Environment-friendly additive capable of improving rice nutrition value and food safety and preparation method thereof

Abstract

The invention relates to an environment-friendly additive capable of improving rice nutrition value and food safety and a preparation method thereof. The additive comprises food rich in dietary fiber, cinnamic acid, phosphoric acid or phosphate, an acidity regulator and chloride. The additive is directly added into washed rice, and cooked rice has the antibacterial and anti-corrosion functions and is long in shelf life. Before the rice enters the mouth, the stomach and the intestines of a human body, the leaching and dissolving amount of heavy metal contained in the rice can be reduced, even if acidity is higher than gastric acid of the human body or even in an extremely abnormal environment like a 1N hydrochloric acid solution of acid rain, the heavy metal can form products which are not easy to decompose and whose chemical properties are not active, the products can not be absorbed by the human body easily, migration, diffusion and conversion of the products in the environment are reduced, and therefore the heavy metal is prevented from returning to the food chain, the nutritional value of rice is improved, dietary fiber is added, calcium is supplemented, and application prospects are good.

Description

technical field [0001] The invention belongs to the technical field of food additives, in particular to an additive for stabilizing heavy metals, improving the nutritional value of rice, food safety and environmental protection and a preparation method thereof. Background technique [0002] Rice is divided into three categories: indica rice, japonica rice and glutinous rice according to variety type, grain row, and grain quality. Indica rice and japonica rice are particularly important, and the trade volume of indica rice is the largest. Southeast Asia, Africa and Latin America mainly consume indica rice, especially long-grain rice. People in Japan, North Korea, Italy and other countries like to eat japonica rice. Orientals, including people in southern my country, generally eat rice as their staple food. Rice can provide rich vitamins, oryzanol, protein, anthocyanins and other nutrients. But indica rice and japonica rice contain only a small amount of calcium and dietary...

Problems solved by technology

[0012] The above-mentioned natural foods and antioxidants, Chinese invention patent bracken flavonoid extract, invention patent stachyose-containing lead-expelling health products, and low-molecular-weight citrus pectin only show that they adsorb, chelate or complex free heavy metals, and further Intestinal peristalsis, promoting excretion, can excrete heavy metals as soon as possible, but there is no scientific basis or reaction mechanism to prove that they can leach heavy metals that are harmful to food safety, mainly including lead, cadmium, arsenic, copper, and mercury. The effect of reducing the effect and forming a harmless, chemically inactive form of heavy metal stabilizers, that is, after being discharged into the environment, most of them may still be reduced to harmful soluble and free heavy metals, through the migration in the environment, Diffusion, transformation and back to the food chain, and finally back to the dining table
