A process is provided for treating polysaccharides, such as starch maltodextrin and dextrin, with activated carbon, which comprises the steps of: a) dispersing the polysaccharide in an aqueous medium at up to 40% solids; b) passing the dispersed starch or dextrin through at least one column packed with pre-washed, granular, activated carbon at a flow rate of 0.1 to 20.0 bed volumes/hour which column has been loaded with wetted carbon granules, back-washed and pre-heated; and c) recovering the polysaccharide dispersion in a form which is substantially free of carbon fines. A starch, maltodextrin or dextrin prepared by this process is characterized by bland, non-objectionable color, odor and flavor and is substantially free of off-flavors. |
