Embodiment 1
[0034] 1) Select the glutinous rice variety Dalinuo, weigh 100±0.1g of polished rice flour passed through a 100-mesh sieve into a 1000mL beaker, add 400mL 0.5mM AgNO 3 Solution, soaked at 4°C for 72h, wrapped in tin foil to avoid light to prevent AgNO 3 Breakdown to inhibit endogenous starch hydrolysis starch intergranular fillers. Stir 3-5 times during soaking;
[0035] 2) The polished rice flour suspension obtained in step 1) is placed on a magnetic stirrer and stirred at a speed of 300 rpm for 4-6 hours under the condition of avoiding light;
[0036] 3) Mix the suspension obtained in step 2) with 4 times the volume of glycerin with a purity ≥ 99.5%, and gently invert up and down and mix repeatedly;
[0037] 4) Put the mixture obtained in step 3) into a centrifuge bottle in a floor centrifuge, set the speed at 1200g / min, and centrifuge for 10min;
[0038] 5) Collect the precipitate and upper liquid obtained in step 4) respectively;
[0039] 6) Wash the precipitate obtain...

[0043] 1) Choose the japonica rice variety Chunjiang 151, weigh 100±0.1g of the polished rice flour of Chunjiang 151 through a 100-mesh sieve into a 1000mL beaker, add 400mL 0.5mM AgNO 3 Solution, soaked at 4°C for 72h, wrapped in tin foil to avoid light to prevent AgNO 3 Breakdown to inhibit endogenous starch hydrolysis starch intergranular fillers. Stir 3-5 times during soaking;
[0044] 2) The polished rice flour suspension obtained in step 1) is placed on a magnetic stirrer and stirred at a speed of 300 rpm for 4-6 hours under the condition of avoiding light;
[0045] 3) Mix the suspension obtained in step 2) with 4 times the volume of glycerin with a purity ≥ 99.5%, and gently invert up and down and mix repeatedly;
[0046] 4) Put the mixture obtained in step 3) into a centrifuge bottle in a floor centrifuge, set the speed at 1500g / min, and centrifuge for 10min;
[0047] 5) Collect the precipitate and upper liquid obtained in step 4) respectively;
[0048] 6) Wash the...
