    摘要： A process for preparing an aqueous solution of a methylcellulose having 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 wherein 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, comprises the step of mixing the methylcellulose with an aqueous liquid at a temperature of not higher than 10° C. at a shear rate of at least 1000 s−1.

    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.
