The application prospects of polyglutamic acid are promising and the current market supply exceeds demand.

Polyglutamic acid (γ-PGA), also known as γ-polyglutamic acid, natto gum, polyglutamic acid, etc., is a compound formed by combining L-glutamic acid and D-glutamic acid through γ-amide bonds. A high molecular weight amino acid polymer. Polyglutamic acid contains a large number of amide bonds and free carboxyl groups. Its unique molecular structure gives it good biocompatibility, biodegradability, safety, stability and water absorption. With its good performance, polyglutamic acid is used in Biodegradable plastics, medicine, environmental management, sewage treatment, fertilizers, cosmetics and other fields are widely used.

According to the “2021-2025 Polyglutamic Acid Industry In-depth Market Research and Investment Strategy Suggestions Report released by the Industrial Research Center, As a bio-based material, polyglutamic acid has promising application prospects, and the industry’s profit margins remain high. Attracted by the good market prospects, the number of companies entering this market continues to increase. At this stage, there are more than 20 domestic polyglutamic acid manufacturers, with a production capacity of 100,000 tons/year. However, due to production process limitations, the actual output of polyglutamic acid is low, at about 20,000 tons.

From the perspective of production technology, polyglutamic acid has a variety of production processes, including chemical synthesis, natto extraction, biological fermentation, etc. Among them, chemical synthesis is divided into peptide synthesis and dimer condensation. Production by chemical synthesis is extremely difficult and costly, and has no industrial application value. Therefore, the current production process of polyglutamic acid is to ferment natto to produce natto bacteria and then ferment it. Domestic institutions engaged in research on polyglutamic acid biological fermentation technology include Zhejiang University, Nanjing University of Technology, etc.

In the international market, developed countries such as the United States and Japan started research on polyglutamic acid earlier, and their research levels are in a leading position in the world. Japan is an important producer and exporter of polyglutamic acid in the world. Related production companies include Ajinomoto, Meiji Confectionery Co., Ltd., etc. In the domestic market, large-scale polyglutamic acid manufacturers include Shandong Freda, Ainongstar Crops, Wuhan Guanghua Times, Wanheng Biology, Nanjing Xuankai, etc.

According to different application fields, polyglutamic acid can be divided into fertilizer grade, cosmetic grade, agricultural grade, food grade and pharmaceutical grade. At present, the downstream market of polyglutamic acid is mainly concentrated in the fields of cosmetics and chemical fertilizers, but in other fields Polyglutamic acid also shows good application prospects in fields such as medicine, agriculture, food, and fertilizers. With the continuous optimization of production processes, the polyglutamic acid market has huge development potential in the future.

Industry analysts said that it is difficult to produce polyglutamic acid. Due to the limitations of the production process, the actual output of polyglutamic acid in my country is relatively small. Low, insufficient to meet the growing market demand, so the current polyglutamic acid market is still in short supply. As a bio-based material, polyglutamic acid is degradable, safe and environmentally friendly. Under the background of increasingly stringent environmental protection supervision, the application fields of polyglutamic acid will be further expanded, and the future market development prospects are promising.
