Product Introduction

Citric Acid Anhydrous is a weak organic acid and is used to add a sour taste to drinks and foods. Citric acid's conjugate base is citrate and an important intermediate in the citric acid cycle in biochemistry.

Citric acid is the world's largest organic acid produced by biochemical methods. Citric acid and its salts are one of the pillars of the fermentation industry and are mainly used in the food industry as acidifier, solubilizer, buffering agent, antioxidant, deodorizer, flavor enhancer, gelling agent, coloring agent, etc.

Function of Citric Acid Anhydrous

1. Food industry

Citric acid is the most biochemically produced organic acid in the world. Citric acid and salts are one of the pillar products of the fermentation industry, mainly used in the food industry, such as sour agents, solubilizers, buffers, antioxidants, Deodorizing agent, flavor enhancer, gelling agent, toner, etc.

2. Metal cleaning

It is widely used in detergent production, and its specificity and chelation play a positive role.

3. Fine chemical industry

Citric acid is a kind of fruit acid. Its main function is to accelerate the renewal of cutin. It is often used in lotion, cream, shampoo, whitening products, anti-aging products, acne products, etc.
