citric acid anhydrous
At room temperature, citric acid is white crystalline powder, odorless, extremely sour taste, density 1.542g/cm3, melting point 153-159ºC, decomposition above 175ºC release water and carbon dioxide. Citric acid is easily soluble in water, and its solubility is 59g at 20ºC. The pH of its 2% aqueous solution is 2.1. The crystal morphology of citric acid varies due to different crystallization conditions. It is slightly weathered in dry air and hygroscopic in humid air. It can be decomposed into a variety of products by heating and react with acids, bases and glycerin. Citric acid reacts with ethanol to form ethyl citrate.

Application
Citric acid has a mild and refreshing sour taste, and is widely used in the manufacture of various drinks, soda, wine, candy, Dim sum, biscuits, canned fruit juice, dairy products and other foods. In all organic acid markets, citric acid has a market share of over 70%, and can also be used as a seasoning agent and antioxidant for edible oils. Simultaneously improving the sensory properties of food and promoting the digestion and absorption of calcium and phosphorus substances in the body. Anhydrous citric acid is widely used in solid beverages. Citric acid salts such as calcium citrate and iron citrate are fortifiers that require the addition of calcium and iron ions in certain foods. Citric acid, such as triethyl citrate, can be used as a non-toxic plasticizer to manufacture plastic films for food packaging. It is an acidic and preservative in the beverage and food industries.
