Methionine has wide application fields and my country’s import substitution process continues to accelerate.

Methionine, also known as methionine and methylthiobutyric acid, has a molecular formula of C5H11O2NS and is an organic compound. Methionine appears as a white crystalline powder with a special odor. It is soluble in dilute alkali, dilute acid and water, but insoluble in ether. Methionine has optical activity and detoxification effects, and can be used to produce medicines, nutritional supplements, feed additives, condiments and other products. According to different structures, methionine can be divided into three types: D,L-methionine, L-methionine and D,L-hydroxymethionine.

The methionine industry has high technical barriers and the production process is relatively complex. Chemical synthesis, protein hydrolysis, microbial methods, etc. are the main preparation methods of methionine. According to different raw materials, chemical synthesis methods can be divided into acrolein method, malonate method, aminolactone method, etc. The acrolein method uses methylmercaptan, acrolein and hydrocyanic acid as the main raw materials, and produces methionine through Strecker synthesis reaction. The acrolein method has the advantages of low production cost and good quality of finished products, and is widely used in the industrial production of methionine.

my country is the world’s largest consumer of methionine. For a long time, my country has mainly relied on imports of methionine. As the independent research and development capabilities of local enterprises continue to improve, my country’s methionine production capacity has rapidly expanded, output has continued to grow, and the import substitution process in the market has further accelerated. According to statistics from the General Administration of Customs of China, from January to November 2022, my country’s solid methionine imports reached 164,000 tons, a year-on-year decrease of 10.1%; exports reached 109,000 tons, a year-on-year increase of 43%. At present, Japan, Indonesia and Germany are my country’s main exporters of methionine.

According to the “2023-2028 China Methionine Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center , Methionine has a wide range of applications, including medicine, nutritional supplements, feed additives, condiments, etc. In the field of medicine, methionine can be used to prepare antidepressant drugs, liver-protecting drugs, etc.; in the field of nutritional supplements, methionine can assist sleep and promote cell metabolism; in the field of feed additives, methionine can Acid can inhibit toxins and promote animal growth.

There are many methionine production companies in my country, and the market competition is fierce. Adisseo, Xinhecheng, Leer Chemical, Hebang Biotech, Jincheng Pharmaceutical, Huayuan Biotech, etc. are the main methionine manufacturers in my country. Xinhe has become my country’s leading methionine enterprise. The company’s current production capacity has reached 150,000 tons, ranking among the top in my country.

Industry analysts said that methionine has a wide range of applications and the industry has good development prospects. Benefiting from the accelerating development of downstream industries, my country’s methionine market space continues to expand. In recent years, driven by the technological innovation of local enterprises, my country’s methionine production capacity has expanded rapidly. However, at present, my country’s methionine is still mainly imported. In the future, as the technological maturity continues to improve, the import substitution process in our country’s market will further accelerate.
