Production method of rice product rich in gamma-aminobutyric acid

Abstract

A production method of a rice product rich in gamma-aminobutyric acid comprises the following steps: separating new harvested rice husks and husked rice to obtain a raw material brown rice, disinfecting the raw material brown rice by using a 0.05% sodium hypochlorite solution, and cleaning the sodium hypochlorite residual component by using tap water; immersing the raw material brown rice in a calcium chloride solution with the concentration of 0.2% at 30DEG C for 6h according to a volume ratio of 4:1, cleaning by using tap water, spreading the immersed and cleaned raw material brown rice on a mesh disc or a mesh belt capable of draining water, sending the obtained raw material brown rice to a culture chamber, and culturing at 30DEG C for 48h under a relative humidity in the chamber of 90-99% for germinating in order to obtain germinated brown rice; and carrying out high-temperature and high-humidity segmented drying on the obtained germinated brown rice, and polishing to obtain polished rice or crushing and sieving to obtain germinated brown rice flour or adding water and crushing to obtain a germinated brown rice slurry. Rice is processed to produce the raw material brown rice, and a bioconversion technology is used to produce the rice product with high content of nutrition.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a production method for producing rice products rich in r-aminobutyric acid (GABA) by using germinated rice. Background technique [0002] my country is a big rice production and consumption country in the world. Traditionally processed ordinary brown rice is rich in nutrition, but it cannot be accepted by people for a long time due to its poor taste and digestion and absorption rate. With the improvement of rice processing level, people eat white rice as staple food, but its More than 60% of the nutrients of the original rice are lost. With the improvement of people's living standards and changes in consumption concepts, consumers not only require rice to have good eating quality, but also pay more attention to the nutritional value and health care function of rice. Germinated rice is an upgraded product of rice. On the basis of retaining the rich nutrients of brown rice...
