Potassium cinnamate, nature, use and production process Food preservative Potassium cinnamate is the potassium salt of natural cinnamic acid. It is also a new product newly developed in the field of food preservatives. It is non-toxic and harmless to the human body, safe and convenient, and has many health functions for the human body. And the application prospects, its advent has caused the vibration of the food antisepsis industry. After the preservative sodium benzoate was identified as susceptible to carcinogenicity by the UK Food Safety Authority, most countries have banned the use of potassium sorbate, which has become a common food preservative. However, traditional preservatives such as potassium sorbate only change the environment around the food to achieve anti-corrosion purposes, and cannot be integrated with food, and within a limited range of dosage, there is still residue in the human body, which is harmful to health. Potassium cinnamate can be completely combined with food, and will not become a foreign body of food. Without changing the original flavor and nutritional structure of the food, it can be used together with the surrounding environment to achieve anti-corrosion purposes. When PepsiCo and Coca-Cola originally chose potassium cinnamate, they were cautiously worried that potassium cinnamate would change the original taste of its products for hundreds of years and affect its market. However, after the actual trial and repeated follow-up studies, the two cola companies found that potassium cinnamate not only completely maintains the original taste of the beverage, but also has a preservative effect of more than three times, and can be converted into a human body after being ingested. The essential amino acids provide the necessary trace element potassium in the body to avoid the occurrence of hypokalemia. The researchers of the two Coke companies also found that potassium cinnamate has the effect of dilating vascular smooth muscle and strengthening blood circulation, which can improve the body's ability to resist fatigue, regulate body function and enhance immunity. The Coca-Cola Company has produced a health-care carbonated beverage with potassium cinnamate as its main additive, which is marketed in the Nordic markets such as Iceland and Finland. The Food and Agriculture Organization of the United Nations and the World Health Organization have strict restrictions on the recommended use of food additives and recommend that they be phased out, but there is no restriction on the amount of potassium cinnamate used and the daily intake of the human body. The advent of potassium cinnamate will reverse the perception of additives, completely eliminate the fear of food additives, become a milestone in the historical development of food additives, and will set off a food health revolution around the world! Antibacterial spectrum The use of potassium cinnamate enables the product to expand the antibacterial spectrum, synergistically improve the antibacterial effect, and have high safety. In particular, the yeast, mold, and bacteria causing food spoilage have the strongest effect, and the effective concentration for inhibiting mold is 0.05- 0.1%, the usual amount is 0.1-0.2%, and the effective concentration of inhibiting bacteria is 0.01-0.1%. The main inhibitory objects include pseudomycin, Micrococcus, Bacillus, Enterobacter, Vibrio, Halophilic, Aerophilic, Lactobacillus, Lactobacillus, Aflatoxin, Escherichia coli, Proteus vulgaris, Lactobacillus casei, Butyrobacter, Lactobacillus plantarum, Bacillus aerobacter, Gram-negative, positive bacillus, Botox, and the like. At the same time, potassium cinnamate is not limited by the pH, the bacteriostatic effect is also good between pH 2-7, and the bacteriostatic effect does not change due to fluctuations in pH, and can be widely used in various foods. Potassium cinnamate is a non-toxic, slightly cinnamon-scented, bactericidal preservative and antioxidant that dissolves easily into water. It will replace traditional preservatives; it has anti-fatigue, promotes metabolism, reduces inflammation, fights cancer, dilates blood vessels, and keeps excitement. And health care functions such as blood pressure reduction, also used as a blend of food spices. It can be directly added to foods, or it can be used as a main ingredient to make functional drinks and health foods. Meat product preservation Because potassium cinnamate has good solubility and antiseptic properties, and is safe and non-toxic, it is widely used in the processing of meat products such as cold meat, enema, ham, meat and canned meat. After many experiments, it has been proved that adding a certain amount of potassium cinnamate during the processing can have a good antiseptic and fresh-keeping effect. For example, after applying cold meat, it can effectively prevent mold and mildew, and can effectively keep fresh. The color and flavor of the meat, and has multiple functions such as water retention, anti-oxidation and stable fresh meat quality; it can effectively improve the color and flavor of the ham in the ham, and has multiple functions such as water retention, anti-oxidation and improvement of ham quality. And can reduce the amount of sodium nitrite used, effectively solve common problems such as acid decay and swollen bags in ham. spices Potassium cinnamate itself is a kind of spice, which has a good aroma retention effect, and is usually used as a raw material for fragrant, which makes the aroma of the main fragrance more volatile. Various esters of cinnamic acid (such as A, B, C, D, etc.) can be used as a deodorant for beverages, cold drinks, candy, alcohol and other foods. N-propyl cinnamate, also known as β-phenyl propyl acrylate, has a special peach apricot and wine-like aroma. It is widely used in the flavoring agents of food, tobacco, cosmetics and soap. It is a spice to be developed. At the same time, potassium cinnamate can also be used as apple flavor, cherry flavor, fruit flavor, floral fragrance and can be used as an aromatic mixture in soap, shampoo, washing powder and daily cosmetics. In the application of cosmetics, it has the effect of inhibiting the formation of black tyrosinase, has a certain insulating effect on ultraviolet rays, can make brown spots lighter or even disappear, and is one of the essential components in advanced sunscreens. safety The oral LD50 of potassium cinnamate was 5.58-6.78g/kg, which was a non-toxic product, while the oral LD50 of sodium benzoate was 2.7-4.44g/kg. Potassium cinnamate is absorbed into phenylalanine after being absorbed by the body (phenylalanine is a kind of α-amino acid, one of the essential amino acids of the human body) is excreted by metabolism, and a small amount of phenylalanine can be phenylalanine hydroxy The enzyme catalyzes the production of tyrosine (tyrosine is one of the 20 amino acids that make up the protein and is an essential amino acid in mammals) and has no toxic or accessory effects on the human body. Its effective preservative ingredient, cinnamic acid, was identified by the FEMA (Flavor Extract Manufacturers Association) in 1965 as GRAS (which is generally considered safe).

Soluble in hot water, alcohol, benzene, chloroform, ether, glacial acetic acid, petroleum ether and carbon disulfide, slightly soluble in cold water. It can volatilize with water vapor. Parkinson's disease, also known as "tremor palsy", is a central nervous system degenerative disease, most commonly found in middle-aged and elderly people, and is listed by the World Health Organization as one of the "world's difficult diseases." With the aging of the society, there are more than 1.8 million Parkinson's patients in China, and the incidence is increasing at a rate of 0.1% per year. Because there is no suitable medical treatment, about 20-25% of patients eventually lose their lives. ability. In order to solve this problem, in 2005, Denmark LUNDBECK company and Israel TEVA company developed a rasagiline through long-term joint experiments. Compared with the first generation of therapeutic drugs, according to the Canadian Medical Post report, rasagiline treatment can relieve the symptoms of Parkinson's disease for up to 6 years, and also has a certain protective effect on the nerves. However, due to the high price of raw materials and the complicated preparation methods, the price of rasagiline has remained high and the patients are suffering. The latest research found that rasagiline is prepared by using low-cost hydrogen cinnamic acid as an intermediate. It has the advantages of simple operation, low cost and high yield. The price of regagiran is cheaper than other drugs. More than 50% brings new hope to patients. In addition, the recent International Institute of Chemistry has shown that hydrogenated cinnamic acid can also be used as an intermediate in the treatment of the diabetes drug glibenclamide. Diabetes is a worldwide stubborn disease, and its alias for foreign countries is called "silent killer." There are currently more than 92 million diabetic patients in China, and another 100 million are potential patients. Glibenclamide is the most effective drug for oral hypoglycemic, but it has been expensive due to the price of raw materials and has strong toxic side effects. In the modern pharmaceutical industry, the cinnamon series-hydrocinnamic acid is used as an intermediate, which has certain auxiliary effects on reducing side effects and lowering blood sugar.

Simultaneous determination of the anticonvulsants, cinromide (3-bromo-n- ethylcinnamamide), 3-bromocinnamamide, and carbamazepine in plasma by high- performance liquid chromatography. 3-Bromocinnamic acid is used as an organic synthesis of raw materials, fine chemicals, pharmaceutical intermediates. Abstract A high-performance liquid chromatographic method is described for monitoring plasma concentrations of cinromide (3-bromo-N-ethylcinnamamide) and its de- ethylated metabolite. Carbamazepine levels can be easily measured by the same technique. The N-isopropyl analogue of cinromide is used as internal standard, and all compounds are easily separated on a reversed-phase column operated at 55 degrees with a small-diameter pre-column maintained at the same temperature. The extraction is rapid and generally applicable to plasma and urine samples that are to be analyzed by reversed-phase chromatography. Short- and long-term reproducibility studies show less than 4% relative standard deviation for replicate determinations for all drugs. Limits of quantitation are 10-20 ng/ml with an internal standard concentration of 3 micrograms/ml. Another metabolite of cinromide, 3-bromocinnamic acid, which may have some anticonvulsant effect, can be analyzed simultaneously by buffering the mobile phase and adding an ion-pairing reagent. Storage: Pay attention to the source of fire, especially to avoid sunlight, and store in a cool place.

Slowly decompose in water. Storage Keep container closed when not in use. Store in a cool, dry, well-ventilated area away from incompatible substances. Corrosives area. Refrigerator (approx 4 C). Store protected from moisture. Handling Keep container tightly closed. Do not get on skin or in eyes. Do not ingest or inhale. Use with adequate ventilation. Discard contaminated shoes. Application: Used as an intermediate in organic synthesis for the determination of trace moisture. This product can be used as an intermediate in organic synthesis. Cinnamamide can be prepared by amidation, and n-cinnamyl -nphenylhydroxylamine can be prepared by interaction with phenylhydroxylamine. Cinnamyl chloride can also be used to synthesize the anti-inflammatory and analgesic drug Sinnoxicam (cinnoxicam) and other fine chemicals. A reagent for the determination of trace water. Production preparation: Cinnamyl chloride is obtained by the reaction of sodium cinnamate with acetyl chloride. The acetyl chloride and benzene are mixed into solution, and the dried sodium cinnamate is added several times under stirring from time to time. After each addition, the carbon dioxide is released and the next time is added. Then reflux for 2 hours. After a little cooling, the resulting sodium chloride and trace unreacted sodium cinnamate are filtered out. The filtrate was distilled to remove benzene at atmospheric pressure and then distilled at 131C (1.47kPa) to obtain the product in 75-90 yield. Carbon tetrachloride can be recrystallized when purification is needed. Cinnamyl chloride was prepared by the reaction of cinnamic acid with dichloro sulfoxide. Polyvinyl cinnamate adhesive (PVAC,) is a linear polymer compound with molecular weight of 15000 ~ 20 000, which is obtained by esterification of polyvinyl alcohol and cinnamyl chloride. The photosensitive adhesive was prepared by adding 5- nitroacenaphthene and organic solvent cyclohexanone, that is, the double bond of the molecule was opened and solidified under ultraviolet light irradiation. It has important applications in the manufacture of integrated circuits and micro components. A photoresist, polyvinyl cinnamate, synthesized from polyvinyl alcohol and cinnamyl chloride in a pyridine solvent. The prepared photoresist is called KPR.. The photochemical dimerization of the double bond of cinnamate was formed under the action of ultraviolet light, and it was turned into an insoluble substance. KPR was the first photoresist used in photolithography, and 5- nitroacenaphthene was usually added as Guang Min. Photoresist, also known as photoresist, can be used in photolithography, which is widely used in printing and electronic industry. Its working principle is that the light part is crosslinked to form the insoluble hardening film, which is processed into negative image (negative glue), or the original insoluble glue becomes soluble after illumination, and is processed as a positive image (positive glue).
