Citric Acid a weak organic acid Purity: 99.5%-101% 30~100mesh BP98/EP/FCC QC:ISO9001:2008 / KOSHER / HALAL

citric acid:

Properties:

At room temperature, it is a white crystalline powder. It can exist either in an anhydrous (water-free) form or as a monohydrate. The anhydrous form crystallizes from hot water, whereas the monohydrate forms when citric acid is crystallized from cold water. The monohydrate can be converted to the anhydrous form by heating it above 74 c. Citric acid also dissolves in absolute (anhydrous) ethanol (76 parts of citric acid per 100 parts of ethanol) at 15 degrees celsius. In chemical structure, citric acid shares the properties of other carboxylic acids. When heated above 175 c, it decomposes through the loss of carbon dioxide and water.

Application:

is mainly used as an acidulant, flavorant, preservative in foods and beverage. It is also widely used in pharmaceutical, chemical and detergent industries.
