Abstract
The compositions of the various organic and inorganic
species in cane molasses show wide variations. Centrifugation
can be used to remove suspended so!id particles. The bulk of
these are precipitated calcium compounds. Removal of
calcium by precipitation and subsequent centrifugation can be
enhanced by the addition of sulphuric acid. The effects of
dilution, temperature, and acid addition on the efficiency of
calcium removal by centrifugation are described. A relatively
simple procedure to determine the optimal molasses pretreatment
method for maximum calcium removal is presented.
