High purity food grade calcium citrate is a calcium salt of citric acid that meets strict purity and safety standards for use in foods, beverages, and dietary supplements. It is valued for its high bioavailability, neutral taste, and excellent solubility compared to calcium carbonate.
Why Choose High Purity Food Grade Calcium Citrate?
High purity food grade calcium citrate offers superior absorption, especially for individuals with low stomach acid. Its neutral flavor and high solubility make it ideal for fortifying juices, dairy alternatives, and soft chews without affecting taste or texture. Unlike lower-grade calcium salts, it contains minimal heavy metals and meets food safety regulations.
How Is High Purity Food Grade Calcium Citrate Produced?
Production typically involves reacting citric acid with a high-purity calcium source, such as calcium carbonate or calcium hydroxide, followed by filtration, crystallization, and drying. Manufacturers ensure purity by controlling reaction conditions and testing for heavy metals, microbial contamination, and residual solvents. China calcium salts producers are major suppliers, offering various grades to meet global demand.
What Should You Look for in a Calcium Supplier?
When selecting a calcium supplier, prioritize those with certifications like ISO 22000, FSSC 22000, or GMP. Request a Certificate of Analysis (CoA) for each batch to verify purity, particle size, and heavy metal limits. A reputable calcium manufacturer will also provide technical support and consistent supply. Look for transparency in sourcing and third-party testing to ensure safety.
Key Applications in Food and Beverage
High purity food grade calcium citrate is used in a wide range of products, including fortified plant-based milks, energy drinks, chewable supplements, and infant formula. Its neutral taste and high solubility allow for easy incorporation without sedimentation. It also serves as a buffering agent and calcium source in medical nutrition.
Regulatory and Quality Standards
In the EU, food grade calcium citrate must comply with E333, while in the US, it must meet FCC or USP monographs. High purity grades typically contain not less than 97.5% calcium citrate and have tight limits on lead, arsenic, and mercury. Always verify that your supplier provides documentation for regulatory compliance in your target market.
常见问题
What is the difference between food grade and pharmaceutical grade calcium citrate?
Food grade calcium citrate is intended for use in foods and supplements and must meet food safety regulations, while pharmaceutical grade is produced under stricter GMP conditions for medicinal use. Both can be high purity, but pharmaceutical grade often has tighter limits on impurities and requires more extensive documentation.
How do I verify the purity of calcium citrate from a supplier?
Always request a Certificate of Analysis (CoA) for each batch, which should include assay results, heavy metal limits, and microbial testing. Reputable suppliers will also provide third-party test reports and allow audits to confirm their quality control processes.
Is high purity food grade calcium citrate suitable for vegan products?
Yes, high purity food grade calcium citrate is typically vegan-friendly as it is produced from mineral sources and citric acid, with no animal-derived ingredients. However, you should confirm with your supplier that no animal-derived processing aids are used.
