Production process of cadmium-free germinated brown rice

Abstract

The invention discloses a production technology of cadmium-free germinated brown rice. The production technology comprises the following steps of taking brown rice of which the cadmium content is 0.2-1.0mg / kg, cleaning the taken brown rice, disinfecting the cleaned brown rice, placing the disinfected brown rice in a first compounding cadmium-free solution of which the pH is 3.5-4.5, and soaking the disinfected brown rice in the first compounding cadmium-free solution for 20-28h; then performing separation so as to obtain soaked brown rice, and placing the soaked brown rice in a second compounding cadmium-free solution of which the PH is 4.5-5.5 until the brown rice is completely immersed; performing first germination acceleration for 50-70h, and then taking out the brown rice after the first germination acceleration; and then adding distilled water until the brown rice is completely immersed, performing second germination acceleration for 10-15h, then taking out the brown rice after the second germination acceleration, performing inactivation, and performing drying so as to obtain the cadmium-free germinated brown rice. According to the production technology disclosed by the invention, a cadmium-free technique and a production technique of the germinated brown rice are combined, edible cadmium-free solvents are added, and the germinated brown rice is produced, so that the cadmium content of the cadmium-containing brown rice can be obviously reduced, besides, the cadmium-free germinated brown rice and conventional germinated brown rice do not have significant differences in the gamma-aminobutyric acid content, and the production technology has the advantages of being simple to operate, significant in cadmium-free effects and low in cost.

Description

technical field [0001] The invention relates to the treatment technology of cadmium polluted rice. More specifically, the present invention relates to a production process of cadmium-free germinated brown rice. Background technique [0002] Due to factors such as industrial emissions and farmland fertilization, the problem of heavy metal pollution in farmland soil in my country has gradually intensified, and the phenomenon of rice cadmium exceeding the standard has occurred from time to time. Surveys show that about 10% of rice in my country has excessive cadmium. At present, the methods to deal with excessive cadmium in rice mainly include soil remediation and screening of rice varieties with low enrichment capacity, but both methods require a certain period of treatment. During the treatment process, a large amount of cadmium-exceeding rice is still produced every year. On the one hand, it causes food waste, and on the other hand, it also has the risk of flowing into the...
