Description
Technical Field
The invention relates to the technical field of rice deep processing, in particular to rice cadmium-removing processing equipment.
Background
As a main producing country of rice in China, the rice yield accounts for about 30% of the total global yield, and according to incomplete statistics, more than 60% of people in China use rice as staple food. With the rapid development of modern industry, heavy metal cadmium invades rice through polluted soil, the pollution problem of cadmium in rice becomes more serious day by day, and the cadmium is one of the major food safety problems facing the world. Investigation and analysis of rice in pollution areas and markets in Hunan province by thunder (2010) show that 36% of rice samples have cadmium exceeding conditions; 2010 reports that cultivated land of China 1/5 is polluted by heavy metal cadmium, and relates to 25 areas of 11 provinces, mainly areas of south of the Yangtze river such as Hunan and Jiangxi. Heavy metal cadmium is a food pollutant which is determined by the world health organization to be a priority study, rice has strong enrichment capacity on cadmium, the heavy metal cadmium can be accumulated in a human body through a food chain, and long-term accumulation can cause certain damage to liver and kidney, reproductive system, hoof forming tissue and the like, even generate 'three-cause effect', so the study on how to remove the heavy metal cadmium in the rice needs to be solved urgently.
At present, reports and technical achievements about treatment of heavy metal cadmium pollution in rice are quite numerous, but the main focus is on the processing technology of rice, such as soaking, cooking, rice hulling, rice milling, extraction of rice starch, extraction of rice protein and the like. Because heavy metal cadmium is mainly concentrated in rice endosperm, the rice hulling and milling method has no obvious cadmium removal effect; the fact that the leaching amount of cadmium is increased when the soaking temperature of the Liu crystal (2013) is increased in the rice soaking process is found, but the cadmium removal rate is only 33.71% when the rice is soaked for 30 hours at 30 ℃, and the soaking effect of water has a certain effect on removing cadmium in the rice, but the effect is not obvious. Some scholars prove that the cadmium content in the rice can be reduced to a certain extent by heating treatment through tests, but the cadmium removal rate is low; the rice starch product is extracted by the field sun (2013) by an alkaline process, under the optimal process condition, the removal rate of cadmium can reach 84.77%, but the starch product prepared by the method has larger quality difference with the original starch and lower starch extraction rate.
