houjiang Top Quality Food Additive Citric Acid Monohydrate
Citric acid is one of the most common food preservatives and flavoring additives. It can be found naturally in citrus fruits but is also manufactured. Its name is derived from the fact that it's an organic acid found in many fruits and vegetables, especially citrus fruits. Citric acid is a concentrated powder that is prized for its sour flavor, preservative quality, and ability to act as a pH buffer. For these reasons, citric acid is found on the ingredients list of many foods in your kitchen pantry, including preserves, candy, and crunchy snacks. It is also known as "sour salt" due to its flavor and similar appearance and texture to salt.
Citric Acid Properties:
At room temperature, citric acid 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.
