Description

Semi-coarse rice and processing method thereof
Technical Field
The invention relates to a semi-coarse grain and a processing method thereof, in particular to semi-coarse rice and a processing method thereof.
Background
With the improvement of living standard of people, the whole grain brown rice is widely concerned because the brown rice contains rich nutrient components and physiological active substances.
The brown rice is whole grain rice obtained by unshelling rice and then performing no processing or less processing, and is composed of three major parts of rice bran, embryo and endosperm. Compared with the white rice, the brown rice realizes the full-nutrition retention of the rice to a higher degree.
Because the brown rice is rice grains with the skin layer and the embryo still remained after the rice husking, compared with the rice, the brown rice not only contains more nutritional ingredients such as protein, fat, vitamins, mineral substances and the like, but also contains various functional factors for promoting the health of human bodies such as dietary fiber, oryzanol, glutathione, gamma-aminobutyric acid, rice bran polysaccharide, octacosanol, inositol and the like.
However, because the brown rice bran layer has high content of crude fiber and compact texture, water is not easy to enter the inside of endosperm during direct cooking, starch in the endosperm is not easy to be gelatinized, and the palatability, the cooking property and the digestibility are poor. The problems of difficult water absorption, time-consuming cooking and the like caused by the compact rice bran layer make the texture and taste quality of the rice difficult to accept and eat directly, so more active attempts and exploration are needed, and the eating quality of the brown rice is improved by a better technical method so as to produce the edible brown rice capable of meeting the consumption requirements of people.
Disclosure of Invention
The invention aims to provide a simple and easily-realized method for processing semi-brown rice, balance nutrition and taste between brown rice and white rice and solve the existing problems.
In order to achieve the above object, the present invention provides a method for processing semi-brown rice, wherein the method comprises the steps of: step 1, selecting raw materials and removing impurities; step 2, husking the grains, and screening to obtain brown rice; step 3, pretreating the brown rice; step 4, lightly grinding the treated brown rice to obtain semi-brown rice; and 5, color selection and packaging.
The processing method of the semi-rough rice comprises the following steps of 1, screening good rice varieties with long growth periods, harvesting, threshing by a threshing machine, removing sand and stone impurities, and obtaining grains.
In the above processing method of semi-brown rice, the rice grains are hulled by using a rice huller in the step 2, and the hulled brown rice mixed with part of the rice hulls and the hulled grains is screened by a screen to obtain brown rice.
In the above processing method of the semi-brown rice, in the step 3, the brown rice is treated with steam, cooled and refrigerated, and then dried.
The processing method of the semi-brown rice comprises the following steps of 3, uniformly spreading the brown rice in a steam box, wherein the spreading thickness is 3-5 cm, introducing water vapor with the pressure of 0.1MPa for 4-6 min, taking out the brown rice, refrigerating at-15-0 ℃ for 8-10 min, taking out the brown rice, drying in a hot air dryer, and enabling the water content after drying to be equal to or lower than 10%.
In the step 4, the rice mill is adopted to lightly mill the treated brown rice for 8-10 seconds to obtain the semi-brown rice with visible black abdominal furrows and retained activity of partial rice embryos and seeds.
The processing method of the semi-rough rice comprises the following steps of selecting the semi-rough rice in color by using a color selector in the step 5, and finally packaging.
The invention also provides the half-brown rice processed by the method.
The semi-rough rice and the processing method thereof provided by the invention have the following advantages:
the processing technology of the invention effectively reduces the loss of rice by less grinding and light grinding, thereby saving the cost. The method partially retains rice embryo and partially has seed activity, thereby ensuring original nutrition of rice. The obtained semi-brown rice has no excessive processing, so that the original color and taste of rice are ensured, and the nutrition and taste are balanced between brown rice and white rice.
Detailed Description
