High purity calcium oxide food grade is a refined form of calcium oxide (CaO) that meets strict purity standards for use in food and beverage processing. It typically contains at least 99% CaO, with minimal heavy metals and other impurities. This makes it safe for human consumption when used as a food additive.
What is high purity calcium oxide food grade used for?
In the food industry, it serves multiple functions. It adjusts pH in products like canned vegetables, jams, and dairy alternatives. It also acts as a calcium fortifier in cereals, juices, and health supplements. Additionally, it helps clarify sugar and refine edible oils.
How does it differ from industrial-grade calcium oxide?
Food-grade calcium oxide undergoes rigorous purification and testing to ensure it contains no harmful contaminants. Industrial-grade may have higher levels of heavy metals and is not intended for consumption. The food-grade version must comply with regulations such as FCC (Food Chemicals Codex) or E529.
Why choose a reliable calcium supplier?
When sourcing high purity calcium oxide food grade, working with a reputable calcium supplier ensures consistent quality and safety. Many buyers turn to a calcium manufacturer in China, where advanced production facilities and strict quality control are common. As a leading china calcium salts exporter, these suppliers often provide detailed certificates of analysis and traceability. Always verify the supplier's credentials and request samples before committing to large orders.
What should you look for in high purity calcium oxide food grade?
Check the purity level, typically above 99%, and confirm it is free from contaminants like lead, arsenic, and mercury. Ensure the product comes with a certificate of analysis and meets relevant food safety standards. Also consider particle size and reactivity, as these can affect its performance in your specific application.
常见问题
Is high purity calcium oxide food grade safe to consume?
Yes, when used as intended and within regulatory limits, it is safe. It must meet strict purity standards to ensure no harmful contaminants are present. Always follow dosage guidelines provided by the manufacturer.
How should I store high purity calcium oxide food grade?
Store it in a cool, dry place away from moisture and acids. Keep the container tightly sealed to prevent reaction with carbon dioxide in the air. Proper storage maintains its purity and effectiveness.
What is the difference between food grade and industrial grade calcium oxide?
Food grade is highly purified and tested for safety, while industrial grade may contain higher levels of impurities. Food grade complies with food safety regulations and is suitable for consumption. Industrial grade is not intended for food use.
