E 202 (Potassium Sorbate) serves two purposes. 
When active fermentation has ceased and the wine is racked for the final time after clearing, 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. 
When a wine is sweetened before bottling, potassium sorbate is used to prevent refermentation when used in conjunction with potassium metabisulfite. 
E 202 (Potassium Sorbate) is primarily used with sweet wines, sparkling wines, and some hard ciders, but may be added to table wines, which exhibit difficulty in maintaining clarity after fining.
Some molds (notably some Trichoderma and Penicillium strains) and yeasts are able to detoxify sorbates by decarboxylation, producing piperylene (1,3-pentadiene). 
The pentadiene manifests as a typical odor of kerosene or petroleum.

To obtain an optimal conservation effect, the POTASSIUM SORBATE should be used along with an adequate dose of sulfur dioxide and a sterile filtration treatment.
The presence of free sulfur dioxide protects the wine from oxidation and from the catabolism of the lactic bacteria on the sorbic acid, preventing the formation of anomalous perfumes (e.g. geranium).
The use of POTASSIUM SORBATE is recommended for wines containing residual sugar which are therefore susceptible to undesired refermentation in the bottle.
The action of sorbic acid and sorbates is not compromised by heat treatments.

E 202 (Potassium Sorbate) Function
The main function of E 202 (Potassium Sorbate) is to inhibit the growth of mold, yeast, and microbes, in turn increasing shelf life of food products.
E 202 (Potassium Sorbate) can effectively inhibit the activity of mold, yeast and aerobic bacteria which can be found in foods, such as cheese, wine, yogurt, dried meats, soft drinks & fruit drinks, canned fruits and vegetables and baked food, but can also prevent the growth and reproduction of harmful microorganisms such as Botox, Staphylococcus and Salmonella.
However,E 202 (Potassium Sorbate) is almost ineffective to the anaerobic Bacillus and acidophilic Lactobacillus and other beneficial microorganisms. 
The inhibition of development is stronger than the bactericidal effect, so can effectively extend the shelf life of food, and maintain the flavor of the original food. 
The preservative effect 5-10 times to another food preservative Sodium Benzoate. 
Some food manufacturers use Potassium sorbate E202 to replace Sodium Benzoate or Parabens.
