Calcium Propionate (99%)

Calcium propionate is the calcium salt of propionic acid, with the chemical formula Ca(C2H5COO)2. It is a white crystalline solid with a faint odor of propionic acid. Here are some key points about calcium propionate:

1. Production: Calcium propionate is produced by the reaction of propionic acid with calcium hydroxide or calcium carbonate. The reaction forms calcium propionate and water:

   C2H5COOH + Ca(OH)2 → Ca(C2H5COO)2 + H2O

2. Preservative: Calcium propionate is primarily used as a food preservative to inhibit the growth of mold and bacteria in baked goods and other food products. It helps extend the shelf life of bread, cakes, pastries, and other baked items by preventing spoilage and mold growth.
3. Antifungal Properties: Calcium propionate inhibits the growth of various molds, including common bread molds such as Penicillium spp. and Aspergillus spp. It works by interfering with the metabolism of these microorganisms, disrupting their cellular functions and inhibiting their growth and reproduction.
4. Regulatory Approval: Calcium propionate is generally recognized as safe (GRAS) by regulatory authorities, including the U.S. Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA). It is approved for use as a food additive in many countries around the world.
5. Application: Calcium propionate is typically added directly to dough or batter during the manufacturing process of baked goods. It is effective at low concentrations, typically ranging from 0.1% to 0.5% of the total weight of the flour used. It can also be used as a dusting powder on the surface of finished baked products.
6. Other Uses: In addition to its role as a food preservative, calcium propionate may also be used in animal feed as a mold inhibitor to prevent the growth of mold and extend the shelf life of feed ingredients. It helps maintain the freshness and nutritional quality of animal feed during storage.
7. Safety Considerations: Calcium propionate is generally considered safe for human consumption when used within the recommended limits. However, some individuals may experience allergic reactions or sensitivity to calcium propionate. As with any food additive, it is important to adhere to regulatory guidelines and ensure proper handling and labeling of products containing calcium propionate.
