Through this period of understanding, I believe you are no stranger to fumaric acid, but for customers who want to know more about this product, these contents are not enough. Today, I will share the knowledge about the function of fumaric acid with you, hoping to arouse your attention and let you have a deep understanding of fumaric acid. In this way, you can also have a clear idea when purchasing fumaric acid. I hope it will be helpful to you. Let's see the following details:

在食品中主要用于肉制品、鱼肉制品加工等。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. Fumaric acid can be used as acidity regulator, acidifier, adjuvant, pickling accelerator and perfume. This product has a strong buffer effect to keep the water solution at pH 3.0, and plays an important role in mold prevention. At the same time, it has astringency, is one of the sour solid acids, and has low absorption rate, which helps to extend the shelf life of powder products. When fumaric acid changed to sodium fumarate, the water solubility and flavor were better

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。

Fumaric acid is used in the production of 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 of styrene and fumaric acid is the raw material for manufacturing FRP, and the plasticizer made of fumaric acid can be used in vinyl acetate latex in contact with food.

该品是医药和光学漂白剂等精细化学品中间体，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。

This product is the intermediate of fine chemicals such as medicine and optical bleaching agent. It is used in the production of drug dimercaptosuccinic acid in the pharmaceutical industry. Sodium fumarate ([17013-01-3]) is obtained by neutralizing fumarate with sodium carbonate, and then iron fumarate is obtained by replacing it with ferrous sulfate. It is a blood rich iron used for small red blood cell anemia. As a kind of food additive, it is used in cool drink, fruit sugar, jelly, ice cream and so on. Most of them are used together with citric acid. The monosodium salt made by reaction of fumaric acid and sodium hydroxide is also used as sour condiment. It is also used as the intermediate of synthetic resin and dyeing agent.
