Molecular weight: 186.22 (anhydrous)
Properties: white crystals, granules or crystalline powder. Odorless or with a slight smell of propionic acid, monohydrate salt is generally used as a food additive. It is stable to heat and light, and has hygroscopicity. It is easily soluble in water (40%), but insoluble in alcohol and ethers. The pH value of 10% aqueous solution is 8-10.
Under acidic conditions, it produces free propionic acid, which has an antibacterial effect and has no effect on yeast. It is used as an antiseptic and antifungal agent in bread manufacturing.
Natural products exist in Swiss cheese and so on.
