Citric acid is also known as sildenafil citrate, colorless crystals. It has a strong sour taste and is easily soluble in water. Citric acid can be used as condiments of many vitamin c products, and also it is more widely used in the food industry. It can be used as a natural cleansing agent in the industrial field, and citric acid is also commonly used to develop films.

Citric acid is an indispensable nutrient metabolism of the body. Its oxidation reaction heat is an important source of energy required to human life. It can be used directly in food, pharmaceutical industry, besides, it used as a reducing agent in printing and dyeing leather. Citric acid is mainly used as an acidic agent, solubilizing agent, buffering agent, antioxidant, fishy odor removal agent, flavor booster, gels, toners, etc. In addition, it also plays an important role in inhibits bacteria, color protection, improve flavor and promote the transformation of sucrose.

Most of the factories are still using calcium carbonate and sulfuric acid solution to extract of citric acid. In addition, research shows the successful of extraction of citric acid by extraction, electrodialysis and ion-exchange.

But there may have industrial hazardous that we may need to pay attention. The concentrated solutions of citric acid has irritation to mucosal.
