Potassium sorbate as a preservative

[Matty]

Looking through everyone's chew recipes I notice a lot of people using fruit juices to sweeten and flavor their tobacco, ie: apple juice, grape juice, prune juice.... Anyone ever notice in the ingredients if potassium sorbate is being used as a preservative? It might be a "hidden" ingredient in all the recipes that could potentially inhibit mold or fungal growth.

Just putting that out there,

Play safe everyone
