Method for preparing germinated brown rice milk beverage by compound lactobacillus fermentation

Abstract

The invention provides a method for preparing germinated brown rice milk beverage by compound lactobacillus fermentation, which comprises the following steps of: preparing four lactobacillus direct-throwing fermentation agents such as lactobacillus rhamnosus, pediococcus acidilactici, streptococcus thermophilus and lactobacillus brevis; then soaking brown rice for 10 hours at 30 DEG C, and germinating for 12 hours at 2 DEG C to prepare germinated brown rice; adding 3 times water into the germinated brown rice, grinding milk by adopting colloid, gelatinizing and saccharifying the milk, adding 150 grams of direct-throwing fermentation agents into each ton of liquid rice milk, and performing standing fermentation for 6 hours at the temperature of between 38 and 40 DEG C; and centrifuging the liquid rice milk at 5,000 revolutions per minute, removing residue, adding xylitol according to the clear liquid volume for blending, filtering the liquid by using a hollow fiber membrane, performing ultrahigh-temperature instantaneous sterilization for 2 seconds at 143 DEG C, and filling the liquid with pillow-type package or tetra package to obtain a finished product.

Description

(1) Technical field [0001] The invention relates to a method for preparing a brown rice milk drink fermented and germinated by compound lactic acid bacteria, in particular to a method for preparing a functional drink by using two strains of lactic acid bacteria to ferment and germinate brown rice milk, which belongs to the field of bioengineering. (2) Background technology [0002] Germinated brown rice contains 100-150mg / 100g of γ-aminobutyric acid, which is twice that of brown rice and nine times that of rice. γ-aminobutyric acid is a kind of protein, which exists in the brain and bone marrow of mammals, and is contained in vegetarian dishes and fruits, but the content is scarce, and people rely on natural food intake to supplement it. γ-aminobutyric acid can be used to improve the blood flow of the brain, increase the supply of oxygen, improve the metabolism of the brain, and help treat headaches, tinnitus, and confusion caused by stroke, head trauma sequelae, cerebral ar...

Problems solved by technology

Brown rice contains a variety of vitamins, dietary fiber and other nutrients, but because of its poor taste, people basically do not eat brown rice directly, but use it as food raw materials, mostly used for wine making and puffed food
