DESCRIPTION
Citric acid is a weak organic acid. It is a natural preservative conservative and is also used to add an acidic or sour, taste to foods and soft drinks. In biochemistry, the conjugate base of citric acid, citrate, is important as an intermediate in the citric acid cycle and therefore occurs in the metabolism of virtually all living things.
It is colorless or white crystalline powder and mainly used as an acidulant, flavoring and preservative preservative in foods and beverages. It is also used as an antioxidant, plasticizer and detergent, builder.
Used in food, beverage industries as an acidulous agent, flavoring used in food, beverage industries as an acidulous agent, flavoring agent, and preservative, also used in detergent, electric plating, and chemical industries as an oxidation inhibitor, plasticizer, etc.
Citric acid is an organic acid found a variety of fruits and Acidity regulators vegetables, but it is most concentrated in lemons and limes. It is a natural preservative and is also used to add an acidic (sour) taste to foods and soft drinks. In biochemistry, it is important as an intermediate in the citric acid cycle or Krebs cycle (see the last paragraph) and therefore occurs in the metabolism of almost all living things. Excess citric acid is readily metabolized and eliminated from the body. Citric acid is an antioxidant. It is also used as an environmentally friendly cleaning agent.
