ABSTRACT :
Following previously established sample-handling guidelines for reliable results (analysis within 3 h of samples kept in sealed plastic bags to avoid evaporation), 22 bagasse samples were taken from the 6th mill, and sucrose % bagasse was determined (2 h later at 3 locations) by up to 5 methods currently used in the sugar industry: hot digestion, Tecnal 1, Tecnal 2, Australian and South African. Mean (2.66-3.28), minimum (0.81-2.34), maximum (4.28-5.98) and CV (19.7-42.7) are tabulated, indicating that the Tecnal methods were less reliable than the others. Postharvest deterioration was monitored (analysis for polysaccharides after 1, 2 and 3 days) in green and burned samples of the commercial cultivar MZC 74-275 and of 2 promising varieties (CC 84-75 and CC 85-96), treated or not with sodium benzoate (1 g/litre). Tabulated results show great differences between the 3 varieties.
