Function of Dl-Malic Acid :
(1) In food industry: it can be used in the processing and concoction of beverage, liqueur, fruit juice and the manufacture of candy and jam etc. It also has effects of bacteria inhibition and antisepsis and can remove tartrate during wine brewing.
(2) In tobacco industry: malic acid derivative (such as esters) can improve the aroma of tobacco.
(3)In pharmaceutical industry: the troches and syrup compounded with malic acid have fruit taste and can facilitate their absorption and diffusion in the body.
Application of Dl-Malic Acid:
Malic acid is an important component of natural fruit juice. Compared with citric acid, malic acid has higher acidity (acidity is 20% stronger than citric acid), but soft taste (high buffer index). Malic acid has a special flavor and does not damage the mouth and teeth. Malic acid is an essential organic acid and an ideal food additive with low calories. When 50% malic acid is shared with 20% citric acid, strong natural fruit flavor can be obtained. Drinks (various cool drinks) : Soft drinks prepared with malic acid to quench thirst and refresh the mouth, with malic acid taste, close to natural juice. Malic acid tastes like natural fruit juice and has natural flavor. Compared with citric acid, malic acid produces lower heat and better taste. Therefore, malic acid is widely used in many kinds of food such as wine, drinks, jam and chewing gum, and it is gradually replacing citric acid. It is one of the organic acids in the world food industry with the largest consumption and good development prospect.
