Calcium Citrate E333

Product Overview

Calcium Citrate is a highly bioavailable calcium salt derived from citric acid. It functions as a nutritional fortifier, acidity regulator, and stabiliser used across food, beverage, pharmaceutical, and nutraceutical applications. Known for its excellent solubility and neutral taste, it is ideal for calcium supplementation in fortified foods and beverages supporting bone, joint, and cardiovascular health.

Applications in Food Production

• Beverages & Dairy Fortification: Provides a readily absorbable calcium source for juices, smoothies, dairy, and plant-based milk alternatives. Maintains clarity and stability without affecting taste or colour. Performs well in acidic and pasteurised beverage systems.
  
• Bakery & Snack Foods: Used in fortified flour blends, biscuits, and energy bars to enhance calcium content. Acts as a mild buffer to regulate dough acidity and improve shelf life. Provides structural stability and nutritional enrichment in baked goods.
  
• Nutritional Supplements & Health Foods: A preferred calcium source for tablets, chewables, and powders due to high absorption and gentle digestive profile. Ideal for bone, prenatal, and geriatric nutrition formulations. Offers neutral flavour and excellent compressibility in supplement production.
  
• Dairy & Cheese Processing: Improves calcium retention, texture, and curd firmness in cheese and yoghurt manufacture. Functions as a stabiliser in milk powders and dairy blends. Enhances protein binding and product consistency.
• Beverage Powders & Instant Drinks: Provides instant dispersibility and consistent mineral enrichment in fortified drink powders. Maintains stability and suspension during blending and storage. Suitable for low-pH beverage applications.
• Sauces, Dressings & Processed Foods: Acts as a pH regulator and stabiliser in emulsified and heat-processed foods. Contributes to texture, flavour balance, and mineral fortification. Improves thermal and storage stability in creamy or acidic systems.
• Pharmaceutical & Nutraceutical Uses: Employed as a calcium supplement and excipient in tablets, syrups, and capsules.
  Provides controlled calcium release and is compatible with vitamins and minerals.
  Complies with FCC, USP, and EP pharmacopeial standards.
