Oysters, also known as oysters, raw oysters, oysters, also known as sea oysters, oyster yellow, oyster white, green oysters, clams, oyster clams, oysters, etc., belong to the phylum Bivalvia. Oysters are produced at the junction of sea water or brackish water and feed on plankton.

Product Introduction:

Oyster peptide is a protein extracted from oyster powder, and then obtained by directed enzyme digestion and specific small peptide separation technology. Among them, the relative molecular weight is less than 1000Da hydrolysate accounts for more than 85%. Oyster peptide not only contains amino acids, vitamins, trace elements and taurine in the right proportion, but also contains a variety of nutrients from marine organisms.

The extraction process of oyster peptides:

1. Cleaning steps:
The oysters are washed according to the set washing time to form washed oysters.

2. Cooking steps:
Put the water into the steaming device, put the weighted oysters while heating up, and stir them simultaneously. After the temperature reaches the set insulation range, stop the heating, and keep the insulation according to the set insulation time. After the insulation, stop stirring, and then follow Set the standing time to stand still to form a soup.

3. Steps for soup decoction:
The extraction device is used to extract the primary soup and pump into the primary soup storage device.

4. Hydrolysis steps:
Pump the primary soup in the primary soup storage device into the hydrolysis device, heat it up to the set sterilization temperature and maintain it according to the set sterilization time, then cool it down to the set enzymatic hydrolysis temperature, add the configuration solution to reduce the pH of the primary soup Adjust the value to neutral, put in the animal protease preparation for hydrolysis, and keep it until the set enzymolysis time. After enzymolysis, the temperature is raised to the set enzymatic inactivation temperature and kept until the set enzymatic inactivation time to form a hydrolyzed solution after enzymolysis. .

5. Filtering steps:
Put the enzyme-inactivated hydrolysate into diatomaceous earth and/or activated carbon and then let it stand, and filter it to the clear liquid storage device using a filtering device, and then use the circulating filtering device to circulate the clear liquid according to the set cycle filtering time filter.

6. Concentration steps:
The circulating filtered clear liquid is concentrated to a set concentration concentration to form a clear concentrated liquid.

7. Spray drying steps:
The clarified concentrated liquid is spray-dried according to the set inlet air temperature and the set outlet air temperature to form oyster peptide powder
