D-苹果酸应用在食品、医药、日用化工等行业，用作手性添加剂、缓冲剂、调味剂、固化剂。
D-Malic Acid is used in the food, pharmaceutical, daily chemical and other industries as a chiral additive, buffer, flavoring agent, and curing agent.
(1) In the food industry, D-Malic Acid is used to process and prepare beverages, liqueurs, and juices. It is also used in the manufacture of candies and jams, and has an antibacterial and preservative effect on food. It can also be used as an acidity regulator in beverages, juices, jams, candies, yogurt, wine and other foods. It can adjust the pH value of food, enhance the sourness and taste of food, and also play a role in preservation and preservation.
(2) In the pharmaceutical industry: D-Malic Acid is an extremely important four-carbon organic chiral source, which is used in the fields of chiral drugs, chiral additives, and chiral auxiliary agents. As an optically active organic acid, it plays an irreplaceable role in the asymmetric synthesis of certain chiral compounds; it is a selective α-amino protecting agent for amino acids, and is used to prepare chiral compounds of various amino acids.
(3) Application in daily chemical industry: D-Malic Acid is a good complexing agent and ester agent, used in toothpaste formulation, tooth cleaning tablet formulation, synthetic fragrance formulation, etc. It can also be used as a component of deodorant and detergent.
(4) Application in tobacco industry: D-Malic Acid can improve the flavor of tobacco.
