Embodiment 1
[0018] A kind of ultrasonic extraction technology of sugarcane polysaccharide, comprises the following steps:
[0019] (1) Pretreatment: first send the bagasse into a microwave vacuum dryer, dry it at a pressure of 12KPa and a temperature of 40°C, and then crush the bagasse to a fine powder with a fineness of 60 mesh to obtain sugarcane powder;
[0020] (2) Ultrasonic treatment: add sugarcane powder to 8 times of water and stir evenly, then add acid to adjust the pH value of the solution to 6, then send it into the ultrasonic equipment, and process it for 8 minutes under the conditions of ultrasonic power of 40KHz and temperature of 60°C , to obtain ultrasonic treatment solution;
[0021] (3) Decoction: decoct the ultrasonic treatment solution for 100 minutes, filter to obtain the water extract, add 6 times of water to the filter residue and decoct for 50 minutes, filter to obtain the water extract, and combine the two water extracts;
[0022] (4) Impurity removal: send the w...
