Embodiment 1

[0017] The preparation method of germinated brown rice 1

[0018] 1) Take brown rice, wash it with water at 25°C, heat it in acidic hot water at 50°C for 4 minutes, add edible citric acid to the hot water to adjust the pH value to 4;

[0019] 2) Then place the heat-treated brown rice in a germination solution at 25°C and soak for 6 hours. The germination solution is prepared with clean water, and the solution contains 0.03wt% manganese sulfate, 0.03wt% zinc sulfate and 0.05wt% calcium chloride;

[0020] 3) The brown rice soaked in the germination solution is transferred to the germination store for germination, the germination temperature is 28°C, the relative humidity of the germination storehouse is 90%, and the germination time is 22 hours;

[0021] 4) Brown rice is dried after germination. Put the germinated rice in a hot air drying device with a wind speed of 3.5m / s and a wind temperature of 58°C for 6 hours to make the moisture content of the material 12wt%, then cool a...

[0023] The preparation method of germinated brown rice 2

[0024] 1) Take brown rice, wash it with water at 25°C, put it in acidic hot water at 40°C for heat treatment for 6 minutes, add edible citric acid to the hot water to adjust the pH value to 3.5;

[0025] 2) The heat-treated brown rice is then soaked in a germination solution at 30°C for 5 hours. The germination solution is prepared with clean water, and the solution contains 0.02wt% manganese sulfate, 0.05wt% zinc sulfate and 0.03wt% calcium chloride;

[0026] 3) The brown rice soaked in the germination solution is transferred to the germination store for germination, the germination temperature is 35°C, the relative humidity of the germination storehouse is 85%, and the germination time is 18 hours;

[0027] 4) Brown rice is dried after germination. Put the germinated rice in a hot air drying device with a wind speed of 2.5m / s and a wind temperature of 55°C for 7 hours, so that the moisture content of the material is...

Embodiment 3

[0029] Germinated brown rice preparation method 3

[0030] 1) Take brown rice, wash it with water at 25°C, heat it in acidic hot water at 45°C for 5 minutes, add edible citric acid to the hot water to adjust the pH value to 4.5;

[0031] 2) Then place the heat-treated brown rice in a germination solution at 28°C and soak for 7 hours. The germination solution is prepared with clean water, and the solution contains 0.01wt% manganese sulfate, 0.04wt% zinc sulfate and 0.04wt% calcium chloride;

[0032] 3) The brown rice soaked in the germination solution is transferred to the germination warehouse for germination. The germination temperature is 25°C, the relative humidity of the germination warehouse is 95%, and the germination time is 24 hours;

[0033] 4) Brown rice is dried after germination. Put the germinated rice in a hot air drying device with a wind speed of 4 m / s and a wind temperature of 65°C for 5 hours, so that the moisture content of the material is 11wt%, then coole...

Abstract

The invention discloses a method for preparing germinated brown rice. The method comprises the following steps of: 1) cleaning brown rice serving as a raw material with water, and performing heat treatment on the cleaned brown rice in hot water at the temperature of between 25 and 30DEG C and the pH value of 3.5-4.5 for 3 to 6 minutes; 2) soaking the brown rice subjected to heat treatment in a germination accelerating solution at the temperature of between 25 and 30DEG C for 5 to 7 hours, wherein the germination accelerating solution is prepared from water, and contains 0.01 to 0.03 weight percent manganese sulfate, 0.03 to 0.05 weight percent zinc sulfate and 0.03 to 0.05 weight percent calcium chloride; 3) transferring the soaked brown rice into a germination library for germination; and 4) drying the germinated brown rice to obtain the germinated brown rice product. By the method, the brown rice germination time can be shortened by about 6 hours, the germination percentage is improved by about 8 percent compared with that of the traditional method, the content of GABA (gamma-aminobutyric acid) and reducing sugar in the germinated brown rice is improved, the quality of the product is high, and the edible safety is obviously improved.

Description

technical field [0001] The invention belongs to the field of food processing and relates to a preparation method of germinated brown rice. Background technique [0002] In the prior art, the processing technology of germinated brown rice is cleaning, soaking in clear water, germination, and hot air drying. The disadvantage of this processing method is that brown rice undergoes a long time (26-32 hours) germination process, the production efficiency is low, the loss of nutrients is large, and the product is easily contaminated by microorganisms, which reduces the quality of the product. Contents of the invention [0003] In order to solve the deficiencies in the prior art, the invention provides a method for preparing germinated brown rice with short germination time, high germination rate and less nutritional loss. [0004] The technical scheme adopted in the present invention is: [0005] A preparation method of germinated brown rice, comprising the steps of: [0006] ...
