Overview

E209 - Heptylparaben

Heptylparaben (E209) is a preservative from the paraben family. It helps stop molds and yeasts from growing, but its legal use in foods varies by country and is uncommon today. Always check your local rules and product labels for the most accurate picture.

E524 - Sodium hydroxide

Sodium hydroxide (E524), also called lye or caustic soda, is a strong alkali used in small, controlled amounts in food processing. It helps adjust acidity (pH), loosens peels on fruits and vegetables, and creates the classic deep-brown crust on pretzels.
