Sodium propionate powder Raw Materials CAS 137-40-6 Details
Uses and synthesis of Sodium propionate powder
Sodium propionate powder Colorless transparent crystals, granules or white crystalline powder. Sodium propionate CAS 137-40-6 is easy to deliquesce, very soluble in water, soluble in ethanol, slightly soluble in acetone.
Sodium propionate Raw Materials is a kind of food preservative and mold inhibitor allowed by GB2760-1996, used in pastry and cheese; Sodium propionate CAS 137-40-6 can be used alone or with propionic acid and sorbic acid; it can also be used as viscosity inhibitor for beer and so on. Sodium propionate CAS 137-40-6 can be used alone or in combination with propionic acid and sorbic acid; also can be used as inhibitor of viscous substances in beer; feed additive
Sodium propionate CAS 137-40-6 Appearance is colorless transparent crystal or granular crystalline powder, odorless or slightly acetic acid-propionic acid-butyric acid odor. Stable to light and heat, easily deliquesced in humid air.
Applications / Functions of Sodium propionate powder
- Sodium propionate powder Used as preservative, used in pastries, prunes and other anti-mold
- Sodium propionate Raw Materials liquid wet acid preservative, its bacteriostatic effect is affected by the environmental PH. In PH5.0 when the minimum inhibitory concentration of 0.01%, PH6.5 when 0.5%. Sodium propionate Raw Materials in the acidic medium of various types of mold, aerobic bacillus or gram-negative bacilli by the strong inhibitory effect. It is effective in preventing the production of aflatoxin, but almost ineffective against yeast. In addition, it is also used as a food preservative.
- It is used as a masking agent in tanning to improve the alkali resistance of leather and the uniformity of tanning.
Sodium propionate CAS 137-40-6 is also an acidic food preservative, and its bacteriostatic effect is affected by the pH value of the environment. The minimum inhibitory concentration is 0.01% at pH 5.0 and 0.5% at pH 6.5. Sodium propionate CAS 137-40-6 has a strong inhibitory effect on various types of molds, gram-negative bacilli or aerobic bacilli in acidic media.
Physicochemical Property of Sodium propionate powder
Transparent particles or crystals, with special odor.Sodium propionate CAS 137-40-6 deliquesces in humid air. Soluble in water, slightly soluble in alcohol.
Production methodprocess of Sodium propionate powder
Sodium propionate powder is dissolved in neutralization pot, then add propionic acid to neutralize to pH=7~8, neutralization temperature 70~100℃, neutralization time 2~3h. The neutralized liquid is filtered to remove insoluble material, and the clear liquid is concentrated, cooled, crystallized, separated and dried to obtain Sodium propionate Raw Materials.
Propionic acid and sodium carbonate reaction at 80-90 ℃ for 2-3 hours, pH = 7-8, after the reaction, after filtration, spray drying Sodium propionate Raw Materials.
- Dissolve sodium carbonate in hot water, slowly add propionic acid at 70 ℃, and then heated to boiling, pH should be 6.8-7.3, decolorization, filtration, concentration under reduced pressure, cooling, filtration, drying that is Sodium propionate CAS 137-40-6.
- Produced by neutralizing propionic acid with sodium hydroxide or sodium carbonate.
- Sodium carbonate powder is dissolved in neutralization pot, then add propionic acid to neutralize to PH=7-8, neutralization temperature is 70-100℃, neutralization time is 2-3h. Neutralization liquid is filtered to remove insoluble material, and the product is concentrated, cooled, crystallized, separated and dried.
Sodium propionate CAS 137-40-6 is obtained by neutralizing propionic acid solution with sodium hydroxide or sodium carbonate.
