Maleic Acid

Maleic acid is a dicarboxylic acid used primarily as a chemical intermediate and pH adjuster in food processing, as well as in the production of fumaric acid and various food-grade esters. We supply bulk Maleic Acid sourced from leading China manufacturers, available in powder form for global food and beverage producers. Our Maleic Acid is widely used in the production of fumaric acid for food applications, specific processed food manufacturing, food-grade resin and coating production, food-approved emulsifiers and stabilizers and oil well treatment and industrial cleaning applications.

Introduction

Maleic acid is the cis-isomer of butenedioic acid, produced industrially by the catalytic oxidation of benzene or butane to maleic anhydride, followed by hydration. It is a white, crystalline solid with a strong acidic taste and is highly soluble in water.

While maleic acid itself has limited direct food applications compared to its trans-isomer fumaric acid, it serves as an important intermediate in the synthesis of food-grade chemicals and additives. In food processing, maleic acid is used in controlled quantities as a pH adjuster and acidulant in specific applications. The ingredient is also employed in the production of food-contact materials including resins and coatings used in food packaging.

Uses

  • Chemical intermediate in the production of fumaric acid for food applications
  • pH adjuster and acidulant in specific processed food manufacturing
  • Raw material for food-grade resin and coating production
  • Synthesis intermediate for food-approved emulsifiers and stabilizers
  • Acidifying agent in oil well treatment and industrial cleaning applications
  • Starting material for production of succinic acid and specialty chemicals
