Product Description
Potassium benzoate, in the form of white crystal, is widely used as an antimicrobial preservative in various beverages, foods, and even some pharmaceutical products. Its effectiveness as a preservative is influenced by the pH level, with the highest efficacy observed at pH 4.5 or below. However, when the pH is low, uncharged benzoic acid may impart a subtle but detectable taste in food items.
As low sodium content becomes more desirable in various applications, potassium benzoate is being utilized more as a substitute for sodium benzoate. The shift towards potassium benzoate usage is driven by the need for a healthier alternative that will meet consumer preferences.
In the treatment of hypokalemia, potassium benzoate has been employed therapeutically.
Food manufacturers often use potassium benzoate, a chemical preservative that is the potassium salt of benzoic acid. This preservative is employed to maintain the quality and extend the shelf life of various food products. In some cases, potassium benzoate is chosen as an alternative to sodium benzoate to reduce the sodium content in the food.
Specification
White Crystal Potassium Benzoate
Potassium benzoate is a versatile chemical compound that exists as a white granule, flake or crystalline powder. It is characterized by its scentless nature, with only a faint odor that can be hardly detected. The compound has a relatively low melting point within the range of 121.5ºC-123.5ºC. Despite its solid form, potassium benzoate is quite soluble in both water and ethanol. With these properties, the compound can be utilized for various industrial and food processing applications.
