Food Grade Sodium Propionate with CAS No. 137-40-6
Sodium propionate is a molecular formula of CH3CH2COONa with a relative molecular mass of 96.06. Colorless, transparent crystalline or granular crystalline powder with a slight odor. Monohydrate salt is a colorless crystal and has hygroscopicity. Soluble in water and ethanol, with a solubility of about 100 (15°C) in 10% water, and a pH of 8.5 to 10.5. It has a wide range of antibacterial effects on molds, yeasts and bacteria, and is most active at acidic pH. Used as food preservatives, suitable for preservatives in pastries and as a bread mildewcide. Sodium propionate is almost non-toxic to humans. Food use the same amount of calcium propionate (based on propionic acid). The maximum allowable concentration in cosmetics is 2% (based on propionic acid). Propionic acid as raw materials and neutralized by Sodium Hydroxide and prepared. Sodium propionate is a kind of food preservative that China's GB2760-2011 regulations allow, used in cakes, soy products, etc.; can be used alone or in combination with propionic acid, sorbic acid; can also be used as a viscous substance inhibitors such as beer Feed additives, etc. Appearance is colorless, transparent crystalline or granular crystalline powder, odorless or slightly acetic-propionic acid-butyric acid odor. It is stable to light and heat and deliquescent in humid air.
