Where is Calcium fumarate used?

• Food manufacturing: acidulant and buffering agent in baked goods and beverages
• Pharmaceuticals: pH modifier in solid dosage forms and calcium source in mineral supplementation
• Animal feed: rumen buffering in ruminant diets for feed efficiency and digestive stability
• Agricultural formulations: controlled acidity affects nutrient availability
• It stabilizes acidity where precise pH control is critical to product performance and shelf life.

Commercial specifications

• Food-grade specification meeting E367 regulatory requirements
• Bulk supply standard; smaller packaging for formulators and QA sampling
