Microbiological method extracted lycium barbarum polysaccharide industrialization production process

The invention provides a microbiological method extracted lycium barbarum polysaccharide industrialization production process which comprises the following steps: A1, drying dried lycium barbarum at the temperature of 60 DEG C, crushing, screening by using a sieve of 50 meshes, and at the same time preparing a rice wine yeast bacterium; A2, putting a certain amount of a dried lycium barbarum powder raw material into an extraction tank, adding deionized water which accounts for 40 times of the amount of the raw material, and 5% of the rice wine yeast bacterium, heating with stirring to increase the temperature to 28 DEG C, keeping the temperature, and performing heat-preservation stirring extraction for 36 hours with stirring; A3, filtering a liquid after heat-preservation stirring so as to obtain supernate, and respectively extracting filtrate twice with 5 times of water and the rice wine yeast by using a same method. With the combination of the rice wine yeast bacterium and the deionized water, and the lyciu
