Slaked lime calcium hydroxide food grade is a purified form of calcium hydroxide (Ca(OH)₂) that meets strict purity standards for use in food and beverage processing. It is produced by hydrating high-purity calcium oxide and is valued for its alkalinity and minimal impurities.
What is slaked lime calcium hydroxide food grade used for?
In food production, it adjusts acidity, firms textures, and aids in clarifying. It is used in traditional foods like tortillas, pretzels, and some pickles. It also serves as a processing aid in sugar refining and water treatment for beverages.
How is food-grade calcium hydroxide made and tested?
Manufacturers start with selected limestone, calcine it to quicklime, then hydrate it under controlled conditions. The resulting slurry is dried and milled. Rigorous testing ensures heavy metals, arsenic, and lead remain below food safety limits set by authorities like the FDA and EFSA.
Why source from a specialized calcium manufacturer or supplier?
Food-grade compliance demands documented purity and traceability. A reputable calcium manufacturer provides certificates of analysis and follows GMP. Working with an experienced calcium supplier ensures consistent quality and regulatory support. Many buyers also consider other china calcium salts for complementary needs, but food-grade hydroxide requires dedicated supply chains.
