Citric Acid Monohydrate CAS#5949-29-1

Citric acid monohydrate happens as colorless or translucent crystals or as a white crystalline, efflorescent powder. It is odorless and has a robust acidic taste. The crystal shape is orthorhombic. monohydrate crystals lose water of crystallization in dry air or when heated to about forty to 50℃. Citric acid monohydrate softens at 75℃ and melts at about 100℃. It serves as a herbal preservative and is many times utilized to make contributions an acidic or bitter style to meals and gentle drinks.
Citric acid monohydrate acts as a preservative and antioxidant. It is additionally used as an acidulant, flavoring agent and antistaling agent in fruit drinks, candy, cookies, biscuits, canned fruits, jams, and jellies. It differs from different varieties of citric acid through having a moisture share ranging from 7.5-9.0.
