Oyster peptide is a peptide molecular biotechnology applied to oyster processing process, through enzymatic hydrolysis oyster peptide. This kind of method to form the small molecules of low poly peptide, fully retain the original vitamins, trace elements and taurine oysters and other nutritional ingredients, after making the oysters in the human body rich in nucleic acid intake is quicker than the single absorption of amino acids or proteins, are more likely to be absorbed by the body, has more important biological activity in human metabolism, can effectively improve male serum testosterone levels. Compared with ordinary oyster products, oyster products have higher biological potency and more important physiological functions.

Oyster peptide introduction to edit speech
Oyster peptide is the main ingredient of oyster, commonly known as Oyster and Oyster, which is a kind of shellfish abundant in coastal areas of China and can be cultivated in large quantities. There are more oysters abroad. Oysters are a traditional tonic. Glycogen, the main component, can quickly replenish and restore physical strength and improve immunity [1].
Nutrition research edited speech
Studies show that oyster meat is rich in a variety of minerals and trace elements, including calcium 40-94.04mg/g, iron 5.50-8.00 mg/g, selenium 49.00 mg/g, zinc 22.54 mg/g. Taurine content in oyster meat (dry) extract was 50.6 mg/g, much higher than clams, squid, sea cucumbers and other seafood.
Crassostrea mytilus from Bohai Bay is rich in taurine (50μmol/g), zinc and selenium. Low fat, low cholesterol, containing a certain amount of highly unsaturated fatty acids (EPA+DHA 20.4% of the total fat), inorganic salt, vitamin content is also very rich. All the 8 essential amino acids of human body were found in Pacific oyster, Capuchin oyster and Neijiang oyster, among which lysine was the highest, which was of great significance to balance the proportion of amino acids in national diet. Taurine contents in the three oysters were as high as 7.542, 4.388 and 3.591mg/g, respectively, almost exceeding the sum of other free amino acid contents [1].
Health function edit speech
A large number of clinical data have confirmed that oyster can improve the level of testosterone in male serum, regulate blood lipids, inhibit platelet aggregation, improve the symptoms of hyperglycemia, improve human immunity, promote metabolism and other functions, and also have certain effects on anti-cancer and preventing the spread of cancer cells.
1. Enhance male sexual function
Oyster peptide can effectively improve the level of serum testosterone and enhance male sexual function. At the same time, it has the dual functions of regulating the body's physiological function and improving nutrition for the body.
2. Protect the liver
Oyster powder extract has a good protective effect on experimental liver injury, can significantly reduce the content of ALT/AST in serum of cc14-induced impromptu liver injury, and reduce the degree of stem cell injury.
3, enhance immunity
Oyster polysaccharide contained in oyster peptide can enhance the immune capacity of the body and inhibit the proliferation of influenza virus.
4, hypoglycemic effect
Oyster extract has the hypoglycemic properties of sulfonylureas and biguidine.
5, prevention of cardiovascular and cerebrovascular diseases
Oyster glycosaminoglycan has a protective effect on oxidative damage of vascular endothelial cells induced by hydrogen peroxide, and can effectively prevent hypertension, arteriosclerosis, stroke and other cardiovascular diseases caused by vascular endothelial injury.
6, anti-tumor effect
Oyster natural active peptide (BPO) can effectively inhibit the proliferation of GASTRIC cancer BCC-823 cells and significantly induce apoptosis of cancer cells.
Extraction process edit speech
Extraction process of oyster peptide:
1. Cleaning steps:
The oysters are cleaned according to the set cleaning time to form the cleaned oysters.
2, cooking steps:
Put the water into the cooking device, and put the oysters in the measured weight while heating up, and stir at the same time. When the temperature reaches the set insulation range, the temperature will stop, and the insulation will be carried out according to the set insulation time. After the insulation, the stirring will stop, and the standing time will be carried out according to the set standing time to form a soup.
3, the steps of soup:
The primary soup is extracted by an extraction device and pumped into a primary soup storage device.
4. Hydrolysis steps:
Will be described in a storage device in a soup pumping hydrolysis device, heat set sterilization temperature and keep, carried out in accordance with the set sterilization time and then cooled to set enzyme solution temperature, the liquid will join configuration a soup PH adjustment to neutral, hydrolyzed into animal protease preparations, and keep to set the digestion time, to set out the enzyme digestion after warming temperatures, And keep to the set enzyme time, the formation of enzyme after the hydrolysate.
5. Filtration steps:
Put the hydrolysate after killing the enzyme into diatomite and/or activated carbon and stand, and filter it to the clear liquid storage device using the filter device, and then filter the clear liquid using the cycle filter device according to the set cycle filter time.
6. Enrichment steps:
The circulating filtered clear liquid is concentrated to a set concentration to form a clarified concentrate.
7. Spray drying steps:
The clarified concentrate is spray dried according to the set air inlet temperature and set air outlet temperature to form oyster peptide powder.
