Description

A kind of germinated rice wheat nutrition powder and preparation method thereof

technical field

The invention relates to a germinated rice and wheat nutritional powder and a preparation method thereof, belonging to the technical field of agricultural product processing.

Background technique

Medicine and food are of the same origin, and eating functional foods with health care and disease prevention effects has a significant effect on the prevention and treatment of some chronic diseases, but there are few health foods that people can choose from on the market that can prevent and treat diseases. The traditional dietary customs in my country are mainly plant-based foods. However, with the improvement of living standards, the healthy diet structure is destroyed, and the proportion of people eating cereals and grains is gradually decreasing, leading to eating disorders and poor health. Therefore, the development of Cereals and other health foods have become a trend.

After the seeds germinate, due to various physical and biochemical reactions in the body, the types and contents of functional nutrients in the seeds will increase significantly, and some seeds will taste better after germinating, forming a unique sweet flavor and good taste. Most importantly, some functional factors increase during germination, such as gamma-aminobutyric acid, inositol hexaphosphate, and dietary fiber in germinated brown rice.

On the basis of traditional processing methods, develop emerging food deep processing technologies with physiologically active characteristics, and provide a new generation of functional staple food products, which can not only make up for the lack of nutritional resources in our country, but also create new wealth in the huge market demand. Improve people's quality of life.

Contents of the invention

The object of the present invention is to provide a germinated rice-wheat nutritional powder and a preparation method thereof, the germinated rice-wheat nutritional powder is rich in γ-aminobutyric acid, protein, amino acid, mineral matter, vitamin, dietary fiber, glutathione, oryzanol , carotene, cardiac glycosides and other active substances with special physiological functions, which have many health care functions such as reducing the incidence of cardiovascular and cerebrovascular diseases, preventing gastrointestinal cancer, and anti-aging.

To achieve the above object, the present invention adopts the following technical solutions:

A germinated rice and wheat nutrition powder, the components are calculated by weight percentage: 4-6% of germinated green rice, 3-5% of germinated black rice, 4-7% of germinated red rice, 6-8% of germinated yellow rice, germinated giant embryo Rice 6-8%, germinated rice rich in natural vitamin A 6-8%, germinated high-fiber rice 5-7%, germinated iron-rich rice 4-6%, germinated selenium-rich rice 6-8%, germinated wheat 6- 9%, germinated tartary buckwheat 4-6%, germinated oat 6-8%, germinated barley 4-7%, germinated rye 4-6%, skimmed milk powder 4-7%, maltodextrin 5-8%, oligomer Isomaltose 5-7%, the weight percentage sum of each component is 100%.

The preparation method comprises the following steps:

(1) The green rice, black rice, red rice, yellow rice, giant embryo rice, rice rich in natural vitamin A, high cellulose rice, iron-rich rice and selenium-rich rice are machine-screened to remove empty Shrunken grains and impurities are dried in a drying oven at 45°C for 25 minutes, and after cooling, they are husked with a roughing machine.
