Application of deacetylated chitin (chitosan) in Rice

Introduction to the use of deacetylated chitin (chitosan) in Rice Introduction gold chitosan manufacturers learned that according to the provisions of the national standard of the people's Republic of China gb2760-2011 for the use of food additives, deacetylated chitin (chitosan) can be used as thickening agent and coating agent in rice, and the maximum use amount is 0.1g/kg. According to Wang Zhutian, deputy director of the Institute for nutrition and food safety of the Chinese Center for Disease Control and prevention, deacetylated chitin (also known as "chitosan") can be used as a coating agent for rice. The main function of this food additive used in rice is to keep rice fresh and prevent mildew. According to media reports, chitosan itself is a thickener and coating agent, and rice processing costs are high and profits are low, so it is rarely used in actual production. It is possible for grain enterprises to film or polish rice surface, to coat rice surface with a layer of film, just like fruit wrapped with preservative film, but the cost of this material is high. Deacetylated chitin (chitosan) is a kind of biological polysaccharide extracted from crab shell, which has the functions of bacteriostasis, insurance and health care. It can be directly added into rice or dissolved into 1% deacetylated chitin (chitosan) solution with 1% acetic acid solution, and then diluted with water according to needs, and then used in rice coating or polishing process.
