Project Description
Product Description
Fumaric acid, also known as corylic acid or lichenic acid, is a carboxylic acid derived from butene. Fumaric acid tastes like fruit and can be found in Fumaric, Boletus, Lichen and Iceland Nori. Fumaric acid is white granule or crystalline powder, odorless, specific sour taste, strong sour taste, about 1.5 times that of citric acid, so low-concentration fumaric acid solution can replace citric acid. However, because it is slightly soluble in water, it is generally not used alone. It can be used in combination with citric acid and tartaric acid to show the sour taste of fruit.
Food-grade fumaric acid has low hygroscopicity and requires the least amount of neutralization with sodium bicarbonate. When fumaric acid is used as an acidic substance in a solid beverage gas generating agent, the product bubbles are long-lasting and fine. Fumaric acid is colorless, tasteless, and has no toxic side effects. Fumaric acid is commonly used as one of the main ingredients of compound preservatives.
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 (Core High-value Application)
Food-grade fumaric acid (E297) is a globally approved clean-label food additive, widely used as acidity regulator, natural acidulant, preservative and antioxidant auxiliary. It is extensively applied in carbonated drinks, fruit juices, concentrated fruit beverages, solid sparkling beverages, wet noodle products, bread, pastries, biscuits, chewing gum, jam, jelly and canned fruits. It optimizes product sour taste, inhibits microbial growth, delays food oxidation and deterioration, and significantly extends product shelf life. In addition, it serves as a curing accelerator for meat products, improving the taste and texture of marinated and grilled meat products.
2. Resin & Chemical Industry (Main Industrial Application)
Industrial-grade fumaric acid is a key foundational chemical monomer for synthesizingunsaturated polyester resin (UPR). It participates in polymerization reaction to enhance the resin’s mechanical strength, weather resistance and curing performance, widely used in fiberglass products, coating materials, composite materials and industrial casting resin. Besides, it acts as an important intermediate for fine chemicals, applied in the synthesis of pharmaceutical raw materials, optical bleaching agents, plastic additives and oilfield chemical auxiliaries, with stable reaction activity and high industrial utilization value.
3. Pharmaceutical & Fine Chemical Industry
Used as a pH regulator and synthetic intermediate for pharmaceutical preparations, and applied in the research and production of biological agents and nutritional fortifiers, featuring high safety and stable chemical properties.
