ABSTRACT:
A process for decolorizing an aqueous solution of methyl glucoside, the solution containing at least one color component and at least one sugar component, is disclosed. The process comprises the steps of providing the aqueous solution of MeG; adding to said solution an amount of yeast or other sugar-converting microorganism sufficient to reduce the level of said sugar component; preferably further adding to the solution an amount of activated carbon sufficient to assist the color component in the solution; and recovering the solution to yield a decolorized, low-sugar solution of MeG. Also disclosed is a process comprising the steps of providing a solution containing MeG and dextrose; and adding to the solution an amount of a sugar-converting microorganism sufficient to reduce the level of the dextrose in the solution. Decolorized MeG solutions prepared by the foregoing processes also are disclosed.
