Potassium Sorbate


What is Potassium Sorbate?

A mild food preservative commonly used in the baking industry.

Origin

Potassium sorbate is produced by combining potassium hydroxide and sorbic acid to create a potassium salt.

Function

The main function of potassium sorbate is to inhibit the growth of mold, yeast, and microbes, in turn increasing shelf life of food products.

Application

Because of the effect of potassium sorbate on yeast cells, the food preservative is not suitable for bread baking.  Though it is typically utilized in chemically-leavened products (dry blended with the flour) at a level of 0.03% to 0.4% of the batter weight.
