Anhydrous citric acid at room temperature is a white crystalline powder, odorless and very acidic in color, with a density of 1.542 g/cm3, a melting point of 153-159 degrees and a decomposition temperature above 175 degrees with the release of water and carbon. dioxide Citric acid is easily soluble in water. The solubility is 59 percent at 20 degrees, and the pH of its 2-percent aqueous solution is 2.1. The crystalline form of citric acid varies depending on the crystallization conditions. It erodes slightly in dry air and is hygroscopic in humid air. It can decompose into various products when heated and react with acids, alkalis, glycerin, etc. When citric acid is dissolved in ethanol, it reacts with ethanol to form ethyl citrate.

3. Application of anhydrous citric acid

Anhydrous citric acid is a kind of fruit acid, also called citric acid, which can speed up skin cutin renewal. Its acidic characteristics can be used as flavoring agent, daily chemical products, preservatives, etc. Its main functions are as follows:

Food Additive: Food grade citric acid is an organic acid with a strong sour taste, high in citrus fruits, pineapple, lemon and other fruits, and good taste. It can be added to drinks and food in appropriate quantities, which can improve appetite and taste;

Daily Chemical Products: Food grade citric acid can speed up the body's metabolism, promote skin cutin renewal, and can be used in daily chemical products to help whiten and make skin more shiny;

Preservatives: Edible citric acid is a highly acidic acid. The acidic environment formed by citric acid can inhibit the growth of bacteria to avoid food spoilage and achieve anti-corrosion effect.

Citric acid can also inhibit the clotting of calcium in the blood, soften blood vessels and prevent atherosclerosis. There is no harm in consuming citric acid in an appropriate amount, but long-term consumption of canned food, jam and other processed foods will easily lead to excess citric acid in the body, thereby accelerating the excretion of calcium from the body, and easily causing hypocalcemia.
