Encapsulated Sorbic Acid is a more potent version of Potassium Sorbate, a commonly used food preservative. It inhibits the growth of microorganisms in food, which increases product shelf life. This encapsulated version is especially well suited for baking applications as the lipid layer that coats the sorbic acid doesn't melt off until the baking process is underway. This allows for the yeast to do its job during the proofing process without interference.
