Product Introduction
DL-Tartaric Acid occurs as a colorless crystal or white crystalline powder (anhydrous form: white granules or powder), odorless, with a natural sour taste, and stable in air. It is widely used across the food, pharmaceutical, chemical, and light industries, primarily as a raw material for manufacturing tartrate salts such as antimony potassium tartrate and potassium sodium tartrate.
As a versatile food acidulant, DL-Tartaric Acid provides a clean and refreshing acidic taste while helping regulate pH and improve the overall flavor profile of food and beverages. It is commonly used in beverages, confectionery, bakery products, processed foods and other formulations where reliable acidity control is required..

Functions and Usages
DL-Tartaric Acid is valued for its sour profile — about 1.3 times stronger than citric acid — which makes it a preferred acidulant for grape juice and other beverages. Typical uses include:
- Sourness agent and flavoring in food and beverages: soft drinks, candy, fruit juice, sauces, cold dishes, and leavening/baking powder blends
- Beer foaming (vesicant) agent in brewing
- Raw material for tartrate salts used in the pharmaceutical and chemical industries
- Auxiliary agent in tanning (leather), photography, glass, enamel, and telecommunications equipment manufacturing
