Abstract: Described herein is a method of adjusting the composition of a chromatography product to achieve a target enriched proportion of a desired component from an input feed having a lower proportion of the desired component using simulated moving bed (“SMB”) chromatography wherein the eluent for the SMB apparatus may comprise the very input feed being enriched. The method is exemplified by enriching a high fructose corn syrup from a 42% fructose syrup to a 55% fructose syrup without substantially reducing the dissolved solids concentration of the 55% syrup relative to the input 42% syrup. The 42% syrup is also used as the eluent for the SMB apparatus and may be reconstituted from the raffinate stream by passing the raffinate stream over a glucose isomerase column alone or in combination with a dextrose feed. The method reduces water usage and saves energy by minimizing the need for evaporation to obtain a 55% fructose syrup with a high dissolved solids content.
