A food grade calcium oxide manufacturer produces high-purity calcium oxide (CaO) that meets strict safety and quality standards for use in food processing, such as pH adjustment, fortification, and as a processing aid. Unlike industrial grades, food grade CaO must comply with regulations like FCC or E number E529, ensuring low heavy metal content and consistent purity.
What should you look for in a food grade calcium oxide manufacturer?
Choose a manufacturer with certified food safety systems (e.g., FSSC 22000, ISO 22000) and full traceability. They should provide a certificate of analysis (CoA) for each batch, detailing purity, heavy metals, and microbiological limits. A reputable food grade calcium oxide manufacturer also offers technical support and reliable supply chains.
Why does the source of calcium matter?
Food grade CaO is typically derived from high-purity limestone. Manufacturers must control calcination and subsequent processing to avoid contamination. Many buyers also source related products like china calcium salts or work with a broad-spectrum calcium manufacturer to consolidate orders. A dependable calcium supplier ensures consistent quality and timely delivery.
How is food grade calcium oxide used?
It is used in sugar refining, juice processing, and as a dough conditioner. It also serves as a calcium fortifier in some products. Because it reacts with water to form calcium hydroxide, handling requires proper safety measures.
What documentation should accompany each shipment?
Expect a CoA, safety data sheet (SDS), and often a halal or kosher certificate. Some manufacturers also provide allergen and GMO statements. Always verify that the product meets your target market's regulations.
常见问题
What is the difference between food grade and industrial calcium oxide?
Food grade calcium oxide has stricter purity limits, especially for heavy metals like lead and arsenic, and is produced under food safety management systems. Industrial grade may contain higher levels of impurities and is not intended for human consumption.
How do I verify a food grade calcium oxide manufacturer?
Check for food safety certifications such as FSSC 22000 or ISO 22000, and request a certificate of analysis for each batch. You can also ask for audit reports and references from other food industry clients.
Can food grade calcium oxide be used in organic products?
It depends on the organic certification standards. Some organic regulations allow calcium oxide as a processing aid, but you should verify with your certifier. The manufacturer should provide documentation to support organic compliance if needed.
