Project Description
Product Description
Fumaric Acid (trans-2-butenedioic acid) is a naturally occurring organic acid found in various plants and lichens, and is an intermediate in the citric acid cycle . It is commercially produced by fermentation of glucose or molasses using Rhizopus species, or by isomerization of maleic acid .
The product is available in food-grade and industrial-grade specifications, with high purity as a key commercial attribute. It is specifically designed for food acidity regulation, feed additive, and industrial applications. As a food acidulant, fumaric acid is roughly three times more acidic than citric acid, allowing smaller quantities to achieve similar taste effects . Its extremely low moisture absorption makes it particularly valuable for extending the shelf life of powdered food products.

Core Functional Benefits
-
Stable pH Buffering & Preservative Effect: It maintains aqueous solution pH stably at 2.25-3.0, forming an acidic environment that inhibits bacterial reproduction, delivering excellent antibacterial and antiseptic effects for food products.
-
High-efficiency Acidulant & Flavor Optimization: With 1.5-fold acidity of citric acid, it reduces additive dosage effectively. Combined with other organic acids, it creates layered and natural fruity flavor without peculiar taste.
-
Antioxidation & Emulsification Stabilization: It assists in inhibiting oxidative deterioration of raw materials, stabilizes water-in-oil emulsifier systems, and extends the shelf life of food and industrial products.
-
Excellent Foam Performance: As an acid component of solid beverage gas-generating agents, it produces fine, uniform and long-lasting bubbles, improving product taste and texture.
-
Low Hygroscopicity & Easy Storage: Food-grade fumaric acid features ultra-low hygroscopicity, not easy to agglomerate, ensuring stable quality during long-term storage and transportation.
Core Application Fields (Highlight Food & Resin Industry)
1.Food & Beverage Industry
Usage: Acidulant for soft drinks, fruit juices, gelatin desserts, pie fillings, jams, jellies, candy, baked goods, and wine .
Recommended addition: According to GB 2760-2024, maximum usage levels include 8.0 g/kg for chewing gum, 3.0 g/kg for bread and pastries, 0.6 g/kg for fruit/vegetable juice drinks, and 0.3 g/kg for carbonated drinks . In the US, fumaric acid is principally used in fruit juices, gelatin desserts, and pie fillings .
Formulators value it for its low moisture absorption, which extends the shelf life of powdered products, and its ability to achieve tartness with smaller quantities than citric acid .
2.Feed Additive Industry
Usage: Acidifier in livestock and poultry feed, particularly for weaned piglets and poultry .
Recommended addition: Typical inclusion rates range from 1-3 g/kg in complete feed . In one study, adding 2% fumaric acid to weaned piglet feed improved daily gain from 289g to 320g and reduced feed-to-gain ratio from 1.87 to 1.71 .
Used in feed formulations as an acidifier and for its role in the tricarboxylic acid cycle, supporting energy metabolism under stress conditions .
3.Industrial Applications
Usage: Unsaturated polyester resins (UPR), alkyd resins, plasticizers, and as a mordant in dyeing .
Recommended addition: According to application requirements. The UPR segment is the second-largest end use for fumaric acid globally, driven by building and construction applications .
