Description
Technical field
The invention belongs to technical field of grain deep processing, especially relate to a kind of processing method reducing content of beary metal in ground rice, rice gluten powder.
Background technology
China is the large paddy rice producing country of the first in the world, within 2008, rice yield is at 1.89 hundred million tons, paddy is the first cereal crops of China, but, the soil quality direct relation of various places the quality of edible rice, but rice is obviously better than other the crop varieties such as corn, soybean for the suction-operated of heavy metal pollution.Therefore, by deep processing means, rice is processed, while removing heavy metal, obtain quality product, too increase the added value that rice utilizes.
Heavy metal in rice mainly combines with Chelating state and amino acid, and to it is reported in plant that the main and metallothionein of heavy metal forms ligand and combines, some is combined with the ligand containing O/N.Metal is dissolvable in water in acid solution, and excessive strong acid can destroy rice Middle nutrition composition, and, it is reported that acid is relevant with acidity for the removal effect of heavy metal, but depend on the complexing power of acid group more.
The patent of invention of CN201310140019.1 discloses a kind of de-cadmium rice protein and its preparation method and application, its key step is take rice as raw material, rice residue is obtained except after desizing with alpha-amylase, then, de-Cadmium treated is carried out with acid solution, used acid is the one in food-grade acetic acid, citric acid, malic acid, lactic acid, tartaric acid, oxalic acid, phosphoric acid, and addition is that rice residue mixes by 1:2-5 weight ratio with acid solution, and in this step, the effect of adjust ph is only played in acid; Comparatively large by acid amount, the quality of acid solution to albumen of pH<4 has negative effect; Centrifugally obtain rice protein, after directly washing with water, due to the rising of pH value, in solution, the cadmium ion of stripping is combined with rice protein again, reduces the efficiency of finished product except cadmium; And also contain more acid solution in supernatant and water lotion, do not consider in this patent of invention that its discharge is to environment this point.
The patent of invention of CN103340414A discloses a kind of method for removing cadmium of rice protein, this invention comprise the steps: to size mixing mixing, acid hydrolytic reaction, removal of impurities, sterilizing, dehydration, drying obtains rice protein powder, this invention acid hydrolytic reaction adopts citric acid adjust ph 3.8 ~ 4.2, then with aqueous slkali, pH value is recalled to 5.8 ~ 6.2 again, the cadmium ion of stripping recombines with rice protein again along with the rising of pH value in acid condition, which decreases the efficiency except cadmium; Although used eddy flow washer in this invention, its main application plays separation, impurity removal, by the object that the supernatant and solid phase of having adjusted alkali are separated.
The patent of invention of CN104000085A discloses the preparation method of a kind of de-cadmium rice starch and de-cadmium rice protein powder, it mainly comprises immersion, defibrination, be separated, de-cadmium, sterilizing, the steps such as oven dry, in the step of this patent cadmium in removing rice starch and rice protein, mainly utilize the acetic acid of pH<4.2, lactic acid, oxalic acid, citric acid, tartaric acid, at least one in citric acid, be that 1:3-5 reacts according to rice raw material and sour volume ratio, adjust ph effect is mainly played with acid in this invention, negative impact is there is in this addition for the quality of rice protein and rice starch, use the clear water rinsing twice of the slant acidity of pH value 6.0-6.5 afterwards, the cadmium ion that this step take into account stripping when pH value raises can again with protein combination, but the cadmium that the pH value 6.0-6.5 adopted still can make part stripping again with protein combination and can not being separated out, which decrease the clearance of cadmium, in slurries, the acid that pH is 2.8-3.0 is added again after this rinse step, and, 2-3h under 80-85 DEG C of condition is adopted in ensuing sterilization steps, such treatment step is to rice protein, particularly the quality of rice starch can produce serious influence, therefore, this contrast patent of invention is not considering the impact of processing step on product quality completely while cadmium, and the cadmium ion removing stripping in cadmium technique does not adopt again effective means to be separated.
The patent of invention of CN103549234A discloses a kind of method of cutting down cereal heavy metal, this invention is with the rice of heavy metal pollution, the cereal such as wheat and maize and rice bran, the accessory substance of the cereal processing such as wheat bran is raw material, the heavy metal cadmium of compound national standard is obtained through some steps, plumbous, arsenic, the corn gluten protein of mercury and nickel content, the product such as cereal starch or polysaccharide, in this contrast patent of invention, material is mainly to the step of corn gluten protein removing heavy metals swelling, adjust ph 2-3, then through UF membrane, solution pH value 4-6 solution sedimentation separation in film, use running water agitator treating again, precipitation is dry, theoretically really can separate dissolved heavy metal ion out by the method for UF membrane, but for rice, the cereal such as wheat and maize and rice bran, in the accessory substance of the cereal processing such as wheat bran, composition is comparatively complicated, the efficiency of UF membrane is lower, and easily block, clear up complexity, be not easy to realize large-scale production and application, disclose with pickling starch or polysaccharide removing heavy-metal in this documents, used acid is the inorganic or organic acids such as hydrochloric acid, phosphoric acid, acetic acid, citric acid, tartaric acid, its main purpose is in order to the heavy metal in stripping starch or polysaccharide, but follow-uply directly add tap water, the heavy metal of stripping is formed again in conjunction with state, and the removal efficiency of heavy metal reduces.
