Sorption is the generic term used when adsorption and absorption processes cannot be
distinguished experimentally.
Sucrose % cane is the sucrose of formula C 12 H 22 O 11 in the absolute juice of the cane
expressed as a percentage.
Suspended solids are the dry solids in juice or other products removable by
physical means such as decantation, filtration or centrifugation.
Syrup is the concentrated sugar solution leaving the evaporators.
Trash (see extraneous matter).
Water activity a w of a substrate is defined as the ratio of the equilibrium vapour pressure of
water (p′) in the substrate to the vapour pressure of pure water (p o ) at the same
temperature, i.e.

Undetermined loss is the unaccounted sucrose loss when sucrose is extracted from cane
after taking into account the sucrose losses in bagasse, in filter cake and in molasses.
