Capsaicin application in the pesticide

Capsaicin is extracted from natural plant pepper, the pure product is white crystals, melting point is 65 , almost insoluble in cold water, soluble in ethanol, acetone and other solvents. 

Due to the capsaicin derived from natural,Guest Posting and the special pharmacological activity, long time development and application, new uses of biological pesticides continue to be developed, so that its prospects for development of the market is quite broad.

In the field of bio-pesticides, the product as a new type of green pesticides has good contact toxicity, repellent, pest control on crops can achieve high efficacy holders effective and biodegradable characteristics, is a new type of environmentally friendly biological in 21st century. Long time ago it has confirmed that capsaicin and its products is a biochemical pesticide, and exempt from the restrictions applied to residues on fruits, vegetables and grains, making it sharp increase in pesticide market dosage. Through a long-term test, optimize the product screening mixed, has developed emulsion-type products, and sentinel field efficacy verification by the Ministry of Agriculture to promote the use.

For a long time, the international community also can not be achieved synthetic physiological activity of capsaicin, Capsaicin supplier only through physical extraction method from the product obtained in the chili. The traditional method is the use of the extraction of the organic solvent as the extraction agent, the process requires after up to 11 times the sub-phase process, plus the residual solvent, it has been severely limited in the range of applications in the pesticides. In recent years, with the development of supercritical CO2 extraction technology has been successfully realize the application of the technology in the preparation of capsaicin products, not only simplifies the production process, and the product obtained has made great strides in color and taste improve and also to avoid the pepper of green grass, to improve the grade of the product and the range of market applications. At the same time, waste utilization extract capsaicin has also been a breakthrough, so that the entire production process waste emissions, environmental pollution, is the true sense of the green production process.

The product on the market demand, with the continuous promotion and application in the field of pesticides, pharmaceuticals, food additives, its market demand increases year after year, the current conservative market demand has more than 4000 tons / year in the world, while the total production of the worldcapacity was less than 2,000 tons / year, up to 50% of the demand gap. Great, especially in recent years, sales of the product once the products are extremely scarce resulting in product price up to $ 40,000 / kg, the current international market price remained at 3.0 ~ $ 40,000 / kg, and subject to availability fluctuations than large. About 60% of capsaicin used as pharmaceutical raw materials, about 15% used in pesticides.

Capsaicin production applications is still in its infancy, the production capacity of 200t / a, export-oriented products. The large number of applications have not yet been realized in the field of pharmaceuticals, pesticides and other limited to a small amount of low concentrations of products used in the field of high-end food additives, most of the remaining products are exported to Japan, South Korea, the United States and other countries. Of the product in the field of pesticide breakthrough emulsion type of pesticide products to market. With the strengthening of environmental awareness in the people's health, the natural green vegetables have become the first choice for people in dining table, increasing requirements for pesticide residue standards, therefore efficient environmentally friendly green pepper alkali pesticides residue, provides a broad market space for development.
