Embodiment 1
[0021] ⑴Preparation of raw materials: After extracting the golden pear flavor, the clean golden pear dregs are dried at low temperature, crushed and passed through a 50-mesh sieve, and used as raw materials;
[0022] ⑵Hot water treatment: Put the raw materials directly into the multi-functional extractor, add 15 times the amount of distilled water, stir evenly, extract at 85°C for 2.0 hours, filter and separate to obtain the first extraction filtrate, and add the residue 10 times the volume of distilled water, stirred
[0023] Evenly, extract at 95°C for 1.5h, filter and separate to obtain the second extraction filtrate; combine the two extraction filtrates;
[0024] (3) Enzyme hydrolysis treatment: Add 15 times the amount of residue to distilled water, stir evenly, add compound enzyme with 3% amount of golden pear residue (complex enzyme includes 1.5% serrapeptase and 1.5% papain), at a temperature of 55 ℃, pH 7, enzymatic hydrolysis for 1.5h, then rapidly heated to 98°C to ...
Embodiment 2
[0030] ⑴Prepare raw materials: after extracting golden pear flavor, clean golden pear dregs, dry at low temperature, crush and pass through a 60-mesh sieve, and use it as raw material;
[0031] (2) Hot water treatment: Put the raw materials directly into the multifunctional extractor, add 15 times the amount of distilled water, stir evenly, extract at 85°C for 1.5 hours, filter and separate to obtain the first extraction filtrate, and add the residue 10 times the amount of distilled water, stir evenly, extract at 95°C for 1 hour, filter and separate to obtain the second extraction filtrate; combine the two extraction filtrates;
[0032] (3) Enzymolysis treatment: add the residue to 15 times the amount of distilled water, stir evenly, add 4% compound enzyme of golden pear residue (complex enzyme includes 2% serrapeptase and 2% papain), at 50 ℃, pH 6.8, enzymatic hydrolysis for 1.5h, then rapidly heated to 98°C to inactivate the enzyme, and kept for leaching for 0.5h, centrifuge...

[0039] A kind of preparation method of golden pear dregs crude polysaccharide, its specific steps are:
[0040] ⑴Preparation of raw materials: After extracting the golden pear flavor, the clean golden pear dregs are dried at low temperature, crushed and passed through an 80-mesh sieve, and used as raw materials;
[0041] (2) Hot water treatment: Put the raw materials directly into the multifunctional extractor, add 15 times the amount of distilled water, stir evenly, extract at 85°C for 1.5 hours, filter and separate to obtain the first extraction filtrate, and add the residue 10 times the volume of distilled water, stirred
[0042] Evenly, extract at 95°C for 1 hour, filter and separate to obtain the second extraction filtrate; combine the two extraction filtrates;
[0043] (3) Enzyme hydrolysis treatment: add the residue to 15 times the amount of distilled water, stir evenly, add 5% compound enzyme of golden pear dregs (complex enzyme includes 2.5% serrapeptase and 2.5% pap...
