Compare E366 vs E367, Potassium fumarate vs Calcium fumarate

Overview

E366 - Potassium fumarate

Potassium fumarate (E366) is the potassium salt of fumaric acid, a naturally occurring acid found in the body and some foods. It is used as an acidity regulator and flavor enhancer that helps foods taste tart and keeps their pH stable during shelf life. It can be a sodium-free alternative to other acidulants.

E367 - Calcium fumarate

Calcium fumarate (E367) is the calcium salt of fumaric acid, a tart-tasting organic acid used to control acidity in foods. It helps adjust pH, stabilize flavor, and can add a very small amount of calcium to the recipe. Rules for its use vary by country and product type.
