Embodiment 1

[0026] This embodiment 1 provides the method of utilizing enzymatic hydrolysis to extract oyster polysaccharides from oysters, please refer to figure 1 , the above method will be described in detail below.

[0027] 1 Oyster meat extraction: select fresh oysters, extract the oyster meat inside, and then clean the extracted oyster meat.

[0028] 2 Grinding: Weigh 610kg of oysters, put them into a grinder and grind them for about 15 minutes. Observe the oysters through the observation window on the surface of the grinder. When the ground oyster meat cannot be observed, the next step of extraction can be carried out Already working.

[0029] 3 Extraction: 607kg of grinding liquid is put into the extraction tank. During the grinding process inside the grinder, there is a material cutting error, and 12.14 tons of water is added to the extraction tank, and then the entire extraction tank is heated. The temperature was allowed to rise to 100° C., held for 30 minutes, and then, thirt...

Abstract

The invention discloses a method for extracting oyster polysaccharides from oysters by enzymolysis. The method includes steps: selecting fresh oysters, extracting oyster meat in the selected fresh oysters, cleaning the extracted oyster meat, naturally drying the washed oyster meat, grinding into pulp in grinding equipment, quantitatively weighing ground oysters, proportionally compounding quantitative oyster meat and clear water, heating solution of the quantitative oyster meat and clear water, adding alkaline protease, performing enzymolysis, adding neutral protease, and continuing enzymolysis; after enzymolysis is finished, subjecting the solution to enzyme deactivation after enzymolysis, and canning. According to the method for extracting the oyster polysaccharides from the oysters by enzymolysis, high content of the oyster polysaccharides in oyster powder or oyster peptide powder can be guaranteed in a processing process.

Description

technical field [0001] The invention relates to the technical field of food and health food, in particular to extracting oyster polysaccharide from oysters by using an enzymatic hydrolysis method. Background technique [0002] Oysters are widely distributed in my country, from the Yalu River in the north to Hainan Island in the south, and can be produced along the coast. Oysters are rich in polysaccharides, and current studies have found that oyster polysaccharides can inhibit the proliferation of viruses and the growth of tumor cells in different ways. Oyster polysaccharides extracted from oysters have anti-tumor, anti-oxidation, anti-thrombosis and other effects. [0003] The oyster powder or oyster peptide powder extracted from oysters sold on the market today has a low content of oyster polysaccharides, which will indirectly cause a large amount of waste of oysters, and in the process of extracting oyster polysaccharides, cannot It is very suitable for large-scale prod...
