A process for the separation of a monosaccharide from an aqueous solution comprising the monosaccharide, in particular a hydrolysate of a polysaccharide containing biomass, characterized in that a) the solution comprises one or more salts or mineral acids, b) the solution is contacted with a zeolite adsorbent preferably of BEA zeotype for adsorbing the monosaccharide on the zeolite, c) the zeolite with the adsorbed monosaccharide is separated from the solution, d) the monosaccharide is separated from the zeolite absorbent. The process in a chromatographic process, in particular SMB, produces relatively highly concentrated and pure monosaccharide solution in water.

The present document describes a system and a process for the extraction of several products from apple peel. There are several unit operations involved including an ultrafiltration unit, concentration unit, and a three stage counter current separator centrifuge wherein water is used as the solvent. The final products that are extracted from apple peel include pectin, syrup, fibers, as well as soluble and dried retentate fractions.

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.

The present invention describes a process for a controlled conversion of a biomass feedstock, wherein the process comprises the steps of: loading the biomass feedstock to at least one reactor; liquefaction of the biomass feedstock into a monomer and/or oligomer sugar mixture in said reactor by treatment in hot compressed liquid water (HCW) at sub- and/or super-critical condition; and removal of the monomer and/or oligomer sugar mixture, being the product molecules, to avoid continued detrimental decomposition.
