1. Basic properties and properties of sodium propionate
The chemical name of sodium propionate is sodium 3-hydroxypropionate, which is a white crystalline or crystalline powder, odorless or slightly propionic acid odor. It is deliquescent easily, deliquescent in wet air, and soluble in water, slightly soluble in alcohol. The pH of sodium propionate in aqueous solution is 8.5-10.53.
2. The main application of sodium propionate
2.1 Applications in the food industry
In the food industry, sodium propionate is often used for the preservation of pastries, and the amount of use is 2.5g/kg. In addition, it can also be used as an additive for bread and western pastries, with an added amount of less than 2.5g per kilogram. Sodium propionate is mainly used in sweets 14.

2.3 Preservatives and mildewproof agents
Sodium propionate is a food preservative whose bacteriostatic effect is affected by the pH value of the environment. At pH 5.0, the small inhibitory concentration was 0.01%, while at pH 6.5 it was 0.5%. Sodium propionate has a specific effect on preventing the production of aflatoxin, but has little effect on yeast 1.
2.4 Applications in tanning
