Example Embodiment

[0091] Example 1

[0092] About 500g of indica rice containing arsenic (As) leaching toxicity concentration was selected as the sample for this implementation, and all were first washed with pure water.

[0093] (1) Sampling 175g of arsenic (As)-contaminated indica rice that has been washed above and adding an appropriate amount of pure water according to the usual method (such as the ratio of rice to water 1:1), and then putting it in an electric cooker to cook rice. After the uncooked rice is cooked into rice, let it cool for more than ten (10+) minutes, then take at least 250g of the rice in the pot, place it in a clear glass bottle, cover it, and send it for inspection and analysis. The HJ / T299-2007 solid waste leaching toxicity leaching test was performed on the samples using the GB5085.3-2007 hazardous waste identification standard leaching toxicity identification standard, but the extractant used 1NHCl (to simulate gastric acid but the acid strength is better than gastric ac...

[0098] Example 2

[0099] About 500g of indica rice containing cadmium (Cd) leaching toxicity concentration was selected as the sample for this implementation, and all were first washed with pure water.

[0100] (1) Sampling 175g of cadmium (Cd)-contaminated indica rice that has been washed above, adding 175g of pure water (rice to water ratio 1:1), and then putting it in an electric pot for cooking. After the uncooked rice is cooked into rice, let it cool for more than ten (10+) minutes, then take at least 250g of the rice in the pot, place it in a clear glass bottle, seal it, and send it for inspection and analysis. The HJ / T299-2007 solid waste leaching toxicity leaching test was performed on the samples using the GB5085.3-2007 hazardous waste identification standard leaching toxicity identification standard, but the extractant used 1NHCl (to simulate gastric acid but the acid strength is better than gastric acid) and the rice sample Shake in an extraction bottle for 24 hours (l...

[0105] Example 3

[0106] Approximately 500 g of lead (Pb) leaching toxic concentration of japonica rice was selected as the sample for this implementation, and all were first washed with pure water.

[0107] (1) Sampling 175 g of lead (Pb)-contaminated japonica rice that has been washed and added 175 g (rice to water ratio of 1:1) of pure water, and then put it in an electric cooker to cook rice. After the uncooked rice is cooked into rice, after it has cooled for more than ten minutes, immediately take at least 250g of the rice in the pot, place it in a clear glass bottle and seal it, and then send it for inspection and analysis. The HJ / T299-2007 solid waste leaching toxicity leaching test was performed on the samples using the GB5085.3-2007 hazardous waste identification standard leaching toxicity identification standard, but the extractant used 1NHCl (to simulate gastric acid but the acid strength is better than gastric acid) and the rice sample Shake in an extraction bottle f...

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...
