Embodiment Construction
[0011] 1. Raw material screening: Raw material Z601 undergoes density screening and winnowing steps to select plump rice grains.
[0012] 2. Make brown rice: peel the screened rice grains to make clean brown rice.
[0013] 3. Grinding into polished rice: Use a small rice polishing machine to grind for 30 seconds to make polished rice with embryos.
[0014] 4. Germination: Transfer the polished rice with embryos into a germination machine, soak at a constant temperature of 29-32°C, and cultivate for 11-14 hours.
[0015] 5. Drying: After germination, put the germinated rice grains into an oven at 52-57°C to terminate the activity, and detect the GABA content by HPLC.

The invention discloses a processing technology of germ-remained polished rice with a high yield of gamma-amino butyric acid (GABA). The processing technology comprises the following steps: taking rice Z601 as the raw material, grinding the rice Z601 in a rice polishing machine for 30 seconds to obtain polished rice with a germ remained rate of 80% or more, then transferring the polished rice to a cultivating device, soaking polished rice at a constant temperature of 29 to 32 DEG C, carrying out germination for 11 to 14 hours, after germination, placing the culture dish in a baking oven with a temperature of 52 to 57 DEG C to terminate the activity, and carrying out HPLC detection, wherein the HPLC detection results show that after the germination, the content of GABA in polished rice is increased to 31.13 mg / 100g. By improving the germ remained rate of polished rice, the nutritional value of rice is increased. The processing has the following advantages: (1) the germ remained rate is improved, and the rice yield is increased; (2) the rice is rich in nutrients and has a good taste; (3) the GABA content is high, and can reach about 31.13 mg / 100g.
Description
Technical field [0001] The patent of the present invention relates to the field of grain processing, especially the processing technology of high-nutrition polished rice with retained embryos. Background technique [0002] Existing rice processing technology is divided into two kinds: (1) improve the precision of rice by grinding away most or all embryos, although its mouthfeel of polished rice produced by this method can meet people's needs, but can not be very good (2) By reducing the degree of grinding, the integrity of the embryo is kept as much as possible, but the rice produced by this method has too much seed coat, although the nutrition can meet people's needs, but the taste is poor. Can not meet people's needs. The embryo is the place with the strongest physiological activity of the grain, and its mass accounts for 3% of the whole rice grain, but it is the most nutritious part of the rice, which is rich in protein, fatty acid, vitamin and soluble sugar. Therefore,...
