Description

Preparation method of fermented beverage containing rice bran fermentation liquid and blueberry juice
Technical Field
The invention relates to the technical field of beverage processing, in particular to a preparation method of a beverage containing rice bran fermentation liquor and blueberry juice.
Background
The rice bran is a byproduct in the rice processing process, is a substance attached to the surface layer of brown rice after rice husks are removed, mainly comprises rice husks, seed coats, a cross-linking layer and an aleurone layer, and accounts for about 5% of the total amount of the rice. The rice bran contains protein, lipid, mineral substances, dietary fiber, vitamins, oryzanol, ferulic acid and other nutrient components, is known as a "natural nutrient source", and has very high health care and development values.
The rice bran has relatively high glutamate decarboxylase (GAD) activity and can be used for enriching and producing gamma-aminobutyric acid (GABA), and the GABA is approved as a new resource food by the national ministry of health in 2009. GABA is a main inhibitory neurotransmitter in mammals, has various physiological functions such as tranquilizing and allaying excitement, enhancing memory, resisting depression, resisting anxiety, reducing blood pressure, reducing blood sugar and the like, is a precursor for synthesizing nylon 4 and 2-pyrrolidone, and can be widely applied to the fields of medicines, foods, feeds, chemical engineering and the like.
The rice bran has high ferulic acid content, after enzymolysis, carboxyl and hydroxyl of ferulic acid are connected through ester bond to obtain Feruloyl Oligosaccharide (FOs), and rice bran can be fermented by edible fungi to generate feruloyl oligosaccharide. FOs have excellent biological activity and strong inhibitory action on the oxidation of low-density lipoprotein (LDL), and therefore, are expected to be new raw materials for producing drugs for reducing blood fat and preventing arteriosclerosis. FOS can remove free radicals, inhibit lipid oxidation, and relieve oxidative damage, so it can be used as functional food ingredient for health promotion. FOs can promote proliferation of probiotics in vivo, so it can be added into food to enter intestinal tract in the form of food, and improve the ecological environment of microorganisms in intestinal tract. In a word, the application prospect is very wide, and the development space and the market demand are huge.
