PRODUCTION of E202 (POTASSIUM SORBATE):
E202 (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.

HOW DOES E202 (POTASSIUM SORBATE) WORK AS A PRESERVATIVE?
E202 (Potassium Sorbate) is an inhibitor of both yeasts and moulds, also active for several bacteria but less effective.
It is the sorbic acid (active form) that has the inhibitory activity which is generated after the ionization of E202 (Potassium Sorbate) in water.
E202 (Potassium Sorbate) inhibits microbial growth by changing the cell membrane morphology, integrity and function and then disrupting the transport functions and metabolic activity.
This mechanism of preservation is similar to sodium benzoate, but different with that of nisin and natamycin.

HOW IS E202 (POTASSIUM SORBATE) MADE?
E202 (Potassium Sorbate) can be commercially synthesized by neutralizing sorbic acid (E200, also a food preservative, can be naturally found in berries, but the commercial one is made from chemical synthesis) with potassium hydroxide.
Here is the brief four steps manufacturing process:

*Condensation reaction:
obtain polymeric ester of 3-hydroxy-4-hexenoic acid by the condensation between ketene and crotonaldehyde.
The following is the reaction equation: H2C=C=O + CH3–CH=CH–CHO = CH3CH=CH−CH=CH−COOH

*Decomposition:
decompose the polyester to produce sorbic acid.

*Purification:
through activated carbon, distillation, recrystallization or other processes.
Neutralization with potassium hydroxide.

PURPOSES OF E202 (POTASSIUM SORBATE):
E202 (Potassium Sorbate) serves two purposes:
When active fermentation has ceased and the wine is racked for the final time after clearing, E202 (Potassium Sorbate) renders any surviving yeast incapable of multiplying.
Yeast living at that moment can continue fermenting any residual sugar into CO2 and alcohol, but when they die, no new yeast will be present to cause future fermentation.

Solubility
E202 (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 – E202 (Potassium Sorbate) (solubility 67.6g/100ml at 20 °C) as a preservative in food.

PH
E202 (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 E202 (Potassium Sorbate) increases as the pH decreases.

E202 (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, E202 (Potassium Sorbate) will also ineffective if pH above 7.0.

E202 (Potassium Sorbate) is a preservative used in different packaged foods to help prevent spoilage by microorganisms — namely fungi, such as yeast or mold — and certain bacteria.
“E202 (Potassium Sorbate) is used to help make food safe by curbing microbial growth,” says Isabel Maples, MEd, RDN, a dietitian in Haymarket, Virginia.
“It’s there to help extend shelf life.”

E202 (Potassium Sorbate) comes from sorbic acid, naturally found in the berries of the mountain ash tree and first used by the French in the 1850s to prevent mold growth in various foods.
