Citric Acid Anhydrous

Citric acid anhydrous is a food-grade water-free form of citric acid produced by fermentation, serving as the most widely used organic acid in food and beverage manufacturing for acidification, flavoring, and preservation. We supply bulk Citric Acid Anhydrous sourced from leading China manufacturers, available in powder and granular forms for global food and beverage producers. Our Citric Acid Anhydrous is widely used in carbonated beverages, jams, fats, oils, and meat products, powder drink mixes and tablet formulations and confectionery and sour candy products.

Introduction

Citric acid anhydrous is produced commercially by submerged aerobic fermentation of carbohydrate substrates, primarily molasses or corn starch hydrolysate, using Aspergillus niger. The fermentation broth is purified through precipitation, filtration, ion exchange, and crystallization to yield high-purity anhydrous crystals.

It is a white, crystalline, free-flowing granular material with a strong, clean, sour taste that enhances flavor profiles across virtually all food and beverage categories. Citric acid anhydrous is highly soluble in water, completely dissociated in solution, and functions as an effective acidulant, chelating agent, and antioxidant synergist. It is the most widely produced and consumed organic acid in the global food industry, with annual production exceeding two million metric tons.

Uses

  • Acidulant and flavor enhancer in carbonated beverages, juices, and sports drinks
  • pH control and preservation in jams, jellies, and canned fruit products
  • Antioxidant synergist and chelating agent in fats, oils, and meat products
  • Effervescent component in powder drink mixes and tablet formulations
  • Acidification and flavor development in confectionery and sour candy products
  • Processing aid in cheese, dairy desserts, and frozen food manufacturing
