DL-malic Acid raw Materials powder DL-malic Acid
Product Overview:
Malic acid, also known as 2-hydroxysuccinic acid, is a dicarboxylic acid with a chemical formula of C₄H₆O₅. The molecule contains an asymmetric carbon atom, so there are two optical isomers and a racemic body. It is one of the intermediates of the tricarboxylic acid cycle, generated by the hydration of fumaric acid and further oxidized to oxaloacetic acid. It exists in fruits such as apples, grapes, and hawthorns. Malic acid was first separated from apple juice and is the source of the sour taste of apple juice, hence its name. It is also used as a food additive.

DL-malic Acid raw Materials powder DL-malic Acid Details
DL-malic Acid powder Usage and Synthesis.
DL-malic acid is a commonly used food additive and flavoring agent, widely used in jelly and fruit-based foods, which helps food absorption and improves appetite. As an acidulant, it can replace citric acid; it is often used as an acidulant, preservative for refreshing drinks, cold foods, processed foods, and a color retainer for fruit drinks. In the non-food industry, it can be used in medicines, cosmetics, metal cleaners, industrial deodorants and buffers, etc. In the textile industry, it is used as an anticoagulant, a raw material for fluorescent whitening agents, etc.
Uses of DL-malic Acid.
Malic acid is an internationally recognized safe food additive used as an acidulant, preservative and pH value regulator. Its sour taste is mild and long-lasting, and its sour taste is 20% stronger than citric acid. It can be used in all kinds of food and used in appropriate amounts according to production needs.
In the food industry, it is used as an acidulant, color retainer, preservative and emulsifier stabilizer for egg yolks, etc. It is also used in pharmaceuticals.
In the food industry, DL-malic acid is used as an acidulant, color retainer, preservative, and emulsifier stabilizer for egg yolk, etc. It is also used in pharmaceuticals. DL-malic acid is used as an acidulant for refreshing beverages (such as lactic acid bacteria beverages, milk beverages, soda, cola), frozen foods (such as fruit dew, ice cream, etc.), processed foods (such as fruit wine, mayonnaise), color retainer, preservative, and emulsifier stabilizer for fruit beverages, etc. It is also used as a raw material for medicines, cosmetics, tooth cleaning liquids, metal cleaners, anticoagulants in the textile industry, and fluorescent whitening agents for polyester fibers.
Synthesis of DL-malic Acid.
Product Methods of DL-malic Acid.
DL-malic acid can be obtained by adding water to fumaric acid or maleic acid under high temperature and high pressure. Dissolve fumaric acid in distilled water, preheat to 50℃ and add to a high-pressure reactor. Heat to 180-199℃, pressure about 1MPa, react for 8h, cool to below 100℃, and press out the reactant.
Vacuum concentrate at 60℃ to precipitate crystals. Then cool, dehydrate and dry to obtain the finished product. The yield is 88%. Another major production method of malic acid is fermentation, which uses mutant yeast to ferment sugars.
