Cinnamic acid enzymatically synthesizes L-phenylalanine, an important food additive, the main raw material for sweet aspartame. Unilever of the United Kingdom has obtained the WIPO Patent PCTInt. Appl. Wo01 87, 080 (2001, 11.22) This article describes the composition of cinnamic acid and pasteurization aids and has a strong bactericidal and antiseptic effect.
Cinnamic acid is also a cinnamic acid hydrolase, a component of capsaicin synthase, and can be used to cultivate capsicum fine varieties with high yield of capsaicin content, which will greatly improve the quality of peppers, thus effectively promoting the development of pepper industrialization. The use of cinnamic acid for anti-mildew, anti-corrosion and sterilization can be used for preservation and preservation in food, vegetables and fruits. It can also be used in wine to make it bright and shiny. Cinnamic acid has a strong stimulatory effect and can be widely added directly to all foods.
The application of cinnamic acid in organic synthesis and chemical industry. In terms of organic chemical synthesis, cinnamic acid can be used as a sustained-release agent for galvanized sheet, a thermal stabilizer for polyvinyl chloride, a cross-linker for polyurethane, acetoyl and polyacetylene. Caprolactam flame retardants, chemical analysis reagents. It is also the reagent for determining the separation of uranium and vanadium; it is also the main raw material for the synthesis of negative photosensitive resin. The main synthesis of cinnamate, polyvinyl alcohol cinnamate, ethyl polyethylene oxide cinnamate and the side of the epoxy resin cinnamate.
Cinnamic acid is used in plastics. It can be used as a heat stabilizer for PVC, bactericidal anti-mold and deodorant. It can also be added in rubber and foam plastics to make deodorant shoes and insoles. It can also be used in cotton cloth and various synthetic fibers and leather. , paint, shoe polish, mats and other products to prevent mildew. The application of cinnamic acid propolis, honey bee products include honey, pollen, royal jelly, propolis, beeswax, bee venom and bee larvae, etc., is a full range of nutritional products and drugs. Due to the complex composition of bee products, it not only has the functions of regulating human physiology, improving immune function, enhancing physical strength, eliminating fatigue, anti-aging, inhibiting tumors and cosmetology, but also treating and assisting in the treatment of many kinds of chronic diseases, and is therefore attracting the attention of scholars around the world. A lot of work has been done on the chemical, pharmacological action and clinical application of bee products. The cinnamic acid steps were drawn and the standard curve was drawn. The standard solution (20 μL) was accurately drawn into the high performance liquid chromatograph. The absorbance value of the cinnamic acid was measured at a wavelength of 278 nm using an ultraviolet absorption detector. The concentration of the standard solution was used for the sample and the internal standard. The peak area ratio of the peak is plotted as a standard curve, and linear regression is performed to obtain a regression equation. Precisely draw 20 μL of the test solution into a high performance liquid chromatograph, measure the absorption of cinnamic acid at a wavelength of 278 nm using an ultraviolet absorption detector, and calculate the content.
