Limit:

1. Sodium propionate liquid wet-acid preservative, its bacteriostasis is affected by environmental PH. The minimum inhibitory concentration was 0.01% at PH5.0 and 0.5% at PH6.5. In acidic medium, it can inhibit all kinds of fungi, aerobic Bacillus or Gram-negative bacilli. It has a special effect on preventing the production of aflatoxin, but almost no effect on yeast.

In acidic medium, it has strong inhibitory effect on all kinds of fungi, Gram-negative bacilli or Aerobic Bacillus. It has a special effect on preventing the production of aflatoxin, but almost no effect on yeast. In the food industry, it can be used for preservation of pastries, using 2.5g/kg (in propionic acid, the same below); in 3%-5% water solution soaking bayberry, the most ambassadorial dosage is 50g/kg. It can also be used as a fungicide for feed.
