  • Process for the production of a colorless sugar syrup from cane molasses
    Patent number: 4046590
    Abstract: A process for producing a colorless low-ash, high-purity sugar syrup from cane molasses wherein centrifuged molasses is acidified and treated with an ion exclusion resin. The resin is then eluted with water, and fractions of similar compositions are combined for recycling. The process yields a product similar to refiner's syrup, which is readily further purified by carbon and ion exchange resins to provide a high-quality syrup.
