Sodium propionate(Cas 137-40-6) Usage
description |
Sodium propionate is a white crystalline solid, also known as sodium propanoate, which is the sodium salt of propionic acid. It is commonly utilized as a food preservative and flavoring agent due to its ability to inhibit the growth of mold and certain bacteria. Sodium propionate is recognized as generally recognized as safe (GRAS) by the FDA. |
Chemical properties |
It appears as transparent particles or crystal with specific smelly odor. It is easily subject to deliquescence in wet air. It is soluble in water, slightly soluble in alcohol. |
Uses |
Food Preservation: Sodium propionate serves as an effective food preservative, particularly in bakery goods and other products prone to spoilage. It inhibits the growth of molds and certain bacteria, thus extending the shelf life of various food items. In leather-making processes, sodium propionate acts as a binding agent, enhancing the uniformity of alkali resistance and the tanning of leather. Sodium propionate finds application as a preservative in cosmetics, where it exhibits broad antibacterial properties against molds and yeast, contributing to product stability and longevity. |
