What are the new food additives?

1) hydroxypropyl methylcellulose is a cellulose derivative successfully developed by Dow Chemical Company in the United States. As a food additive, it has been proved to be a cholesterol-lowering agent, which has potential advantages compared with the existing cholesterol-lowering agents. It is reported that the additive introduced by Dow Chemical Company is high molecular weight hydroxypropyl methylcellulose (HPMC), which comes from natural cellulose and is not expensive. Practice has proved that in many cases, this compound can lower the cholesterol level more than popular drugs, and has no toxic and side effects, so this development work of Dow Chemical Company shows great practical significance. At present, some HPMC products have been marketed as additives for cheesecakes, puddings and other foods, and can also be used in pharmaceutical applications, such as tablet coating, controlled release agents and granulation adhesives. Researchers believe that the future prescription drugs of HPMC can be made into liquid or mixed into medicated diets, desserts and drinks, so that people can lower their cholesterol levels while eating desserts. The University of Michigan and Dow Chemical Company have begun to provide funds for the clinical research of hydroxypropyl methylcellulose and apply for patents for the cholesterol-lowering use of HPMC. 2) polyglycerol -3 monoester polyglycerol -3 (polyglycerol -3) monoester is a water-soluble product produced by Solvay Interox Company. The production process of Solvay polyglyc-Errol-Errol-3 can ensure the narrow distribution of oligomers and only contain a small amount of glycerol, thus reducing the formation of cyclic compounds and narrowing the differences between batches. Because of this characteristic, monoester forms a stable colloidal phase, which makes the residence time of emulsion and foam longer than that of glycerol. Compared with similar esters produced by traditional polyethylene glycol, monoester has better emulsifying property. Esters made from Solvay polyglycerol -3 have unique properties and can be used in food and cosmetics. When used in cosmetics, it may form a hydrophobic film on the skin, making the skin feel soft and moderately moist, and the ingredients are easy to wash without leaving any residue. These esters have great viscosity in surfactants and can dissolve or disperse bioactive substances (such as protein). Unlike the corresponding glycerol, these esters can meet the general stability requirements of pharmaceutical preparations. The selected esters can be used as food additives in baked goods, shortening, salad dressing and other condiments. Unlike the corresponding glycerides, dehydrated paste emulsion made of sodium polyglycerol -3 monoester can be stored for several weeks. Moreover, it is very important in the industrial production of baked goods, so that it can be produced in large quantities, and the food is fresher and has a long shelf life. 3) Selenium polysaccharide Selenium polysaccharide, also known as K-carrageenan selenide, is a polysaccharide compound containing selenium. As a new type of organic selenide, it can be widely used in biomedicine, health food, medical beauty cosmetics, food, feed additives, ecological agriculture and other fields. Due to the continuous development of its uses, it has great market potential and development prospects. Selenium polysaccharide, as an ideal selenium supplement product, gives full play to the physiological activities of selenium and polysaccharide and enhances their functional coordination. Compared with similar products, selenate polysaccharide has four characteristics: first, it combines the ability of selenium to scavenge free radicals with the quenching effect of carrageenan itself, which effectively improves the bioavailability; Second, selenite polysaccharide with organic structure has the lowest toxic and side effects compared with other inorganic selenium; Thirdly, it has good water solubility and compatibility, and can be used to develop various functional foods, such as replenishing essence and marrow, strengthening brain and improving intelligence, resisting aging, resisting fatigue, relaxing bowels, expelling toxin and caring skin, reducing fat and losing weight, clearing liver and improving eyesight, nourishing liver and protecting kidney, etc. Does not affect the original flavor of food; Fourth, the antioxidant performance is remarkable, and it can be used as a good antioxidant and stabilizer for food production, effectively ensuring food quality. During the period of 1992, selenate polysaccharide, which was first developed and produced by Shanghai Tianfu Group in China, officially passed the joint final review of the Ministry of Health, the Ministry of Chemical Industry, the Ministry of Light Industry and the State Quality Supervision Bureau, and was officially approved as a nutritional additive for health food, and issued a production license and a hygiene license. In the same year, it was declared as a national first-class new drug to the Ministry of Health. At present, the second phase of clinical practice has been completed and is awaiting approval. 4) Spartina polysaccharide Chinese scientists successfully extracted Spartina polysaccharide by using new drying technology, and turned Spartina polysaccharide, which is known as "harmful grass", into "precious grass". Shanghai Shouqi Polysaccharide Food Research Institute found that Spartina is rich in protein, vitamins and trace elements, which is the best raw material source for extracting active polysaccharides. They adopted the world-class new technology of double enzyme hydrolysis and ultra-low temperature freeze sublimation drying, and the "rice grass polysaccharide" extracted from rice grass far exceeded the polysaccharide content of general extracts. It is identified as an ideal raw material for medicine and health food, and can be used to develop extremely cheap polysaccharide drugs, polysaccharide health food, polysaccharide drinks, food additives, pollution-free pesticides, polysaccharide feed and so on. Spartina is a Gramineae plant that grows on river banks and beaches, and has been introduced in large scale all over the world. The original intention of planting rice grass in China is to resist wind and waves, protect beaches and revetments, and promote siltation and reclamation. Unexpectedly, because of its strong resilience and fecundity, its growth rate is beyond people's control, which leads to ecological imbalance in tidal flats, siltation of navigation channels, obstruction of tidal flat culture, suffocation of marine life, red tides and so on. Therefore, it is called "harmful to grass". Scientists from all over the world gathered in new york, USA, to study the countermeasures, and put forward some methods to stop its harm, such as burning, knife cutting, insect bite, drug killing, etc., but with little effect. According to scientific determination conducted by researchers, the cost of Spartina polysaccharide per ton of raw materials is only 1400 yuan. Only in Ningde, Fujian, there are 500,000 tons of Spartina, which can produce 65.438+0.5 million tons of Spartina polysaccharide, with an annual output value of 65.438+0.5 billion yuan and an annual profit of 7.95 billion yuan. At present, China is the country with the largest planting area of Spartina in the world, distributed in more than 80 counties and cities across the country, and also proliferated in the Yellow River Delta, Bohai Bay and Jiangsu coastal areas. If the extraction technology of Spartina polysaccharide is popularized in the whole country, the economic benefits will be considerable. See www.rmhot.com5 for relevant information) The first 200t/a ethyl vanillin production plant with glyoxylic acid as the main raw material in China was completed and put into operation in the research and experimental plant of Jihua Group Company in July 2003. Ethylvanillin is one of the most important synthetic spices in the world today, and it is an indispensable raw material for food additive industry. Its aroma is 3-4 times that of vanillin, with strong vanilla bean aroma and lasting fragrance. Widely used in food, chocolate, ice cream, drinks and daily cosmetics, it plays a role in enhancing fragrance and fixing fragrance. In addition, ethyl vanillin can also be used as feed additive, brightener in electroplating industry and intermediate in pharmaceutical industry. The process of producing ethyl vanillin with glyoxylic acid as the main raw material is an advanced production technology in the world. The project was jointly developed by Jihua Group and Jilin University. This technology has solved the problems of serious environmental pollution, long process flow and low product yield in the existing vanillin production facilities in China, and the products have reached the FCC Ⅳ Ⅳ standard in the United States and the Japanese additive standard. The aroma of this product has been identified by Shanghai Institute of Spice, which completely meets the aroma standard. The completion of the device fills the gap in the technology of producing ethyl vanillin from glyoxylic acid in China.
