PROCESS FOR PREPARING AN AQUEOUS SOLUTION OF SACCHARIDES AND METHYLCELLULOSE

摘要

An aqueous solution comprising (a) one or more mono-, di- and/or oligosaccharides and (b) a methylcellulose, wherein the methylcellulose has anhydroglucose units joined by 1-4 linkages wherein hydroxy groups of anhydroglucose units are substituted with methyl groups such that s23/s26 is 0.36 or less, is produced by i) mixing the methylcellulose with an aqueous liquid comprising one or more mono-, di- and/or oligosaccharides at a shear rate of at least 1000 s−1 or ii) mixing one or more mono-, di- and/or oligosaccharides with the methylcellulose and/or an aqueous liquid before, simultaneously with or after mixing the methylcellulose with the aqueous liquid at a shear rate of at least 1000 s−1.

1. A process for preparing an aqueous solution comprising
(a) one or more mono-, di- and/or oligosaccharides and (b) a methylcellulose, wherein the methylcellulose has anhydroglucose units joined by 1-4 linkages wherein hydroxy groups of anhydroglucose units are substituted with methyl groups such that s23/s26 is 0.36 or less,
wherein s23 is the molar fraction of anhydroglucose units wherein only the two hydroxy groups in the 2- and 3-positions of the anhydroglucose unit are substituted with methyl groups and s26 is the molar fraction of anhydroglucose units wherein only the two hydroxy groups in the 2- and 6-positions of the anhydroglucose unit are substituted with methyl groups,wherein i) the methylcellulose is mixed with an aqueous liquid comprising one or more mono-, di- and/or oligosaccharides at a shear rate of at least 1000 s−1 orwherein ii) one or more mono-, di- and/or oligosaccharides are mixed with the methylcellulose and/or an aqueous liquid before, simultaneously with or after mixing the methylcellulose with the aqueous liquid at a shear rate of at least 1000 s−1.
