Malic acids are D-malic acid, DL-malic acid and L-malic acid. L-malic acid, also known as 2-hydroxysuccinic acid, is a circulating intermediate of biological tricarboxylic acid, which is easily absorbed by the human body, so it is widely used in food, cosmetics, medical and health products and other fields as a food additive and functional food with excellent performance. Malic acid, also known as 2-hydroxysuccinic acid, has two stereoisomers due to the presence of an asymmetric carbon atom in the Chemicalbook molecule. It occurs in nature in three forms, D-malic acid, L-malic acid, and its mixture DL-malic acid. Malic acid is white crystal or crystalline powder, with strong hygroscopicity, easily soluble in water and ethanol. Has a particularly pleasant sour taste. L-malic acid is mainly used in the food and pharmaceutical industries.

Function of L-Malic Acid

1. Acid agent particles by the embedding process, not easy to be delirious, the use of no dust;
2. Prevent chemical reactions with other raw and auxiliary materials;
3. Embedding symmetry, particle size can be customized according to customer requirements;
4. Acid release slow, increase product flavor;
5. As a coating powder, can prevent the product adhesion, extend the shelf life of the product.

Application of L-Malic Acid

1. Malic acid is known as "best food acidity regulator" in biological and nutritional fields. It is widely used in foods such as wines, beverages, fruit juices and chewing gums. It is not only the third food acidity regulator coming after citric acid and lactic acid, but also one of the biggest and most promising organic acids in food industry across the current world.

2. Malic acid can be added in cool drinks, powder drinks, lactic acid drinks, milk drinks and fruit juice drinks to improve their tastes and flavors. Malic acid is capable of gelatinating pectin and therefore can be used for making fruitcakes, jelly fruit juice, puree, etc.
