Introduction
Citric acid is an important organic acid, also known as citrate, colorless crystals, often contain a molecular crystal water, odorless, strong acidity, soluble in water.
Citric acid is an important compound in the process of converting fats, proteins and sugars into carbon dioxide.
These chemical reactions are the central of almost all metabolic reactions, and provide energy for higher organisms. Hans Adolf Krebs won the 1953 Nobel prize in physiology or medicine for his discovery of these reactions. This series of reactions is known as “the citric acid cycle”, “the three carboxylic acid cycle” or “the Krebs cycle”.
The formula for citric acid monohydrate is C6H8O7 ? H2O, it mainly used as a sour agent of food and beverage industry, flavoring agents and preservatives. It also used as antioxidant, plasticizer and detergent in chemical industry, cosmetic industry and washing industry.
