CITRIC ACID FROM MOLASSES
CODE NO. 5125
Citric acid was first isolated from lemon juice and crystallised as a solid by Scheele in 1784. It is found as natural constituent of citrus fruits, pine apples, peaches, figs and other fruits and tissues. The citric acid extracted from these products is known as a"natural citric acid" in contrast to "fermentation citric acid" lemons, limes and pine apples are the principle sources of natural citric acid, which is produced chiefly in Italy, especially Sicily, and also in California, Hawai and the West Indies.
It has made the United States self sufficient in respect to the citric acid supply and greatly changes the commerce of the world in citric acid and calcium citrate.
Recent developments in the citric acid fermentation include the change from the older established shallow pan method to a deep tank submerged method.
A group headed by S.M. Martin of the National Research laboratory of Canada has been especially active in the development of the submerged production of citric acid from ferrocyanide-treated beet molasses by Aspergillus Niger.
In Russia, Imshenetskiietal through the use of ultraviolet radiation, obtained an A. Niger mutant that produced 16-22% more citric acid than parent strain, which is used in Commercial production of this product. The mutant strain produced 25-30% less mycellium than the parents yet it consumed 26-51% more sucrose per gram of dry mycellium. The yield of citric acid from the sugar consumed varied form 57-74%.
