Compare E202 vs E233, Potassium sorbate vs Thiabendazole

Overview

E202 - Potassium sorbate

Potassium sorbate (E202) is a common preservative that helps stop yeast and mold from growing in foods and drinks. It has a neutral taste, dissolves well in water, and works best in mildly acidic foods. Most food safety agencies consider it acceptable when used as intended.

E233 - Thiabendazole

Thiabendazole (E233) is a synthetic fungicide from the benzimidazole family. In food, it has been used mainly as a post‑harvest surface treatment to stop molds on fruit, rather than as an ingredient mixed into recipes. You’re most likely to encounter it on the peel of certain imported fruits rather than inside packaged foods.
