preparation example Construction

[0031] The invention provides a kind of preparation method of millet germinated brown rice, comprises the following steps:

[0032] 1) The millet brown rice is cleaned with the slightly acidic electrolyzed water of 5-30ppm available chlorine to obtain the cleaned millet brown rice;

[0033] 2) soak the millet brown rice after the cleaning in CaCl 2 In the culture solution for 8-12h, discard the soaking solution, and germinate in the dark for 48-72h;

[0034] 3) The germinated and cultured millet brown rice is subjected to enzyme inactivation and drying treatment to obtain millet germinated brown rice.

[0035] Wherein, the slightly acidic electrolyzed water (SAEW) is also called slightly acidic ionic water, slightly acidic oxidation potential water, the pH value is close to neutral, and the available chlorine is almost entirely composed of hypochlorous acid molecules ( It exists in the form of HClO), and its bactericidal ability is that of hypochlorite (ClO - ) about 100 ti...

Embodiment 1

[0058] The millet is hulled to remove the husk, and the unfulfilled particles are discarded to obtain 1000 g of millet and brown rice. Wash 5 times with slightly acidic electrolyzed water with 15ppm available chlorine and pH 5.8, 3L each time. 3.0mmol / L CaCl prepared from slightly acidic electrolyzed water with available chlorine of 15ppm and pH of 5.8 2 The solution was used as a culture medium, and the washed millet and brown rice were treated with CaCl 2 The culture solution (3 L) was soaked at 34°C for 12 hours, and the culture solution was changed every 2 hours. After soaking, discard the culture solution and culture in a 34°C constant temperature incubator in the dark for 60 hours of germination, during which time the culture solution (800 mL each time) is sprinkled every 12 hours. After the germination is completed, use hot water to kill enzymes, blanching for 5 minutes at a water temperature of 60°C and a material-to-liquid ratio of 1:5, drain the excess water, and d...

Embodiment 2-5

[0072] Examples 2-5 are used to illustrate the influence of culture temperature on GABA in the germination process of millet and brown rice.

[0073] The same method as in Example 1 was used to prepare millet germinated brown rice, the difference being that the temperature of germination cultivation was as shown in Table 2, wherein, germinated at 35°C for 60 hours, the GABA content in millet germinated brown rice was 59.41 mg / 100g; germinated at 40°C for 60 hours , GABA content in millet germinated brown rice is 49.57mg / 100g.

Abstract

The invention relates to a preparation method of millet germinated brown rice rich in gamma-aminobutyric acid. The preparation method comprises the following steps of firstly, hulling millets, removing millet husks, mainlining millet bran and germs to obtain millet brown rice, and cleaning the millet brown rice by subacidity electrolyzed water with available chlorine of 5-300ppm so as to obtain cleaned millet brown rice; 2) soaking the cleaned millet brown rice into a CaCl2 culture liquid for 8-12 hours, removing a soaking liquid, sprouting out of the sun, and culturing for 48-72 hours; and 3) carrying out enzyme deactivation and drying treatment on the millet brown rice after germination culture so as to obtain millet germinated brown rice. The method provided by the invention can be used for effectively controlling the microorganism pollution in the germination process, is high in germination rate and is short in germination time; the enrichment degree of nutritional components in the millet germinated brown rice obtained after germination can reach 126.60mg / 100g, and is a novel functional food and an ideal whole-grain food.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to millet germinated brown rice rich in gamma-aminobutyric acid and a preparation method thereof. Background technique [0002] China is the world's leading producer of millet, and currently ranks first in the world in terms of planting area and output. Millet is the product of millet hulling. Millet brown rice is the remaining whole grain of millet after removing the husk. It is composed of three parts: rice bran, germ and endosperm. It is round in shape and generally slightly darker in color (compared with refined rice) . Although the nutritional value of millet and brown rice is high, rice bran contains a lot of crude fiber, which has poor water absorption and expansion properties, resulting in poor cooking, taste and color of millet and brown rice, which cannot compare with the delicate taste and brightness of refined millet or rice. White appearance competition. These problems r...
