Sodium Propionate CAS 137-40-6

Short Description:

Sodium  Propionate CAS 137-40-6

Colorless transparent crystals, particles, or white crystalline powders. Odorless or slightly propionic acid odor. Easy to deliquescent, highly soluble in water, soluble in ethanol, and slightly soluble in acetone.


Sodium propionate is a food preservative and mold inhibitor allowed to be used in accordance with GB2760-1996 regulations in China, and is used in pastries and cheese; Can be used alone or in combination with propionic acid and sorbic acid; It can also be used as an inhibitor of viscous substances such as beer; Feed additives, etc. The appearance is colorless transparent crystalline or granular crystalline powder, odorless or slightly odorous with acetic acid propionic acid butyric acid. Stable to light and heat, easily deliquescent in humid air. Easy to dissolve in water (100 at 15 ° C, 150 at 100 ° C), soluble in ethanol (4.4 at 15 ° C, 8.4 at 100 ° C), slightly soluble in acetone (0.05 at 15 ° C), most active under acidic conditions, producing free propionic acid and having antibacterial effects. It has a wide range of antibacterial effects on molds, yeast, and bacteria, but is ineffective on yeast. Its antibacterial properties are the same as propionic acid. It can be used as an antiseptic and mildew inhibitor for cakes, bean products, dumpling skins, Wonton skins, raw cut noodles, cheese, etc. In the processing technology of canned yangmei, it is used to soak yangmei. Used in beer production to suppress the formation of unfavorable viscous substances.

In the food industry, it is used as a leavening agent, dough conditioner, buffering agent, tissue improver, curing agent, nutritional supplement, chelating agent, etc. As a leavening agent for baked goods and pastries; Yeast promoter, buffer, pectin curing agent (gel effect) for bread and biscuit; Tissue improvers for yeast based meat products. Sodium propionate is used as a food preservative and mold inhibitor, and can be used alone or in combination with propionic acid and sorbic acid. Because it is alkaline, it is more suitable for pastry making than calcium propionate. Propionate salts are of great significance for the preservation of baked goods such as bread, pastries, and biscuits, because the ionization constant of propionic acid is small, so it still has a good effect under alkaline conditions. Used for brewing, it can increase saccharification power and improve beer fermentation ability; Used as a printing agent for viscous substances or as a feed additive.
