Calcium fumarate

Calcium fumarate (CAS 19855-56-2), also designated E367, is the calcium salt of fumaric acid used as a pH regulator and buffering agent across food, pharmaceutical, and agricultural applications.

It stabilizes acidity in formulations where precise pH control is critical to product performance and shelf life. In food manufacturing, E367 functions as an acidulant and buffering agent in baked goods and beverages.

This additive helps maintain consistent flavor profiles and texture during production. Pharmaceutical formulators use it as a pH modifier in solid dosage forms and as a calcium source in mineral supplementation products.

In animal feed, calcium fumarate supports rumen buffering in ruminant diets, contributing to feed efficiency and digestive stability. It also appears in agricultural formulations where controlled acidity affects nutrient availability.

The compound is essential for product stability in various industrial processes. Calcium fumarate is supplied as a white crystalline powder available in food-grade specification meeting E367 regulatory requirements.

It is also offered in feed-grade and pharmaceutical-grade forms depending on the intended application. Bulk supply is standard for industrial buyers, with smaller packaging available for formulators and QA sampling.
