Abstract

The invention discloses a preparation method of maltooligosaccharide glucoside. The preparation method comprises the following steps: weighing 300-400 parts of barley, adding 150-200 parts of phosphate buffer solution, adding the mixture into a stirring reaction kettle, and performing mechanical stirring for 15 hours; enabling the prepared glucoside D mixed solution added with the catalyst to be subjected to centrifugal operation, dissolving precipitates in distilled water and numbered as glucoside E, taking the glucoside E mixed solution, when the volume of the glucoside liquid in a dialysis bag is 1 / 4 of the original volume, finally obtaining maltooligosaccharide glucoside, and storing the prepared maltooligosaccharide glucoside, so the whole process is ended; wherein 2-ethylhexanol and a tribasic acid catalyst are added when the glucoside is prepared, and the 2-ethylhexanol and the tribasic acid catalyst are fully mixed with a mixed solution with the saturation degree of 80%; the reaction speed can be increased, the glucoside precipitation rate is increased, the subsequent production speed is increased, the labor burden is relieved for factory production, the yield is increased, and more economic benefits are brought to manufacturers.
