2.1.6.4 Molasses quality
Changes in the quality of molasses are most interesting: extraneous matter decreases the
Clerget purity of molasses. The effect is most marked with cane tops (Fig 2.15), most
probably because of their higher content of reducing sugars. Both cane tops and green
leaves exhibit quadratic curve rather than linear relationship as do dry leaves. However,
cane tops increase the mass of molasses produced % cane (Fig 2.16) with the result that the
loss of sucrose in molasses is high in the case of cane tops (Fig 2.17).
