After 1975, while molasses purity had increased by 3 units, the quantity of molasses
produced % cane had only slightly decreased probably due to better clarification. The
increase in sucrose lost in molasses % sucrose in cane was 0.8 unit from 7.4 in 1975 to 8.2
in 2004 as shown in Fig 1.14. With harvesting difficulties, considerable amounts of
extraneous matter found its way into the mills together with a fair amount of immature
