[Synthetic Biology Advantage Product Recommendation] Market size 1.15 billion yuan, high-yield L-tryptophan production technology


Tryptophan, also known as β-indolylalanine, is an organic compound with the chemical formula C11H12N2O2 and is one of the essential amino acids for the human body.

Tryptophan is an important precursor substance for auxin biosynthesis in plants. Its structure is similar to IAA. It is ubiquitous in higher plants. also the precursor of 5-hydroxytryptamine, an important neurotransmitter in the human body. It can be used during pregnancy. Nutritional supplement for women and special milk powder for infants and young children. It is used for niacin deficiency (pellagra). As a tranquilizer, it can regulate mental rhythm and improve sleep. It is also one of the raw materials of compound amino acid infusion.

L-tryptophan application fields

L-tryptophan is the second feed-added amino acid after methionine and lysine. By adding L-tryptophan, the balance of amino acids can adjusted and the growth of livestock and poultry can be promoted.

Tryptophan an important amino acid that widely used in the fields of medicine, food and feed additives. It is one of the 8 essential amino acids for humans and animals. The human body cannot produce it and must ingest it from the diet. When the human body lacks tryptophan , not only causes general hypoegg syndrome, but also special diseases such as skin diseases, cataracts, vitreous degeneration and myocardial fibrosis.

In the food industry, it is mainly used as a food nutritional supplement. The most important nutritional function of L-tryptophan is to participate in protein deposition.

L-tryptophan is a non-protein active amino acid with special physiological properties. It also has certain value in the food and feed industry and agriculture. It can used as a non-nutritional sweetener, feed additive and plant growth agent. Domestic tryptophan production is still relatively low. It is in the initial stage of research and development, with less output and its use mostly limited to feed. There is less development in other application fields, and its application still mainly relies on imports.

Japan’s Showa Denko, Kyowa Hakko and Mitsubishi Petroleum & Chemical Corporation use fermentation methods to produce tryptophan, while Mitsui Totama, Tanabe Pharmaceuticals and Nippon Chemical Co. use synthetic methods to produce tryptophan. The German company Shaanxi 8usm uses fermentation and synthesis methods to produce tryptophan. A small amount of tryptophan produced by a pharmaceutical factory in Wuhan, my country, using a synthetic method.

Market size

1. Market size

Tryptophan increasingly used in medicine, food, feed additives and environmental monitoring. With the increase in market demand, my country’s tryptophan market size will be 1.156 billion yuan in 2021, a year-on-year increase of 7.50%.

2. Output

my country’s tryptophan production capacity and output are increasing day by day, becoming a veritable major supplier. The gradual increase in global feed production has driven the growth in demand for tryptophan. In addition, the export tax rebate rate for tryptophan has increased, and domestic companies are enthusiastic about exporting. order to seize market share, companies have strong momentum to expand production, and market supply continues to increase. In 2021, my country’s tryptophan production will be 20,600 tons, a year-on-year increase of 11.51%.
