Calcium oxide high purity food grade is a refined form of calcium oxide (CaO) that meets strict safety and quality standards for use in food and beverage processing. It is commonly used as a firming agent, pH regulator, and nutrient source in products ranging from canned vegetables to baked goods.
What makes calcium oxide high purity food grade different from industrial grades?
Food-grade calcium oxide is produced with tighter control on heavy metals, arsenic, and other contaminants. Unlike industrial grades, it must comply with food safety regulations such as FCC or E numbers, ensuring it is safe for human consumption. This purity is critical for applications where even trace impurities could affect taste, shelf life, or health.
Where is calcium oxide high purity food grade used?
In the food industry, it adjusts acidity in cocoa processing, firms up vegetables during canning, and provides calcium in fortified foods. It also plays a role in sugar refining and as a processing aid in some traditional foods. Beyond food, it is used in pharmaceuticals and dietary supplements where high purity is equally essential.
How do you choose a reliable calcium supplier for food-grade applications?
Look for suppliers with documented quality certifications, such as ISO or FSSC 22000, and ask for a certificate of analysis for each batch. A reputable calcium manufacturer will provide full traceability and consistent purity. Many buyers also source through established china calcium salts distributors who specialize in food-grade minerals, ensuring compliance and stable supply.
What should you consider when buying calcium oxide high purity food grade?
Check the assay level (typically 95% or higher), particle size, and packaging to prevent moisture absorption. Verify that the product is stored and transported under conditions that maintain its integrity. Always request a sample and review the safety data sheet before committing to a large order.
常见问题
Is calcium oxide high purity food grade safe to consume?
Yes, when used according to food regulations, it is safe. It is approved as a food additive in many countries and must meet strict purity limits for heavy metals and other contaminants. However, it is caustic in its pure form and should only be handled as directed.
What is the difference between food grade and industrial grade calcium oxide?
Food grade calcium oxide undergoes additional purification to remove harmful impurities and must comply with food safety standards. Industrial grade may contain higher levels of heavy metals and is not intended for human consumption.
How should calcium oxide high purity food grade be stored?
Store it in a cool, dry place in tightly sealed containers to prevent reaction with moisture and carbon dioxide. Avoid exposure to air, as it can degrade over time. Proper storage ensures it remains effective for its intended use.
