Food Additive Citric Acid Monohydrate / Citric Acid Anhydrous
CITRIC ACID MONOHYDRATE / ANHYDROUS 99.5%Min
Properties of Citric Acid:
At room temperature, citric acid is a white crystalline powder. It can exist either in ananhydrous (water-free) form or as a monohydrate. The anhydrous form crystallizes from hot water, while the monohydrate forms when citric acid is crystallized from cold water. The monohydrate can be converted to the anhydrous form by heating above 78 °C. Citric acid also dissolves in absolute (anhydrous) ethanol (76 parts of citric acid per 100 parts of ethanol) at 15 °C.
