Embodiment 1

[0060] Embodiment 1: the production of the rice flake of high gamma-aminobutyric acid (GABA)

[0061] 181 rice varieties collected from rice-producing areas around China, these varieties belong to early indica, early japonica, middle indica and other rice types, after three rounds of screening tests, screened out high glutamic acid decarboxylase activity, γ-aminobutyric acid Early indica rice variety Zao 944 with high enrichment amount, Zaoyin No. 1 variety and other rice varieties suitable for making the functional rice products with high γ-aminobutyric acid content of the present invention, and the related varieties of medium indica rice and early japonica rice were carried out at the same time. test, thereby completing the present invention.

[0062] The production method of high gamma-aminobutyric acid rice flakes is as follows;

[0063] (1) Select the newly harvested early indica rice (the variety is Zao 944, a commercial variety sold publicly), and separate the husked a...

Embodiment 2

[0068] Example 2: Functional nutritional rice flakes with high gamma-aminobutyric acid (GABA) content

[0069] According to the steps described in Example 1, in this example, the specific consumption of each raw material is: raw material brown rice: 100kg; L-monosodium glutamate: 0.65kg; calcium lactate: 0.10kg; pyridoxal phosphate: 0.04 kg. The variety used was Early 944 (a commercial variety sold publicly).

Embodiment 3

[0070] Example 3: Functional nutritional rice flakes with high gamma-aminobutyric acid (GABA) content

[0071] According to the steps described in Example 1, in this example, the specific consumption of each raw material is: raw material brown rice: 100kg; L-monosodium glutamate: 0.93kg; calcium lactate: 0.03kg; pyridoxal phosphate: 0.03 kg. The variety used was Early 944 (a commercial variety sold publicly).

Abstract

The invention belongs to the technical field of rice deep processing, in particular to a production method of a functional rice product which has a special sweet flavor and is rich in Gamma-aminobutyric acid and a product thereof, the rice product is produced by virtue of the activities of high glutamate decarboxylase, amylase and protease in germinated brown rice of an indica type rice or a non glutinous rice. The invention takes the indica type rice or the non glutinous brown rice as a raw material which carries out the steps of cleaning, disinfection, soaking, germination, cleaning, beating into rice milk, heat insulation, transformation, drum drying or spray drying, and the like, to be produced into functional nutrition rice flake or rice powder which is rich in Gamma-aminobutyric acid. Compared with the prior art, the rice product makes full use of the activities of the glutamate decarboxylase, the amylase and the protease in the germinated brown rice; the produced rice product has the special sweet flavor; by calculating based on dry basis, the content of Gamma-aminobutyric acid is high (1,000-1,400mg/100g), and the nutritional value and the digestibility are high. The rice product of the invention can be taken as the functional food for resisting fatigue and reducing blood lipid.

Description

technical field [0001] The invention belongs to the technical field of deep processing of rice, and specifically relates to a kind of germinated brown rice with special sweet aroma and high gamma-aminobutyric acid by utilizing the high glutamic acid decarboxylase, amylase and protease activities in early indica rice, middle indica rice or early japonica germinated brown rice Functional rice products and methods for their production. Background technique [0002] my country is a big rice producing and consuming country in the world. The annual output of rice in my country is about 180 million tons, of which the annual output of early indica rice is about 32 million tons, accounting for about 17.78% of the total rice output. 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. Early indica rice is...
