5. Description: Critric acid is made from starch by advanced biological technology,It is a white crystalline powder.It can exist either in anhydrous(water-free)from or monohydrate.The anhydrous from crystallizes from hot water,whereas the monohydrate forms when citric acid is crystallized form cold water.When heated above 175℃, it decomposes through the loss of carbon dioxide and water.
