Malic Acid

Malic Acid is a naturally occurring organic compound classified as a dicarboxylic acid. It has a sour taste and plays a role in biological processes. It is classified as a dicarboxylic acid due to its two carboxyl groups (-COOH) attached to a four-carbon hydrocarbon chain.

Chemical Formula: C₄H₆O₅

Appearance: Colorless to white crystalline granules or powder.

Uses:

• Food and Beverage Industry: Malic acid is widely used in the food and beverage industry as an acidulant, flavor enhancer, and pH regulator. It is commonly added to food products such as fruit juices, candies, carbonated beverages, confectioneries, and salad dressings to impart a tart or sour taste.

• Pharmaceuticals: In pharmaceutical formulations as a buffering agent, excipient, and disintegrant in tablets and capsules.

• Nutraceuticals and Dietary Supplements: Due to its association with natural fruits and its role in metabolism, malic acid is commonly included in nutraceuticals and dietary supplements. It is marketed as a nutritional supplement to support energy production, muscle function, and overall health.

• Flavoring and Fragrance Industry: Malic acid is primarily used in the flavoring and fragrance industry for its fruity, tart aroma and taste. It is used in the formulation of artificial fruit flavors and fragrances to mimic the taste and scent of fruits, particularly apples.

• Additional Applications: In industrial processes, malic acid may be utilized as a chelating agent, metal cleaner, or pH adjuster. It is employed in metal-cleaning formulations to remove rust and scale from surfaces due to its mild acidic properties.
