Inhibition of oligo- and polysaccharide formation during sugar cane deterioration.

Oligosaccharides and polysaccharides arising from the metabolic activity of microorganisms in sugarcane between harvesting and crushing seriously diminish process efficiency and raw sugar quality. Several disinfectants have been tested for prevention of cane deterioration but their use has been restricted by poor availability and high cost. The performance of the new non-toxic chemical Ifopol was tested in order to determine the required dosage for use in spraying cane after mechanical harvesting. Ifopol is a mixture of amines of varying degrees of alkylation obtained via the Maillard reaction. Sugarcane cv. Ja.60-5 was sprayed with solutions containing 100 p.p.m. cetyl trimethylammonium bromide (CTAB) or 10-1000 p.p.m. Ifopol; controls were sprayed with water. Once treated, the cane was allowed to remain in the field and was sampled daily. Oligosaccharides, polysaccharides, alcohol and microbial counts were determined in juice samples. Graphs show that the formation of oligosaccharide, polysaccharide and alcohol in green and burned cane was inhibited by 10 p.p.m. and 100 p.p.m. Ifopol, respectively, while in the field, 100 p.p.m. CTAB only partially inhibited the formation of oligosaccharides and polysaccharides. The inhibition by Ifopol was effective for more than 3 days and the disinfectant remained stable in 10 p.p.m. solution for at least a year. Trials on Ifopol spraying of burned cane as it was loaded into rail wagons at the dry-cleaning station showed that treated cane did not exhibit any additional formation of higher sugars. Ifopol is a low-cost product and may be obtained from final molasses.
