Product Application of Citric acid monohydrate CAS#5949-29-1
Multi-Scenario Industrial Application Introduction
Citric acid monohydrate is a natural tricarboxylic acid originally extracted from citrus fruits, with versatile functional properties including antioxidation, pH adjustment, chelation and antisepsis, widely applied in pharmaceutical and food processing industries:
Pharmaceutical Industry Usage
It acts as a core pharmaceutical excipient with prominent antioxidant activity. It can effectively stabilize and protect active pharmaceutical ingredients, and serves as a mild preservative to extend the shelf life of medicinal preparations. As a professional pH adjuster, it regulates the acid-base balance of oral syrups, effervescent tablets and ointment formulations. Besides, it can chelate calcium ions in blood samples, functioning as an anticoagulant reagent for clinical blood testing.
Food & Beverage Industry Usage
It is a mainstream food additive and food-grade acidulant for drinks, candies, canned food and dairy products. It can enhance sour flavor, inhibit microbial reproduction and preserve food freshness. Meanwhile, it works as an efficient synergist when mixed with composite antioxidants, greatly improving the anti-oxidation effect of food formulas.
Supplementary Minor Application
It can also be used as chelating agent and pH regulator in daily chemical cleaning products and cosmetic raw material formulations.
