Through this period of understanding, I believe you are no stranger to food grade fumaric acid, but these contents are not enough for customers who want to further understand the relevant knowledge of this product. Today, Xiaobian will share with you the knowledge about the role of food grade fumaric acid, hoping to attract your attention and let you have a deep understanding of food grade fumaric acid. In this way, when purchasing and using food grade fumaric acid, we can also know well and take it easy. We hope to inspire and help you. Please see the following details:

在食品中主要用于肉制品、鱼肉制品加工等。食品级富马酸可作为酸度调节剂、酸化剂、助剂、腌制促进剂、香料使用。本品有强缓冲作用，以保持水溶液在pH3.0左右，并对防霉有重要作用，同时，它有涩味，是酸味的固体酸之一，吸收率低，有助于延长粉末制品等的保存期。当富马酸变为富马酸钠后，水溶性及风味均更好

It is mainly used in the processing of meat products and fish products in food. Food grade fumaric acid can be used as acidity regulator, acidifier, assistant, curing accelerator and spice. This product has strong buffering effect to keep the aqueous solution at pH 3.0, and plays an important role in mildew prevention. At the same time, it has astringent taste. It is one of the sour solid acids with low absorption rate, which is helpful to prolong the storage life of powder products. When fumaric acid is changed into sodium fumarate, the water solubility and flavor are better

食品级富马酸用于不饱和聚酯树脂，这类树脂的特点是耐化学腐蚀性能好，耐热性也好；反丁烯二酸与乙酸乙烯的共聚物是良好的粘合剂，与苯乙烯的共聚物是制造玻璃钢的原料，反丁烯二酸所制得的增塑剂，可用于与食品接触的乙酸乙烯乳胶。该品是医药和光学漂白剂等精细化学品中间体。

Food grade fumaric acid is used to produce unsaturated polyester resin, which is characterized by good chemical corrosion resistance and heat resistance; The copolymer of fumaric acid and vinyl acetate is a good adhesive. The copolymer with styrene is the raw material for manufacturing FRP. The plasticizer prepared by fumaric acid can be used for vinyl acetate latex in contact with food. The product is an intermediate of fine chemicals such as medicine and optical bleach.

在医药工业中用于药二巯基丁二酸的，将反丁烯二酸用碳酸钠中和，即得到反丁烯钠（[17013-01-3]），进而用硫酸亚铁置换得到反丁烯二酸铁，是用于小红血球型贫血的富血铁。该品作为一种食品添加剂——酸味剂，用于清凉饮料、水果糖、果冻、冰淇淋等，大多与酸味剂柠檬酸并用，反丁烯二酸与氢氧化钠反应制成的单钠盐，也用作酸味调味品，还用作合成树脂、媒染剂的中间体。

In the pharmaceutical industry, it is used for the production of drug dimercaptosuccinic acid. The trans maleic acid is neutralized with sodium carbonate to obtain sodium trans butene ([17013-01-3]), and then replaced with ferrous sulfate to obtain iron trans maleate. It is a blood rich iron for small red blood cell anemia. As a food additive, this product is used in cool drinks, fruit candy, jelly, ice cream, etc. it is mostly used in combination with citric acid. The monosodium salt made by the reaction of fumaric acid and sodium hydroxide is also used as sour condiment and as an intermediate of synthetic resin and dye.
