ABSTRACT:
A process for removing color, turbidity, flavor, and odor from impure, high Brix, sugar syrup involves entrapping the sugar impurities in an insoluble, primary calcium phosphate or aluminum hydroxide floc at about neutral pH, dividing the sugar syrup into a small portion and a large portion, aerating the small portion of the syrup at a specific Brix, recombining the small portion and the large portion, adding a polyelectrolyte to convert the primary floc into a secondary floc to which the air bubbles easily adhere and to cause flotation of said secondary floc, thus forming a scum mat at the top of the vessel. The purified sugar syrup is then filtered with or without activated carbon and small amounts of a filter aid to produce a sugar syrup with substantially reduced color, turbidity, flavor, and odor. The sugar in the scum is recovered by mixing it with water and allowing a second flotation to take place without any further aeration or chemicals addition.
