Abstract
The deposition of calcium salts, including calcium carbonate and calcium oxalate and the formation of foam, during the evaporation of sugar streams can be prevented or restricted by ding 0.1-200 ppm of a carboxyalkylfructan that contains 0.5-3 carboxyl groups per monosaccharide unit, 0.4-2.5 of which carboxyl groups are in the form of carboxyalkyl groups, to the sugar streams. The carboxyalkyl groups are, in particular, carboxymethyl groups. The other carboxyl groups can be carboxyl groups obtained by oxidation.
