PRODUCTION of POTASSIUM SORBATE:
Potassium sorbate is produced industrially by neutralizing sorbic acid with potassium hydroxide.
The precursor sorbic acid is produced in a two-step process via the condensation of crotonaldehyde and ketene.

PROPERTIES of POTASSIUM SORBATE:
*Appearance
Potassium Sorbate is a crystal white powder, granular or spherical/pellets with neutral taste and odor.
Potassium Sorbate is easy to absorb water and expired if exposed to humid air.


*Solubility
Potassium Sorbate is freely soluble in water and soluble in ethanol.
As the solubility of sorbic acid is very low in water (0.16g/100ml at 20 °C), as this result, it is usually made into its soluble potassium salt – potassium sorbate (solubility 67.6g/100ml at 20 °C) as a preservative in food.


*PH
Potassium Sorbate's antimicrobial effectiveness is in a wide pH range from 3.0 to 6.5, and better under acidic conditions with pH value less than 5-6.
The activity of Potassium Sorbate increases as the pH decreases.

Potassium sorbate is still effective at higher pH ranges, for example, PH 6.5, while sodium benzoate and potassium benzoate almost lost its antimicrobial activity which are effective to only below PH 4.5.
However, potassium sorbate will also ineffective if pH above 7.0.

HOW DOES POTASSIUM SORBATE WORK AS A PRESERVATIVE?
