Description

Calcium Tartrate is a white, crystalline powder that serves as a vital calcium source and tartaric acid derivative in various industrial and food-grade applications. Its primary value lies in its role as a functional additive, providing calcium fortification and acting as a sequestrant and firming agent. This compound is essential for manufacturers in the food and beverage, pharmaceutical, and nutraceutical industries seeking a bioavailable mineral supplement and processing aid.

Application

• Food & Beverage Additive: Used as a calcium fortifier in baked goods, nutritional supplements, and beverages, and as a firming agent in canned fruits and vegetables.
• Pharmaceutical Excipient: Functions as a calcium supplement in tablet and capsule formulations, and as a buffering agent.
• Nutraceutical Ingredient: A key component in dietary supplements for bone health and mineral balance.
• Chemical Synthesis: Acts as a precursor or intermediate in the synthesis of other tartrate salts and specialty chemicals.
• Laboratory Reagent: Employed in analytical chemistry and research applications.
• Wine Stabilization: Used in winemaking to help prevent tartrate precipitation (wine diamonds).

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can lead to caking or degradation.
