Product Introduction

Citric Acid Anhydrous – High Purity Food & Industrial Grade Supplier

1. Product Introduction

Citric Acid Anhydrous (CAS: 77-92-9, E330) is a water-free, high-purity organic acid produced via advanced microbial fermentation of natural carbohydrate raw materials such as corn starch and molasses. It appears as white, odorless crystalline powder with a refreshing sour taste, featuring excellent water solubility, stable chemical properties and strong chelating ability. Different from citric acid monohydrate, this anhydrous version contains no crystal water, delivering higher concentration, better stability and wider adaptability for high-standard food, pharmaceutical, cosmetic and industrial manufacturing scenarios. As a globally recognized safe food additive and industrial chemical, it complies with mainstream international standards including FCC, USP, BP and E330 food grade specifications, serving as a core acidulant, pH regulator, preservative and chelating agent for global industries.
