Tartaric Acid

Whatsapp Order

Tartaric Acid is a naturally occurring organic acid found in many plants, particularly grapes. It is widely used in the food, pharmaceutical, and chemical industries due to its acidic properties and ability to act as a chiral building block in synthesis. This crystalline acid enhances flavor, stabilizes products, and serves as a key ingredient in baking powders, effervescent tablets, and various industrial applications.

Description

Primary Uses
Food Industry
Acidulant: Used to impart tartness and acidity in beverages, candies, and baked goods.

Leavening Agent: Combined with baking soda to produce carbon dioxide for rising in baking powders.

pH Adjuster: Maintains desired acidity levels in processed foods and beverages.

Stabilizer: Prevents crystallization in syrups and jams.

Pharmaceutical Industry
Effervescent Tablets: Acts as an acid component in tablets that dissolve with effervescence.

Chiral Agent: Used in the synthesis of pharmaceuticals due to its stereochemical properties.

Antioxidant: Helps stabilize active ingredients in formulations.

 

Secondary Uses
