Sodium Propionate Overview
Sodium Propionate is a widely used food additive and feed preservative, recognized for its efficacy as a mold inhibitor and antimicrobial agent. Its chemical designation is CAS 137-40-6, with an EINECS number of 205-290-4. As a white crystalline powder or granules, it is easily recognizable and comes with a chemical formula of C₃H₅NaO₂.
Applications of Sodium Propionate
The primary sodium propionate uses include applications in the food industry and animal feed sectors. It is an effective mold inhibitor in bakery products, extending the shelf life and freshness of breads and pastries. Additionally, sodium propionate application in animal feed preservation helps prevent spoilage and maintains nutritional value.
Sodium Propionate Quality and Purity
Our food grade sodium propionate assures a purity level of ≥ 99%, complying with rigorous testing standards. The acceptable moisture content is ≤ 5%, while the pH of sodium propionate solution ranges between 7.5 and 10.5. To maintain safety, the sodium propionate heavy metals content is restricted to ≤ 10 ppm lead, and sodium propionate arsenic is controlled to ≤ 2 ppm.
Storage and Shelf Life
Proper sodium propionate storage involves keeping the compound in a dry, cool, and well-ventilated area. Containers should be sealed tightly to prevent moisture contamination. When stored correctly, sodium propionate offers a shelf life of 24 months, ensuring long-lasting efficacy.
Packaging Options
Sodium Propionate is available in standard sodium propionate packaging of 25kg bags. For flexible handling, customized packaging options can be provided upon request.
