PROJECT DESCRIPTION
Citric acid or 2-hydroxy-1, 2, 3-propanetricarboxylic acid, HO 2 CCH 2 C (OH) (CO 2 H) CH 2 CO 2 H, is a weak organic carboxylic acid. Citric acid is a white crystalline powder. It can exist either in an anhydrous (water-free) form or as a monohydrate. The anhydrous form crystallizes from hot water, whereas the monohydrate forms when citric acid is crystallized from cold water. The monohydrate can be converted to the anhydrous form by heating above 78°C. Citric acid also dissolves in absolute (anhydrous) ethanol (76 parts of citric acid per 100 parts of ethanol) at 15°C.
Citric acid exists in greater than trace amounts in a variety of fruits and vegetables, most notably citrus fruits. Citric acid is found in many citrus fruits: pineapples, gooseberries, limes, plums, lemons, peaches, oranges, and grapefruit. Lemons and limes have particularly high concentrations of the acid; it can constitute as much as 8% of the dry weight of these fruits (about 47 g/L in the juices).
Citric acid is a natural preservative and is also used to add an acidic, or sour, taste to foods and soft drinks. It is used in soft drinks and in laxatives, bacterial inhabitant, pH adjustment, and as an anti oxidant and cathartics. Its salts, the citrates, have many uses, e.g., ferric ammonium citrate is used in making blueprint paper. Sour salt, used in cooking, is citric acid. Citric acid is employed in pharmaceutical preparations as an acidulant and to enhance the flavour of syrups, solutions and elixirs. Citric acid can also be used to dissolve hard water deposits from shower doors, to remove mild rust stains, remove tarnish from brass and copper and to remove spots and yellowing/browning on carpets and rugs. Citric Acid is available in granular and fine granular particle size.
The major industrial route for citric acid used today is fermentation method that is cultures of Aspergillus niger are fed on sucrose to produce citric acid. After the mold is filtered out of the resulting solution, citric acid is isolated by precipitating it with lime (calcium hydroxide) to yield calcium citrate salt, from which citric acid is regenerated by treatment with sulfuric acid.
Alternatively, citric acid is sometimes isolated from the fermentation broth by liquid-liquid extraction with a hydrocarbon solution of the organic base trilaurylamine, followed by re-extraction from the organic solution by water. It is also produced from fermentation from molasses.
The Indian demand is around 37000tonnes. The present import of citric acid is around 35000 tonnes. The projected demand for citric acid according to analyst is around 44000tonnes by the end of 2013-2014. The global production is around 1.75 million metric tonnes per annum. Taking into account the present demand supply scenario for domestic and global, price trends, new capacities can be created by entrepreneurs.
