Embodiment 1

[0029] A processing method for reducing arsenic content in rice, specifically comprising the following steps:

[0030] Step 1, hulling treatment: select the rice that needs to be processed, put the rice into the huller, use the huller to hull the rice, and collect the separated brown rice through the collection bag, repeat the operation twice, and the brown rice Cool to room temperature;

[0031] Step 2. Brown rice processing: Pour the brown rice obtained from shelling treatment in Step 1 into the filter device to filter, remove the stone particles in the brown rice, and then further screen the filtered brown rice through a magnetic screen to remove the metal in the brown rice Small particles, after several operations, pour the brown rice into the prepared measuring bucket for later use;

[0032] Step 3. Preliminary arsenic removal: add water to the spare brown rice in the measuring bucket in step 2 to submerge the brown rice, stir with a stirring device, and then use an ultr...

Abstract

The invention discloses a processing method for reducing arsenic content in rice. The processing method comprises the following steps of step I, performing shelling treatment: selecting unhulled riceneeding processing treatment, putting the selected unhulled rice in a rice huller, shelling the unhulled rice through the rice huller, performing separation to obtain brown rice, performing collectionthrough a collecting bag, and performing repetitive operations twice. The invention relates to the technical field of modern agriculture industry. According to the processing method for reducing arsenic content in rice, the brown rice is stirred through a stirring device, and then the brown rice is subjected to ultrasonic treatment through an ultrasonic device, so that arsenious organic compoundson the surfaces of the brown rice can be preliminarily removed; then a sodium hydroxide solution reacts with the arsenic in the brown rice, arseniate is formed, further nitric reacts with the arsenicin the brown rice, arseniate is formed, then the arsenic in the brown rice is thoroughly removed, and the problem of higher arsenic content in the rice is effectively solved; and nutrition and mouthfeel of the processed rice are not influenced, the safety is guaranteed, and advantages are provided for sale of products.

Description

technical field [0001] The invention relates to the technical field of modern agricultural industry, in particular to a processing method for reducing the arsenic content in rice. Background technique [0002] Rice is the finished product of rice after cleaning, husking, rice milling, finishing and other processes. The germ and aleurone layers of rice contain nearly 64% of rice nutrition and more than 90% of the nutrients needed by the human body, and are the main food for people in most parts of China. Rice contains about 75% carbohydrates, 7%-8% protein, 1.3%-1.8% fat, and is rich in B vitamins. The carbohydrates in rice are mainly starch, and the protein contained is mainly rice glutenin, followed by rice gelatin and globulin. High, digestibility 66.8%-83.1%, is also a kind of higher in cereal protein. The content of lysine and threonine in rice protein is less, so it is not a complete protein, and its nutritional value is not as good as that of animal protein. But ea...
