Preparation method of lactobacillus reuteri whole grain fermentation system with high viable count

The invention discloses a preparation method of a lactobacillus reuteri whole-grain fermentation system with a high viable count, which comprises the following steps: by taking natural grains as a culture medium, sterilizing at high temperature, cooling, and adding lactobacillus reuteri for anaerobic fermentation to obtain the lactobacillus reuteri whole-grain fermentation system with the viable count of 10-15 Log10 CFU/mL; the natural cereals can obviously promote the growth of the lactobacillus reuteri, so that the high-density culture of the lactobacillus reuteri is realized; according to the lactobacillus reuteri whole-grain fermentation system, lactobacillus reuteri and whole grains are tightly combined to obtain lactobacillus reuteri whole-grain fermentation liquor with high viable count, and the fermentation liquor has the advantages of the whole grains and probiotics and can be used for producing fermented milk, fermented milk beverages and functional foods. 本发明公开了一种高活菌数的罗伊氏乳杆菌全谷物发酵体系的制备方法，以天然谷物为培养基质，
