Description

Technical Field

[0001] The invention relates to the technical field of nutritious rice flour, in particular to a method for preparing germinated nutritious rice and nutritious rice flour. Background Art

[0002] Sprouted brown rice is made from brown rice, which is processed by physiological activation technology and then germinated. It avoids the shortcomings of brown rice such as steaming, poor taste and absorbability. The bran fiber of germinated brown rice is softened, part of the protein is decomposed into amino acids, and starch is decomposed into sugars, which improves the sensory properties and flavor of food. Compared with brown rice, the types and contents of functional ingredients in germinated brown rice are richer. Generally, the content of γ-aminobutyric acid in germinated brown rice is about 10 times that of ordinary rice; the content of inositol hexaphosphate is more than 4 times that of white rice, and the dietary fiber is 3.7 times that of polished white rice. In addition, germinated brown rice is also rich in glutathione, ferulic acid, phytic acid, oryzanol, tocotrienol, phytosterols, tetracosanol, octacosanol and other active substances with special physiological functions, which have many health functions such as reducing the incidence of cardiovascular and cerebrovascular diseases, preventing digestive tract cancer, and anti-aging. Parboiled rice has a high content of nutrients that are beneficial to the human body. For example, the content of vitamin B1 and vitamin B2 in parboiled rice is almost 3 to 4 times that of ordinary rice, the content of crude fat is 1 to 2 times that of ordinary rice, the content of protein is also much higher than that of ordinary rice, and the content of elements such as Ca, P, and Fe is almost 2 to 3 times that of ordinary rice. The reason may be that some water-soluble nutrients in the rice will diffuse into the soaking liquid during the soaking process, and then enter the endosperm of the rice as the soaking time increases. These substances are retained when they are processed into rice, thereby increasing the nutritional content. Soaking can not only increase the content of water-soluble nutrients, but also improve the color of parboiled rice and reduce the content of heavy metals in parboiled rice by soaking in different soaking liquids. In addition, after a series of hydrothermal treatments, the nutrients in parboiled rice can be more easily absorbed by the human body, and the rice yield is high during steaming, the expansion is good, the rice grains are not sticky, and it has a special aroma and is easy to digest.

[0003] Since germinated brown rice has high nutritional value, many companies have launched commercialized germinated brown rice. The process technology used is basically traditional technology, including rice to husking rice (brown rice), soaking, germination, drying process, and parboiled rice process is rice, soaking, drying, and rice milling. Germinated brown rice is made from brown rice, which is made from rice. In the process of preparing germinated brown rice from rice, due to mechanical damage to the endosperm and bran fiber membrane, part of the brown rice loses its germination ability. In addition, during the soaking and germination process, nutrients penetrate into the soaking liquid through the bran fiber layer, causing nutritional loss, and producing odor, which has an adverse effect on the germinated brown rice, and consumes a lot of water. Summary of the invention

[0004] In view of this, the present invention provides a method for preparing sprouted nutritious rice and nutritious rice flour. The sprouted nutritious rice is prepared by using the special sprouted nutritious rice production device of the present invention, and nutrients are added to the sprouted nutritious rice, and nutritious rice flour is obtained after grinding, screening and drying.
