Embodiment 1

[0042] Example 1: Industrial extraction of mussel polysaccharides

[0043] Mussel Polysaccharide Extraction:

[0044] (1) Raw material processing: take the dried frozen and boiled thick-shelled mussels produced in Shengsi County, Zhejiang Province as raw material, pulverize them with a pulverizer, and pass through a 20-mesh sieve to obtain dried mussels powder;

[0045] (2) Polysaccharide extraction: put the mussel dry powder prepared in step (1) into an extraction tank, add 6 times the volume of water, extract at 100°C for 2 hours, and the stirring blade speed is 60 rpm;

[0046] (3) Slag removal: separate mussel meat residue and polysaccharide extract with a 50-mesh screen;

[0047] (4) Enzymolysis: Adjust the pH of the polysaccharide extract prepared in step (3) to 8.0 with NaOH, add alkaline protease with a mass ratio of 0.2%, and enzymolyze at 50°C for 2 hours, and then heat it at 80°C after the enzymolysis is completed Inactivate under high temperature for 15 minutes t...

[0061] (1) Raw material processing: take the dry frozen and boiled purple mussel produced in Shengsi County, Zhejiang Province as raw material, pulverize with a pulverizer, and pass through a 20-mesh sieve to obtain dried mussel powder;

[0062] (2) Polysaccharide extraction: put the mussel dry powder prepared in step (1) into an extraction tank, add 6 times the volume of water, extract at 100°C for 2 hours, and the stirring blade speed is 60 rpm;

[0063] (3) Slag removal: separate mussel meat residue and polysaccharide extract with a 50-mesh screen;

[0064] (4) Enzymolysis: adjust the pH of the polysaccharide extract obtained in step (3) to 8.0 with HCl, add alkaline protease with a mass ratio of 0.2%, and enzymolyze it at 50°C for 2 hours, and heat it at 80°C after the enzymolysis is completed Inactivate under high temperature for 15 minutes to obtain enzymatic hydrolysis solution;

[0065] (5) Filtration: with diatomite as a filter aid, filter the enzymolysis solution pr...

Embodiment 3

[0070] (1) Raw material processing: take the dry frozen and boiled purple mussel produced in Shengsi County, Zhejiang Province as raw material, pulverize with a pulverizer, and pass through a 40-mesh sieve to obtain dried mussel powder;

[0071] (2) Polysaccharide extraction: put the mussel dry powder prepared in step (1) into an extraction tank, add 5 times the volume of water, extract at 90°C for 4 hours, and the stirring blade speed is 30 rpm;

[0072] (3) Slag removal: separate mussel meat residue and polysaccharide extract with 80 mesh sieves;

[0073] (4) Enzymolysis: adjust the pH of the polysaccharide extract prepared in step (3) to 8.0 with HCl, add alkaline protease with a mass ratio of 0.1%, and enzymolyze at 50°C for 3 hours, and then heat it at 80°C after the enzymolysis is completed Inactivation at high temperature for 20 minutes to obtain enzymatic hydrolysis solution;

[0074] (5) Filtration: with diatomite as a filter aid, filter the enzymolysis solution prep...

According to the method, frozen cooked dried mussels are taken as the raw materials, the preparation method comprises steps of raw material pretreatment, extraction, dreg removal, enzymatic hydrolysis, filtration, ethanol precipitation, dehydration, filtration, and drying, the finished product of mussel polysaccharide is white powder, the yield of polysaccharide is 7.9 to 12.4%, and the content of mussel polysaccharide is 82 to 92%. The provided method has the advantages that the technology is simple, green, and environment-friendly, the polysaccharide yield is high, the purity is high, the method is suitable for industrialized enlargement, the steps are simple, the operation is convenient, and the practicality is strong.

Description

technical field [0001] The invention belongs to the field of deep processing of aquatic products, in particular to an industrial extraction method of mussel polysaccharide. Background technique [0002] Mussel (Mytilus sp.) belongs to a kind of bivalve shellfish and is an important species in marine shellfish farming. It is also known as sea red, commonly known as "egg in the sea". Due to the large output of mussels, it is not easy to preserve after harvesting, so they have always been cooked and processed into dry products - mussels. Mussels have high nutritional value and certain medicinal value, which are recorded in "Compendium of Materia Medica", "Supplements to Materia Medica" and "Rihuazi Materia Medica". Modern pharmacological studies have shown that mussels have the functions of improving immunity, anti-tumor, scavenging oxygen free radicals, anti-atherosclerosis, lowering blood lipids, inhibiting the formation of thrombus, improving myocardial oxygen supply and pr...
