CITRIC ACID USING CORN
[EIRI/EDPR/4464] J.C.: 2675INR, 2676US$
Citric acid (C6H8O7, 2-hydroxy-1,2, 3-propane tricarboxylic acid), a natural constituent and common metabolite of plants and animals, is the most versatile and widely used organic acid in the field of food (60%) and pharmaceuticals (10%). It has got several other applications in various other fields.
Citric acid is mainly used in food industry because of its pleasant acid taste an its high solubility in water. It is worldwide accepted as "GRAS" (generally recognized as safe), approved by the Joint FAO/WHO Expert Committee on Food Additives. The pharmaceutical and cosmetic industries retain 10% of its utilization and the remainder is used for various other purposes.
A large number of micro-organisms including bacteria, fungi and yeasts have been employed to produce citric acid. Most of them, however, are not able to produce commercially acceptable yields. This fact could be explained by the fact that citric acid is a metabolite of energy metabolism and its accumulation rises in appreciable amounts only under conditions of drastic imbalances. A. niger and certain yeasts such as Saccharomycopsis sp. are employed for commercial production. However, the fungus A. niger has remained the organism of choice for commercial production. The main advantages of using this micro-organism are: (a) its ease of handling, (b) its ability to ferment a variety of cheap raw materials, and (c) high yields.
