Are gums produced in the factory? Quantification of gums isolated from mixed juice and final molasses* [Full subscriber]

Abstract Gummy massecuites in sugar factories are associated with exhaustion problems in pans and inefficient purging in centrifuges. Gums originate in stale cane because of microbial activity during burn/harvest-to-crush delays, especially in the rainy season, but are also thought to be generated by microbial activity within the factory. The proportion of gums generated within the factory is not known. This study investigated the phenomenon of gum formation in the factory by comparing the total amount of gums in mixed juice and in final molasses and considering the fate of gums in a factory. Gums were precipitated with acidified alcohol from…
