Effective of Natural Flocculants on Sugarcane Juice Clarification “A Comparative study”
Subscribe/Renew Journal
One important step in the processing of sugar is the clarification of the sugarcane juice obtained after milling. In practice, the juice is limed so as to produce coagulated suspensions, these settle slowly and it requires a fair amount of time to thicken. Therefore, common practice that natural or synthetic flocculants (or clarifying aids) are added to the limed juice in order to improve settling and compaction of the coagulates, but the use of synthetic flocculant is not permitted in the production of organic food and organic sugar, as only lime can be utilized. In the manufacture of khandsari and gur the cane juice is clarified using the mucilage of plants such as Hibiscus vitifolius, Aloe vera, etc. The present work made an attempt to assess the effect natural flocculants viz Hibiscus vitifolius, Aloe vera on sugarcane varieties selected in Mandya region and results reveals that the natural flocculants have shown good results over the existing commercial flocculant but natural flocculants requires less settling time and turbidity of the clarified juice when compared to commercial flocculant.
