Citric acid is a weak organic acid found in leaves and fruits of plants of the genus Citrus (oranges and the like). This compound is a good preservative and natural, not only used as a sour taste enhancer in foods and soft drinks. In biochemistry, citric acid, known as intermediate compounds in the citric acid cycle, which is important in the metabolism of living creatures, so that is found in almost all living creatures. This substance can also be used as environmentally friendly cleaning agent and as an antioxidant.
Citric acid is found in a variety of fruits and vegetables, but found at high concentrations, which can reach 8% dry weight, the lemons and limes.
Citric acid is the chemical formula C6H8O7 (structure shown in the table of information on the right). Acid structure is reflected in its IUPAC name, acid 2-hydroxy-1 ,2,3-propanatrikarboksilat.
Construction:
In the process of citric acid production which, until now commonly used, the culturing of Aspergillus niger were given sucrose to produce citric acid. After the mold was filtered from the resulting solution, citric acid is isolated by his precipitate with calcium hydroxide to form calcium citrate salt. Citric acid-regeneration of the calcium citrate with the addition of sulfuric acid.
Another way isolation from the fermentation of citric acid is extracted using a solution of organic base trilaurilamina hydrocarbon compounds, followed by re-extraction from the organic solution with water.
Purpose:
The first major use of citric acid is as the giver of taste substances and preservatives of food and beverages, especially soft drinks. Code of citric acid as a food additive (E number) is E330. Citrate salt with various kinds of metals are used to provide these metals (as a biological form) in many dietary supplements. Nature of citrate as a buffer solution used as a controller in the solution pH in household cleaners and medicines.
The ability of citric acid to metal makes it useful as a chocolate soap and detergent materials. With her chocolate metal on hard water, citric acid allows the soap and detergent to form foam and works fine without adding hardness remover substance. Similarly, citric acid is used to restore the ion exchange materials used in the removal tool to remove the hardness of the metal ions accumulated in the ion exchange material such as citrate complex.
Citric acid is used in the biotechnology industry and medicine to coat (passivate) pipe machinery, high purity process in lieu of nitric acid, as nitric acid can be a dangerous substance after being used for that purpose, while citric acid does not.
Citric acid can also be added to ice cream to maintain the separation of fat globules. In recipes, citric acid can be used as a substitute for orange juice.
