Abstract
Five samples of molasses collected from Sudanese sugar factories namely Guneid, Half, Sennar, Assalaya and Kenana, were analyzed for physico- chemical characteristics and some microbiological features to see their suitability for fermentation purposes, with emphasis on ethanol production. The results showed that the range of total soluble solids (T.S.S.) in the five samples of molasses was 80.3- 87.7% and the total sugar range was 40.1- 50.0%. El-Guneid molasses contains the highest level of T.S.S. and total sugars, whereas Assalaya molasses contains the lowest level of T.S.S. and total sugars which is similar to Sennar molasses in the latter. With reference to the undesirable features of molasses, the results revealed high level of mud in molasses of both Sennar and Kenana (11%) beside New Halfa (10.5%), and high level of lead (Pb) in molasses from Assalaya (13 ppm). The microbiological features of all molasses were quite satisfactory. Accordingly, molasses from El- Guneid may be considered the best, while molasses of Sennar and Kenana need certain treatment to make them more suitable for fermentation purposes especially for ethanol production.
