POTENTIAL OF PAKISTANI CULTIVATED APPLE POMACE AS A SUBSTRATE FOR CITRIC ACID PRODUCTION VIA SOLID STATE FERMENTATION
Faheem Akhtar Shaikh
Abstract
Citric acid is one of the most valuable organic acids which has found its use in various chemical industries like Pharmaceutical and Beverage. Not only this, but it is also an important additive as well. It is estimated that worldwide demand for citric acid has reached 1.7 million tons per year which keeps on the rise every year [1]. Pakistan, despite huge demand, imports citric acid from China and spends a lot of money which could otherwise be reduced greatly if citric acid is produced domestically. In 2008, Pakistan spent 12.2 Million Dollars on the import of citric acid from China [2]. The present study aimed to find the potential of pomace separated from Pakistani cultivated apple as a suitable substrate for citric acid production. Aspergillus Niger (NRRL 567) strain was used to produce citric acid from apple pomace using solid state fermentation. All the experimental work, analysis and optimization were accomplished at Advanced Research Laboratory, Zoology Department, GC University, Faisalabad.
