preparation example Construction
[0030] The present invention also provides a preparation method of oat fermented drink, comprising the following steps:
[0031] A) mixing the oatmeal and water, followed by boiling, refining and filtering, to obtain the oat filtrate;
[0032] B) mixing the sugar substance with the oat filtrate, followed by homogenization and sterilization, to obtain a feed liquid;
[0033] C) Lactobacillus casei zhang, Lactobacillus plantarum P-8 and Bifidobacterium V9 were inoculated into the feed liquid for fermentation, and after the fermentation was completed, an oat fermented beverage was obtained.
[0034] combine figure 1 The preparation method of the oat fermented drink provided by the invention is described in detail, figure 1 The process flow chart for the preparation of the oat fermented drink provided by the present invention.
[0035] In the present invention, oatmeal and water are firstly mixed, followed by boiling, refining and filtering in order to obtain oat filtrate;
