Embodiment Construction

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0021] Such as figure 1 As shown, the invention provides a kind of preparation method of oyster nutrition powder, comprising:

[0022] Step 1. Shell and viscera the oysters, leave the oyster meat, rinse with clean water;

[0023] Step 2, mincing the oyster meat with a tissue grinder to obtain oyster meat slurry;

[0024] Step 3. Stir the oyster pulp and deionized water evenly according to the mass ratio of 1:5 to obtain the first puree. Use malic acid to adjust the pH value of the first puree to 3, and add the first puree to the first puree. Add 37 acid protease with 6% of the mass of the original slurry to the first original slurry, and enzymolyze it at 40°C for 3 hours;

[0025] Step 4. Raise the temperature to 90°C to inactivate 537 acid protease, centrifuge for the fir...

Abstract

The invention discloses a preparation method of oyster nutrition powder. The preparation method comprises the following steps: grinding clean oyster meat to obtain oyster meat paste; uniformly stirring the oyster meat paste with deionized water to obtain first raw paste, regulating the pH value to 3, adding 537 acid protease; inactivating the 537 acid protease and extracting to obtain second raw paste; performing reduced pressure distillation on the second raw paste to obtain third raw paste; and regulating the pH value of the third raw paste to 7, adding active carbon, removing the abnormal smell of the third raw paste, filtering out the active carbon, adding dried siraitia grosvenorii powder which accounts for 5% of the third raw paste in weight, stirring uniformly, performing the reduced pressure distillation, removing the dieionized water, drying in an oven to obtain the oyster nutrition powder. The oyster nutrition powder is sterilized at a high temperature and encapsulated in a vacuum condition. The oyster nutrition powder disclosed by the invention is high in extracting efficiency, rich in nutrition, and convenient to store and transport.

Description

technical field [0001] The invention relates to a preparation method of oyster nutrition powder, which belongs to the preparation method of nutritional products. Background technique [0002] Oyster meat is rich in glycogen, protein, amino acid, fat and trace elements, among which the protein content is as high as 50%, and the protein content is as high as 50%, which has a high nutritional value. However, oysters are not easy to preserve and are easy to deteriorate. At the same time, the content of heavy metals in oysters is high, and frequent direct use will cause heavy metal enrichment. How to extract amino acids and polypeptides in oysters is of great significance to the deep processing of oysters. Contents of the invention [0003] The invention designs and develops a preparation method of oyster nutrition powder. It can effectively extract amino acids and peptides in oysters. [0004] The technical scheme provided by the invention is: [0005] A preparation method ...
