Embodiment 1
[0020] A method for extracting rice bran active polysaccharides, comprising low-temperature microwave treatment, compound enzyme enzymolysis and enzymolysis solution purification, the specific steps are as follows:
[0021] 1) Low-temperature microwave treatment: select the dried rice bran, crush it and pass it through a 60-mesh sieve to get rice bran powder, add water to the rice bran powder and stir evenly, the weight ratio of rice bran powder to water is 1:8, and then use 350W microwave power, Microwave extraction was performed at 40°C, extracted 3 times, each time for 40 minutes, filtered after the end, collected the filtrate, and the filter residue was used for later use. The pharmacological activity of the active polysaccharide depends on the integrity of its triple helix structure, and this triple helix structure is Maintained by hydrogen bonds, it is easy to destroy the binding force between hydrogen bonds at high temperatures. Low-temperature extraction can reduce the ...
Embodiment 2
[0030] A method for extracting rice bran active polysaccharides, comprising low-temperature microwave treatment, compound enzyme enzymolysis and enzymolysis solution purification, the specific steps are as follows:
[0031] 1) Low-temperature microwave treatment: select the dried rice bran, crush it and pass through an 80-mesh sieve to get rice bran powder, add water to the rice bran powder and stir evenly, the weight ratio of rice bran powder to water is 1:10, and then use 450W microwave power, Microwave extraction was carried out at a temperature of 50°C, extracted 4 times, 40 minutes each time, filtered after the end, the filtrate was collected, and the filter residue was used for later use;
[0032] 2) Compound enzyme enzymatic hydrolysis: add 8 times the weight of rice bran residue to deionized water containing sorbitol and L-dimethyl tartrate to rice bran residue after low-temperature microwave treatment, stir evenly, and then add compound enzyme with 0.9% weight of rice ...
Embodiment 3
[0040] A method for extracting rice bran active polysaccharides, comprising low-temperature microwave treatment, compound enzyme enzymolysis and enzymolysis solution purification, the specific steps are as follows:
[0041] 1) Low-temperature microwave treatment: select the dried rice bran, crush it and pass through an 80-mesh sieve to get rice bran powder, add water to the rice bran powder and stir evenly, the weight ratio of rice bran powder to water is 1:10, and then use 400W microwave power, Microwave extraction was carried out at a temperature of 50°C, extracted 4 times, each time for 50 minutes, filtered after the end, the filtrate was collected, and the filter residue was used for later use;
[0042] 2) Composite enzyme enzymatic hydrolysis: add 8 times the weight of rice bran residue to the rice bran residue after low-temperature microwave treatment, and stir evenly, then add 0.9% rice bran residue Enzyme hydrolysis for 60 minutes, control the enzymatic hydrolysis temp...
