Citric acid is an important organic acid, also known as citric acid, colorless crystals, often contains a molecular crystalline water, odorless, and has a strong sour taste, which is easy to dissolve in water. Its calcium is easily dissolved in cold water than hot water. This nature is often used to identify and separate citric acid. Control the appropriate temperature when crystallization can obtain water -free citric acid. In the industry, the food industry, and the makeup industry, there are many uses.
