ABSTRACT:
This invention is directed to a novel process in which raw sugarcane juice is first refined through a number of steps and then bioenzymatically converted into refined invert syrup or glucose-fructose concentrated solution using a reactor packed with immobilized invertase. The refining steps preferably include a first filtration (particle filtration or microfiltration) followed by a second filtration (microfiltration or ultrafiltration) and then at least one pass through a column packed with an anionic exchange resin. The refined sugarcane juice can be optionally concentrated and/or pasteurized before passing through a reactor packed with immobilized invertase to convert sucrose to glucose-fructose.
