Comprehensive Guide: Functions, Grades & Packaging of Citric Acid

Citric Acid is an essential organic acid used globally across food, pharmaceutical, cosmetic, and industrial sectors. Known for its high solubility, mild acidity, and excellent chelating ability, it is produced via microbial fermentation to achieve high purity and consistent quality.

There are two major commercial grades:

Food Grade (FCC/E330) for beverages, confectionery, dairy, and processed foods.

Industrial Grade for detergents, metal cleaning, water treatment, and descaling applications.

Citric acid enhances flavor, regulates acidity, stabilizes color, prevents oxidation, and extends shelf life in food and beverage applications. It also acts as an excipient in pharmaceutical products and a pH-adjusting agent in cosmetics.

For industrial processes, citric acid provides environmentally friendly cleaning performance and is widely used in descaling, rust removal, electroplating, and biodegradable detergents.

We offer multiple packaging options including 25 kg bags, jumbo bags, palletized shipments, and OEM branded packaging for distributors.
