About Citric Acid

Citric Acid is a versatile and widely-used organic acid known for its colorless, odorless crystalline form and distinctive acidic taste. This weak organic acid, also referred to scientifically as propane-1,2,3-tricarboxylic acid, is an essential component in the metabolic pathways of aerobic organisms and serves a multitude of functions across various industries.

In its commercial production, Citric Acid is primarily derived through the fermentation of sugars by specific strains of Aspergillus niger. During this process, the mold is cultivated in a controlled environment on a sucrose and salt solution. The production begins with inoculating a seed tank with Aspergillus niger spores, which are then added to a fermenter containing pasteurized syrup. The fermentation process is carefully monitored with adjustments to pH and nutrient levels, while sterile air is introduced to support the conversion of sugar into Citric Acid. Post-fermentation, the Citric Acid is purified through methods such as lime-sulfuric acid treatment or liquid extraction to ensure its quality.

Citric Acid is renowned for its broad range of applications due to its unique chemical properties. It acts as an effective chelating agent and scale remover in various industrial processes. The presence of three carboxylic acid groups allows Citric Acid to form stable complexes with metal ions, which helps in preventing unwanted deposits and reducing oxidation and corrosion. This property makes Citric Acid invaluable in industries such as boiler maintenance and evaporator systems, where it aids in removing scale deposits and preventing their reformation.

In addition to its industrial uses, Citric Acid is a common ingredient in the food and beverage industry, where it functions as an acidity regulator to enhance flavor and preserve freshness. Its ability to chelate metal ions also contributes to its effectiveness in maintaining product stability and preventing spoilage.
