Method for refining a liquor, comprising an aqueous solution of a carbohydrate, said liquor being contacted with a non-liquid (solid or gelatinous) adsorbent which is fit or adapted to accumulate the relevant carbohydrate on its surface. The carbohydrate may be a saccharide, e.g. a di-, or an oligosaccharide, or a sweet tasting sugar derivative. Furthermore, said carbohydrate may be a mixture of (reduced) mono-, di-, and oligosaccharides. The adsorbent may be a organic polymer or an inorganic material which is capable of or functionalised to exhibit CH-À interactions and/or hydrogen bonding interactions to accumulate the carbohydrate on its surface. The adsorbent may be is a porous solid, a gel type material or a monolithic structure. To accumulate the carbohydrate, the liquor may be contacted with the adsorbent's surface at a first temperature, while, to collect the carbohydrate, the adsorbent's surface is washed out by a desorption liquid at a second temperature which is relatively high compared with the first temperature.
