Calcium Propionate (CAS No. 4075-81-4) is an organic acid salt preservative widely used for mold inhibition and shelf-life extension in food and feed applications. It effectively suppresses the growth of molds and certain aerobic spore-forming bacteria while not inhibiting yeast activity under normal usage conditions, making it especially suitable for bakery and fermented products.
Our calcium propionate is supplied in Food Grade and Feed Grade, available in powder, granular, and spherical granule forms. The product features stable quality, clearly defined technical specifications, and full batch traceability, meeting the requirements of GB, FCC, and E282 standards.
Calcium propionate appears as a white crystalline powder or granules, is odorless or has a slight characteristic odor, and is stable to heat and light. It is readily soluble in water and maintains consistent performance during processing and storage.
Technical Support Ensure compliance and safety with our comprehensive product documentation.
Calcium Propionate (CAS No. 4075-81-4) is an important organic acid salt preservative with effective antifungal and antimicrobial properties. It is widely used in food, feed, cosmetics, and related industrial applications.
Calcium propionate shows strong inhibitory effects against molds and certain aerobic spore-forming bacteria responsible for food spoilage, while it does not inhibit yeast activity under normal usage conditions. This makes it particularly suitable for fermented bakery products such as bread and cakes.
Our company offers a long-term and stable supply of calcium propionate in different grades and specifications, including food grade and feed grade products. With consistent quality, clearly defined parameters, and complete technical documentation, our products are suitable for both domestic and international markets.
