accounts for about 82-93% of the total. In addition, pearls also contain 4-14% shell keratin protein and 2-4% water, as well as more than ten kinds of amino acids and 28 kinds of trace elements. These include anti-aging substances such as selenium and germanium. Shell keratin can be dissociated into amino acids under appropriate conditions. Amino acid is the basic unit of protein, and protein is the life basis of our body, and it is a necessary substance for regulating physiological functions and supplying heat. Li Shizhen recorded in "Compendium of Materia Medica": "(Pearl) calms co...
