Problems solved by technology

[0004] However, brown rice is easy to rot and deteriorate due to its own metabolism and the microbial reproduction attached to the surface of rice grains in the germination process, and produces fermentation odor and stench, which seriously affects the quality of germinated brown rice.
At present, in order to avoid these problems, chemical methods such as adding acid, ozone or hypochlorous acid to the soaking solution are mainly used, but these methods are likely to cause secondary pollution of the product, increase the processing cost of the enterprise and reduce the product quality.

Embodiment 1

[0023] Example 1 (optimal solution): 100 g of brown rice after impurity removal, rinsed with distilled water, drained; placed in a pulsed strong light device, with a flash frequency of 50 n / s, a flash interval of 3 s, and an input Under the conditions of voltage 500v and pulse width 500μs, irradiate for 8 minutes; then soak in 2000mL soaking solution with a temperature of 28°C and a Ph of 5.5 for 8h; Drench once, passivate after the brown rice germinates to a certain length (0.5~1.0mm), and the germination rate reaches 98% at this time; finally, dry it with hot air at 60°C to make the moisture of the germinated brown rice 10%; finally divide into bags Vacuum packing is enough.

Embodiment 2

[0025] 100g of brown rice after impurity removal, rinsed with distilled water, and drained; placed in a pulsed strong light device, under the condition that the number of flashes is 30n / s, the interval between flashes is 5s, the input voltage is 3000v, and the pulse width is 200μs Irradiate under the same conditions for 5 minutes; then soak in 2000mL distilled water at 20°C for 10h; then germinate at 30°C in the dark for 24h, spray once every 2h during the period, and wait for the brown rice to germinate to a certain length (0.5~1.0mm ) after passivation, and the germination rate reaches 93% at this time; finally, it is dried with hot air at 60°C, so that the moisture content of the germinated brown rice is 14%, and then vacuum-packed in separate bags.

Embodiment 3

[0026] Example 3: 100g of brown rice after impurity removal, rinsed with distilled water, drained; placed in a pulsed strong light device, with a flash frequency of 40n / s, a flash interval of 0s, an input voltage of 2000v, and a pulsating Irradiate for 3 minutes under the condition of a width of 100 μs; then soak in 2000 mL of weakly acidic soaking solution with a temperature of 25 ° C and a pH of 6 for 6 h; After the brown rice germinates to a certain length (0.5~1.0mm), passivation is carried out, and the germination rate reaches 88% at this time; finally, it is dried with hot air at 60°C so that the moisture content of the germinated brown rice is 12%, and then vacuum-packed in bags.

Abstract

The invention relates to a preparation method of germinated brown rice, and in particular relates to a method for preparing germinated brown rice by intensive pulse light. The preparation method has the main technical characteristics that the processing process comprises the following steps: eliminating impurities, cleaning, draining, pre-processing in an intensive pulse light device, dipping in a neutral or acidulous soak solution, causing rice grains to sprout under the condition of keeping out of the sun, passivating, drying, and vacuum packaging in different bags. The invention provides apreparation method of germinated brown rice, which has short processing flow and simple and easy technical process. In the method, no chemical bactericides are added, thereby avoiding secondary pollution of the germinated brown rice, reducing environmental pollution, and extremely lowering influence on the internal quality of the germinated brown rice in the processing process. The prepared germinated brown rice is easy to boil and adsorb, has good taste, combines various edible advantages of various types of germinated brown rice in the market and is an ideal principal food product for people.

Description

technical field [0001] The invention relates to a method for preparing germinated brown rice, in particular to a method for preparing germinated brown rice by using pulsed strong light. Background technique [0002] Brown rice is a product composed of bran layer, germ and endosperm after rice husking. It has very high nutritional value and is called longevity rice by developed countries. However, the periphery of brown rice is wrapped by fibrous tissue, and its water absorption and swelling properties are all poor, resulting in bad taste of brown rice, long cooking time, and difficult to digest and absorb. Therefore, it is necessary to improve the eating quality of brown rice. [0003] According to scientific reports, germination of brown rice can not only make up for the above-mentioned defects, but also effectively improve the nutritional value and physiological functions of brown rice. Germinated brown rice is the product obtained by cultivating brown rice at a certain ...
