PROCESS FOR CONTROLLED DEGRADATION IN CONCENTRATED SOLUTION OF LIQUID GLUCOSE SYRUPS - PRODUCT THUS OBTAINED AND ITS USE AS AN ADDITIVE FOR MORTARS AND CONCRETES

摘要

A process for the controlled degradation of liquid glucose syrups in concentrated solution snd in homogeneous phase wherein the reducing groups of glucose, maltose and maltodextrin are converted into the salts of the corresponding aldonic acids and/or into the salts of lower carboxylic acids (C1-C4) without substantially changing the polysaccharide components (degree of polymerization > 3) of maltodextrin, or with only partial depolymerization of the polysaccharide components, by using simple oxidants such as hypohalogenites or ferricyanides, or aqueous alyaline solutions. The conversion of the reducing sugars is equal to or greater than 95% and a very high reproductibility of the desired results is obtained. The invention also concerns the product obtained by the process and its use as an additive to cement mortars and concretes The present invention concerns a process for the controlled degradation of liquid glucose syrups in concentrated solution. More particularly, the present invention concerns a process for the controllod degradation of liquid glucose syrups in concentrated solution by elminating the reducing groups in the mono-, diand oligosaccharides.
