A food grade calcium hydroxide manufacturer produces calcium hydroxide (Ca(OH)₂) that meets strict purity and safety standards for use in food processing, such as adjusting pH, clarifying sugar, and processing water. Unlike industrial grades, food grade material must comply with regulations like FCC or E-number E526.
What makes calcium hydroxide food grade?
Food grade calcium hydroxide is defined by its low levels of heavy metals (e.g., lead, arsenic) and other contaminants. It must be produced under hygienic conditions and often carries certifications such as ISO 22000 or FSSC 22000. Purity typically exceeds 95%, and the product is tested for heavy metals and microbial limits.
How do you choose a reliable food grade calcium hydroxide manufacturer?
Look for a manufacturer with a documented quality management system and a proven track record in food and pharmaceutical applications. Verify their certifications, request a Certificate of Analysis (CoA) for each batch, and check if they can provide regulatory support for your target market. A reputable calcium manufacturer will also offer consistent particle size and reactivity.
Why source from a China calcium salts supplier?
China is a major producer of calcium salts, including food grade calcium hydroxide, thanks to abundant raw materials and advanced production technology. Many international buyers work with a calcium supplier in China to access competitive pricing and large-scale supply. However, due diligence is essential: ensure the supplier complies with your local food safety regulations and can provide full traceability.
What certifications should a food grade calcium hydroxide manufacturer have?
Key certifications include ISO 9001, ISO 22000, FSSC 22000, and Halal or Kosher if required. Some manufacturers also hold GMP certificates for pharmaceutical use. Always ask for the latest audit reports and verify the scope of each certificate.
How is food grade calcium hydroxide packaged and shipped?
It is typically supplied in 25 kg multi-wall bags with PE liners, or in bulk bags (500–1000 kg). Proper packaging prevents moisture absorption and contamination. Shipping documents should include the CoA, MSDS, and origin certificate.
常见问题
What is the difference between food grade and industrial grade calcium hydroxide?
Food grade calcium hydroxide has stricter limits on heavy metals and other contaminants, and is produced under hygienic conditions to meet food safety regulations. Industrial grade may contain higher impurities and is not intended for human consumption.
How can I verify the quality of a food grade calcium hydroxide manufacturer?
Request a Certificate of Analysis (CoA) for each batch, check for relevant certifications like ISO 22000, and if possible, arrange for third-party testing. A reputable manufacturer will transparently share test results and audit reports.
Is food grade calcium hydroxide safe for consumption?
When used according to regulations, food grade calcium hydroxide is safe as a processing aid. It is generally recognized as safe (GRAS) by the FDA and approved as E526 in the EU. However, direct consumption of the pure chemical can be harmful and should be avoided.
