An adverse consequence of the exposure of sugar juice to high-temperature steam and vapor in the multiple-effect evaporator is sucrose inversion loss, which converts sucrose to glucose and fructose.

WebExplanation: Single effect evaporators are better than multiple effect because expensive materials of construction can be used as is the case with corrosive feeds, and when the vapour is too contaminated to be reused. So best way to use for single effect over multiple effect evaporator is Corrosive materials. 3.
