Sorbic acid vs Potassium Sorbate

The short answer
They're the same preservative in two forms. Potassium sorbate dissolves easily in water and turns into sorbic acid in food. They share one daily limit and the same low-risk safety profile.

Swapping one for the other

Neither is a reason to avoid a product. If you'd rather skip both, choose fresh bread and refrigerated dips, and freeze what you won't eat within a few days.

Common questions

Which is more natural?

Neither. Both are made synthetically, though sorbic acid was first found in rowan berries.
