Calcium hydroxide food grade wholesale refers to the bulk purchase of high-purity calcium hydroxide (also known as slaked lime or hydrated lime) that meets food-grade standards, typically used in food processing, fortification, and pH adjustment. It is a white, odorless powder with the chemical formula Ca(OH)₂, produced by hydrating high-calcium quicklime. Food-grade material must comply with strict purity requirements, such as FCC (Food Chemicals Codex) or E526, ensuring low levels of heavy metals and other contaminants.
What are the main applications of food-grade calcium hydroxide?
In the food industry, calcium hydroxide is used in several key processes. It adjusts pH in products like corn tortillas (nixtamalization), clarifies sugar juice, and fortifies beverages and foods with calcium. It also serves as a processing aid in cocoa, pickles, and some baked goods. Because it is a strong alkali, precise dosing is critical to maintain product safety and quality.
How do you choose a reliable calcium hydroxide supplier?
When sourcing calcium hydroxide food grade wholesale, prioritize suppliers who provide a Certificate of Analysis (COA) for each batch, verifying purity and compliance with food regulations. Many buyers look for a calcium manufacturer with a proven track record in food-grade chemicals, or a calcium supplier that offers consistent particle size and packaging options. Working with a reputable supplier ensures product traceability and reduces the risk of contamination.
What should you consider when buying in bulk?
Bulk purchasing of food-grade calcium hydroxide involves factors like price per metric ton, minimum order quantity, and shipping logistics. Prices vary based on purity, packaging (e.g., 25 kg bags or bulk sacks), and origin. Many wholesale suppliers are based in China, which is a major producer of calcium salts, including calcium hydroxide. However, always verify that the supplier adheres to international food safety standards such as ISO 22000 or FSSC 22000.
How should food-grade calcium hydroxide be stored and handled?
Store calcium hydroxide in a cool, dry place away from acids and moisture. It is hygroscopic and can absorb carbon dioxide from the air, forming calcium carbonate. Use appropriate personal protective equipment (PPE) when handling, as it is a skin and eye irritant. Proper storage maintains its potency and ensures it remains suitable for food applications.

What is the difference between food-grade and technical-grade calcium hydroxide?
Food-grade calcium hydroxide meets stricter purity standards, with limits on heavy metals and other contaminants, making it safe for human consumption. Technical-grade may contain higher levels of impurities and is not intended for food use. Always check for a food-grade certification like FCC or E526.
How is calcium hydroxide used in food processing?
It is used to adjust pH, clarify sugar, fortify foods with calcium, and in traditional processes like nixtamalization for corn tortillas. It acts as a processing aid and can also be found in some pickling and cocoa applications. Its alkaline properties help control acidity and improve texture.
What should I look for in a wholesale supplier?
Look for suppliers who provide a Certificate of Analysis (COA) for each batch, adhere to food safety standards like ISO 22000, and have experience in food-grade chemicals. Reliable suppliers offer consistent quality, clear pricing, and timely delivery. It's also wise to verify their reputation and customer reviews.
