应用
Potassium Benzoate is manufactured primarily for food and beverage use. It is a chemical preservative, which in very low concentrations inhibits the activity of the microorganisms. It is used in carbonated beverages. The shelf life of un-pasteurized cider can be greatly extended by adding potassium benzoate. It is also used as the whistle in many fireworks.
