Problems solved by technology

Since most of the bacteria are on the surface of the grain, the post-harvest sterilization treatment is considered to be the most helpful for the control of microorganisms, but the existing research has not found a simple and easy method to inhibit the contamination microorganisms, and the general fungicides are commonly used Sodium hypochlorite, electro-generated acidic water, electro-generated alkaline water, Ca 2+ processing, or Ca 2+ Combined treatment with gibberellin, but the fresh-keeping effect is relatively simple, and it cannot comprehensively inhibit the degradation and loss of various nutrients in germinated brown rice

Embodiment 1

[0021] (1) In terms of parts by weight, take 100 parts of water, add 5 parts of malic acid, 3 parts of chlorogenic acid and 4 parts of zinc lactate in sequence, stir evenly until completely dissolved, and obtain a nutrient solution; (2) Adopt atomization method, Spray the nutrient solution evenly on the surface of the brown rice until the moisture content of the rice grains is 16%, and the addition rate is 0.4% / h; (3) Continue to spray the nutrient solution on the surface of the brown rice at a speed of 0.8% / h by atomization, Until the moisture content of the rice grains is 21%; (4) Place the rice grains under a pulsed electric field for 7 hours, the electric field strength is 105kV / m, the pulse width is 80ms, the pulse frequency is 2Hz, and the direction of the field strength is vertically downward; (5) Use Atomization method, replenish nutrient solution on the surface of rice grains at a rate of 0.6% / h, until the moisture content of rice grains reaches 21%, and leave for 3 ho...

Embodiment 2

[0023] (1) Compound malic acid, chlorogenic acid and zinc lactate (see Table 1 for the components and ratios), stir evenly until completely dissolved, and obtain the nutrient solution; (2) Use the atomization method to spray the nutrient solution evenly Apply on the surface of brown rice until the moisture content of rice grains is 17%, and the adding speed is 0.5% / h; (3) Use atomization method, continue to spray the nutrient solution on the surface of brown rice at a speed of 0.9% / h, until the moisture content of rice grains is 23%; (4) Place the rice grains in a pulsed electric field for 8 hours, the electric field strength is 110kV / m, the pulse width is 80ms, the pulse frequency is 3Hz, and the direction of the field strength is vertically downward; (5) The atomization method is used to Supplement the nutrient solution on the surface of the rice grains at a rate of 0.7% / h until the moisture content of the rice grains is 23%, and leave it for 4 hours; (6) Place the rice grain...

Abstract

The invention relates to a method for producing germinated brown rice by adding a trace amount of nutrient solution. The method is characterized by comprising the following steps: spraying the nutrient solution which contains components such as malic acid, chlorogenic acid and zinc lactate in an atomizing manner until the water content of brown rice is 21-23 percent; then treating the brown rice under a pulse electric field; continuously supplementing the nutrient solution twice, and continuously treating the brown rice under the pulse electric field twice until the water content of rice grains is 13-15 percent to obtain the germinated brown rice with high nutritive value and stable quality. By adding the trace amount of nutrient solution and treating the brown rice under the pulse electric field, the bud growth can be quickly accelerated, and meanwhile, the bacterial growth is suppressed. The method is compact, continuous, and simple and easy to operate.

Description

technical field [0001] The invention relates to a method for producing germinated brown rice by adding a small amount of nutrient solution, and belongs to the field of food processing. Background technique [0002] Germinated brown rice is a brown rice product composed of young sprouts, bran layer and endosperm obtained by germinating brown rice to a certain bud length through physiological activation process as raw material. Germinated brown rice retains more than 60% of the important nutrients of rice, and its nutritional value is more than ten times that of ordinary white rice. Especially after germination, some active substances with special physiological functions such as γ-aminobutyric acid, glutathione, γ- Oryzanol, ferulic acid, etc. increased significantly. [0003] However, during the germination process of brown rice, due to the high water content and suitable ambient temperature and humidity conditions, microorganisms are easy to multiply in large numbers, which...
