Problems solved by technology

The finer the grain processing, the greater the loss of nutrients. The nutritional value of brown rice is several times or even dozens of times higher than that of polished rice, but its taste is relatively poor, which is incompatible with the color, aroma and taste of contemporary people's dietary requirements, thus affecting The consumption of brown rice also poses a great threat to people's health. With the gradual improvement of living standards, the "three high" crowd is gradually expanding, which is directly related to people's daily eating habits and dietary structure.

Abstract

The invention provides a preparation method of probiotic fermented rice milk. Three probiotics of lactobacillus rhamnosus, lactobacillus paracasei subsp. paracasei, and lactobacillus brevis are used as original strains, and compound probiotic freeze-dried powder is obtained through amplification culture, powdery freeze-dried strain preparation, and freeze-dried powder complex formulation. The probiotic fermented rice milk is prepared by the following steps: obtaining rice, brown rice and drinking water according to a weight ratio of 2:1:7, performing pulp refining in a colloid mill, sieving by a 80-mesh fine sieve to prepare mixed rice milk pulp, adding 5% white sugar, performing liquefaction by high temperature resistant alpha-amylase, performing saccharification by glucoamylase, performing hydrolyzation by papain, inoculating the compound probiotic freeze-dried powder according to a ratio of 0.01%, allowing the powder to stand and performing fermentation for 4 hours, well mixing, and performing aseptic filling.

Description

(1) Technical field [0001] The invention relates to a preparation method of probiotic fermented rice milk, in particular to an enzymatic method for preparing mixed saccharification slurry of rice and brown rice, and then fermenting with compound probiotics to prepare fermented rice milk, which belongs to the field of bioengineering. (2) Background technology [0002] From an agricultural point of view, deep processing, comprehensive utilization of agricultural products, especially bulk grain agricultural products, and increasing added value are currently important topics for the government, farmers, enterprises and research institutes. Taking the bulk agricultural product—grain as the processing object, processing the grain into liquefied food whose appearance, taste, and nutrition meet the technical indicators of similar foreign products will greatly increase the consumption speed of grain food, improve people's nutritional intake structure, and increase The added value of g...
