Embodiment 1
[0037] A kind of jelly jelly polysaccharide, its preparation process comprises the steps:
[0038] (1) Dry and pulverize the whole jelly grass, and control the pulverization particle size to 50-100 mesh;
[0039] In a water bath, mix 9g of jellygrass whole herb powder and 250mL of 1.5% sodium carbonate aqueous solution, control the temperature at 95°C and extract for 1.5h, and filter the obtained extract with medical gauze and two layers of gauze to make jelly jelly The slag is filtered clean;
[0040] (2), decolorize the filtrate obtained in step (1) with 20mL of 10% hydrogen peroxide per 100mL, and control the temperature at 50°C during the decolorization process;
[0041] (3), step (2) After the decolorization is completed, use a 10K hollow fiber membrane tube for ultrafiltration purification;
[0042] (4), the filtrate obtained after ultrafiltration and purification in step (3) was added to anhydrous ethanol with a volume of 70% of the feed liquid, and then the temperatu...
