Fumaric Acid
ZIO
Fumaric Acid is a naturally occurring organic acid celebrated for its stable performance, pure sour taste, and wide-ranging utility across food, pharmaceutical, feed, and industrial sectors. Our food-grade Fumaric Acid is formulated as a fine white crystalline powder, engineered to meet rigorous quality standards for safe and effective use. As a key acidulant and preservative, it enhances flavor profiles in beverages (such as fruit drinks and carbonated options) and extends the shelf life of bakery products, jams, and candies. Beyond food applications, it serves as a critical pharmaceutical intermediate in drug synthesis, supporting the stability of medicinal formulations. It also functions as a functional feed additive to optimize animal gut health and a reliable raw material in industrial processes like resin production, coatings, and water treatment. Its exceptional heat and light stability ensure consistent results even in high-temperature processing, setting it apart from less durable organic acids.

The core component of our product is high-purity Fumaric Acid (chemical formula C4H4O4), a naturally derived compound with no synthetic additives or impurities. This pure form of Fumaric Acid is what delivers its signature mild yet distinct sourness, making it ideal for food additive applications where taste and safety are non-negotiable. Unlike diluted alternatives, our food-grade Fumaric Acid retains its structural integrity under varying conditions—its resistance to decomposition stems directly from its high-quality, single-ingredient composition. This purity also enhances its compatibility with other food components, pharmaceuticals, and industrial materials, eliminating the risk of unwanted chemical reactions that could compromise performance.
Food & Beverage Advantages: As a premium acidulant, our Fumaric Acid elevates the flavor of beverages and bakery goods without introducing off-notes. Its role as a preservative inhibits microbial growth, keeping products fresh for longer. Its heat stability makes it perfect for baking and pasteurization, ensuring it doesn’t break down during high-heat processes.
Pharmaceutical Value: Serving as a pharmaceutical intermediate, it improves the stability of drug formulations, ensuring medications maintain their potency over time. Its compatibility with various active pharmaceutical ingredients (APIs) makes it a go-to choice for pharmaceutical manufacturers.
Feed Additive Benefits: As a feed additive, it adjusts the pH of animal feed to create a healthy gut environment. This supports the growth of beneficial bacteria, suppresses harmful pathogens, and enhances nutrient absorption—promoting overall livestock wellness.
Industrial Versatility: In industrial settings, it is a key ingredient in resin production, coatings, and papermaking. Its stability and reactivity make it a reliable raw material, while its cost-effectiveness makes it a budget-friendly option for large-scale operations.
Long-Term Reliability: Unlike some organic acids that degrade under light or heat, our Fumaric Acid maintains its properties across batches, reducing waste and ensuring consistent performance for businesses.
Storage Requirements: Store Fumaric Acid in a cool, dry, and well-ventilated area, away from direct sunlight and moisture. Excess humidity can cause clumping, which may hinder its solubility in powder-based applications like solid beverages.
Solubility Tips: It is slightly soluble in cold water but more soluble in hot water. For cold formulations (e.g., iced drinks), pre-dissolve in hot water first to ensure uniform distribution—this prevents uneven sourness in the final product.
Handling Guidelines: Avoid direct contact with eyes or prolonged skin contact. In case of contact, rinse thoroughly with clean water. When handling large quantities, wear gloves to protect skin from potential dryness.
Compatibility Notes: When mixing with other acids (e.g., citric acid) in food formulations, test small batches first. Fumaric Acid has a more concentrated sour profile, so dosage adjustments may be needed to achieve the desired flavor balance.
Is your Fumaric Acid safe for use in food products?
Yes, our Fumaric Acid is a food-grade product that complies with global food additive safety standards. It is widely approved for use in beverages, bakery items, and other food products, ensuring consumer safety when used as directed.
Can Fumaric Acid be used in gluten-free bakery products?
Absolutely. Its heat stability and role as a preservative make it suitable for gluten-free bakery goods (like bread and cookies). It helps maintain freshness and can even improve the texture of gluten-free doughs in some cases.
How does Fumaric Acid compare to other acidulants like malic acid?
Unlike malic acid, Fumaric Acid offers stronger heat stability—making it better for high-temperature processes like baking. It also has a more subtle sour taste, which is less likely to overpower other flavors in complex formulations.
What role does Fumaric Acid play in animal feed?
As a feed additive, it regulates feed pH to support a healthy gut microbiome. This reduces the risk of digestive issues (like diarrhea) and helps livestock absorb nutrients more efficiently, boosting their overall health.
Can I request customized packaging for Fumaric Acid?
Yes, we offer standard packaging (such as 25kg bags or fiber drums) and can provide customized packaging based on your needs—whether for small-scale laboratory use or large-scale industrial production.
