Embodiment 1

[0028] The method for purifying isomalt-oligosaccharide by sequential simulated mobile chromatography of the present invention uses sequential simulated mobile chromatographic equipment for purification. The sequential simulated mobile chromatographic equipment used in the present invention consists of 6 chromatographic columns (diameter 35mm, length 1000mm) , Each chromatographic column is 1L, a total of 6L, through the solenoid valve to control the feed and discharge. It is achieved through the following steps:

[0029] A) Blending of feed syrup: blend the isomalt oligosaccharide syrup after desalination and decolorization to a concentration of 60%;

[0030] B) Filtration: filter the syrup solution obtained in step A) with a micron filter to obtain a clear liquid without visible impurities;

[0031] C) Sequential simulated mobile chromatography purification: the syrup obtained above is purified by sequential simulated mobile chromatography equipment. The simulated mobile chromato...

Description

Technical field [0001] The present invention belongs to the field of food industry, and specifically relates to a sequential simulated moving chromatography separation and purification technology, in particular to a sequential simulated moving chromatography purification technology for isomalto-oligosaccharides. Background technique [0002] Isomaltooligosaccharides are oligosaccharides in which 2-8 glucose molecules are connected by α-1,6 glycosidic bonds. Under normal circumstances, isomalt oligosaccharides are not fermented by yeast, and can effectively promote the growth and reproduction of the beneficial bacteria Bifidobacterium in the human body, so it is also called "Bifidobacterium growth promoting factor". Bifidobacterium has many health functions. , And the isomalt oligosaccharide as a bifidobacterium promoting factor has naturally attracted people's attention. At the same time, isomalto-oligosaccharides have excellent processing characteristics. They have no special r...
