Embodiment 1

[0019] Embodiment 1: Fresh paddy hulling, lightly milled by a germ-preserving rice milling unit, color sorting and grading by a color sorter to obtain refined white germ-preserving rice, wherein the germ-preserving rice milling machine and the color sorting machine can use existing technical equipment; Wash the refined white germ-preserved rice, immerse it in an ozone aqueous solution with a concentration of 1.0 mg / kg for 2 to 5 minutes, drain the water, and then use a sodium ascorbate solution containing 2% chitosan and 0.2% (1% acetic acid as a solvent) Soak for 2 minutes and dry in natural airflow to form a transparent and bright protective film. Soak the film-coated raw materials in clean water for 24 hours, and then cultivate them at 25°C for about 24 hours to form germinated rice with a bud length of 0.5-1.0 mm. The germinated rice is dried at a low temperature of 50-60°C to obtain dry germinated rice. Polished rice.

Embodiment 2

[0020] Example 2: The fresh rice is hulled, lightly milled by a germ-preserving rice milling unit, and color sorted by a color sorter to obtain refined white germ-preserving rice. Get the refined white germ-preserved rice and clean it, immerse it in the ozone aqueous solution with a concentration of 1.5mg / kg for 2 to 5 minutes, drain the water, then use 1% chitosan and 0.1% sodium ascorbate solution (3% acetic acid as solvent) ) spraying, drying in airflow at 45-50°C to form a transparent and bright protective film. Soak the film-coated raw material in an aqueous solution containing 0.01% gibberellin for 24 hours, and then culture it at 25°C for about 24 hours to form germinated rice with a bud length of 0.5-1.0 mm. The germinated rice is germinated at a temperature of 50-60°C. Low-temperature drying obtains dry germinated polished white rice.

Abstract

The invention provides a production method of germinated milled rice, comprising the following steps: adopting milled germ-retaining rice that is produced by a special process as germinating materials, sterilizing the milled germ-retaining rice in water solution with the ozone concentration of 1.0-1.5mg / kg, coating by 1-2 percent of chitosan solution, soaking in clear water or 0.005-0.015 percent of gibberellin for 20-30 hours, culturing in the situation of 20-30 DEG C, and drying at 50-60 DEG C when the length of germs of germinated rice is 0.5-1.0 mm to obtain the germinated milled rice. In the production method, the germination ratio is more than 95 percent, Gamma-aminobutyric acid is more than 60mg every 100g of germinated rice, and the water content is 12-15 percent. The invention has simple process, reduces the microbial contamination in the germinating process and solves the difficult problems of brown stains, cracking, and the like in the drying process; and the germinated milled rice obtained by the method is better than germinated brown rice and milled germ-retaining rice on the taste, and has good colors, rich nutriments and strong heath care function.

Description

technical field [0001] The invention relates to a production method of germinated polished white rice. Background technique [0002] Germinated polished white rice has both the taste of polished white rice and the health care function of germinated brown rice; the superior physiological functions of germinated polished white rice include: (1) Germinated polished white rice is processed from refined white germ-preserved rice, which retains the nutritional content of the germ (2) Rich in γ-aminobutyric acid (GABA), the GABA has the functions of activating cerebral blood flow, enhancing brain cell metabolism, lowering blood pressure, anticonvulsant, promoting long-term memory, improving liver and kidney function, relieving arteriosclerosis, reducing (3) Rich in inositol hexaphosphate (IP-6) and glutathione, which have strong antioxidant capacity and fatigue-relieving effects; (4) Rich in anti-lipid oxidation substances ( Germinated brown rice is rich in anti-lipid oxidation su...
