Description

Calcium Tartrate is a white, crystalline powder derived from tartaric acid, a natural organic acid. This compound is valued for its role as a calcium source and tartrate donor in various industrial and food-grade applications. It is primarily utilized in the food and beverage, pharmaceutical, and nutraceutical industries. Its controlled purity and consistent quality make it a reliable ingredient for formulators seeking specific functional properties.

Application

• As a calcium fortification agent in dietary supplements, functional foods, and beverages.
• Functioning as a firming agent and pH regulator in processed food products, particularly in canned vegetables and jellies.
• Used as a starting material or intermediate in the synthesis of other tartrate salts and fine chemicals.
• Employed in pharmaceutical formulations as an excipient or a source of bioavailable calcium.
• Application in baking powders as a slow-acting acid component.
• Potential use in biodegradable materials and specialty chemical research.

Quality Control

Our Calcium Tartrate is manufactured under a stringent quality management system. We offer grades suitable for food and technical applications, with specifications aligned with industry standards such as FCC (Food Chemicals Codex). Every batch is tested to ensure consistent purity, identity, and safety. A Certificate of Analysis (COA) detailing specific test results is provided with each shipment.

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). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption and caking.
