摘要

Raw and refined sugar solutions were sequentially filtered on Millipore membranes with different pore sizes, ranging from 60 μm to 0.45 μm, and the material trapped on the membrane surfaces examined by electron microscopy. The results showed that filter clogging material was caught on membranes with 1.2 μm pore size or smaller, hi the case of raw sugar solutions, membranes visually appeared to be covered with a uniform coat of light brown color, whereas white sugar solutions may or may not have a small amount of color. Microscopic examination revealed an amorphous, gel-like material coating the membrane and partially embedded in it, completely covering the pores of the membrane. It is felt that this material contributes both color and turbidity during sugar processing and may arise from highly degraded bagacillo in the colloidal range. Filtration studies showed that most refined cane sugar solutions will clog a 0.45 μm pore-size membrane before a solution containing 100 g of sugar can be completely filtered. Enzyme studies showed that enzymes associated with cellulose and hemicellulose degradation improved filtration of raw sugar solutions. Hydrolysis and gas chromatographic examination of the filter-clogging material showed a polysaccharide-rich component that was high in mannose and glucose, indicating a different composition from the soluble indigenous cell wall polysaccharide of cane. A similar material was shown to coat ion exchange resin beads.
