Embodiment 1

[0020] The preparation process steps of oyster peptide are as follows:

[0021] S1. Put 50g of shelled oyster meat into the cleaning tank, then add water to the cleaning tank to rinse the sticky matter adhering to the raw oyster meat; then inject clean water and completely submerge the oyster meat, and then clean the cleaning tank. Stir with ultrasonic vibration for 30 minutes; repeat this step 4 times to remove impurities on the surface of the oyster meat until the surface of the oyster meat is cleaned;

[0022] S2. Then pour 10% physiological saline into the clear water tank, soak the oyster meat for 30 minutes, remove the sticky matter in the oyster meat, then remove the physiological saline, wash the oyster meat with water again, and remove the hydrochloric acid solution; then mince the oyster meat , the slurry was obtained, vacuum packed and stored at -40°C for later use;

[0023] S3, pour the slurry into the enzymolysis reaction tank, and add deionized water (500g) of 1...

Embodiment 2

[0029] The preparation process steps of oyster peptide are as follows:

[0030] S1. Put 10g of raw oyster meat into the cleaning tank, then add water to the cleaning tank to rinse the sticky matter adhering to the raw oyster meat; then inject clean water and completely submerge the raw oyster meat, and then perform ultrasonic vibration stirring on the cleaning tank 60 minutes; repeat this step 6 times to remove impurities on the surface of the oyster meat until the surface of the oyster meat is cleaned and set aside;

[0031] S2. Then pour 10% physiological saline into the clear water tank, soak the oyster meat for 30 minutes, remove the sticky matter in the oyster meat, then remove the physiological saline, and clean the oyster meat again; then mince the oyster meat to obtain a slurry , vacuum packed and stored at -40°C for later use;

[0032] S3. Pour the slurry into the enzymolysis reaction tank, and add deionized water (100g) of 10 times the weight of oyster meat in the e...

Abstract

The invention belongs to the field of oyster peptide preparation, and discloses a preparation method of oyster peptide, comprising the following process steps: washing oyster meat, grinding the oyster meat to obtain slurry, performing enzymatic hydrolysis on the slurry, and performing enzyme-killing treatment at 100°C, The supernatant was obtained by centrifugation, decolorized by activated carbon, then filtered by suction, and freeze-dried at low temperature to obtain oyster peptides. The preparation process of the invention is simple, the amount of enzyme used is small, the enzymolysis time is short, and the production cost is low.

Description

technical field [0001] The invention relates to the technical field of oyster peptide extraction, in particular to a preparation method of oyster peptide. Background technique [0002] Many active substances in the human body exist in the form of peptides. Without peptides, there will be no activity and no life. In the human body, peptides are involved in the growth of hormones, nerves, and cells of the human body; they can be used as a transportation tool in the human body to transport various nutrients, vitamins, and trace elements eaten by the human body to the cells, organs, and tissues of the human body. Therefore, people pay more and more attention to peptides. [0003] In recent years, researchers have begun to pay attention to extracting biological peptides from aquatic animals, such as extracting oyster peptides from oysters. However, in the existing process for extracting oyster peptides from oysters, the amount of enzymes used in the enzymatic hydrolysis process...
