Abstract

The invention relates to a method for purifying resistant dextrin by sequential simulated mobile chromatography. The method uses a preparation solution of resistant dextrin as a raw material, wherein the content of resistant dextrin is 40%, and the mass content of miscellaneous sugars is 40%. After pretreatment, the concentration of the resistant dextrin preparation solution is adjusted to 60%, and the eluent is deionized water; the pretreated resistant dextrin preparation solution is purified by sequential simulated mobile chromatography, the first stage: the system simultaneously enters the resistant dextrin preparation solution Dextrin preparation liquid, enter eluent, and discharge; second stage: the material does not enter and exit, and a large cycle is carried out, and the direction of liquid flow is from column 1 to column 6; third stage: only enter eluent for deionization Water, eluent deionized water into column 1, part of the resistant dextrin component from the outlet at the lower end of column 5; feed inlet, eluent inlet, first outlet, and second outlet Move to the next column sequentially along the direction of column 1 to column 6, and repeat the purification cycle until the purification is completed. The process of the invention has low operating cost and can be continuously produced.

Description

[0001] 1. Technical field: [0002] The invention relates to a sequential simulated mobile chromatography separation and purification technology in the field of food industry, in particular to a sequential simulated mobile chromatography purification method for resistant dextrin. [0003] 2. Background technology: [0004] Due to changes in social structure, eating habits and food composition have changed, and the intake of dietary fiber is also decreasing year by year. However, with the deepening understanding of the relationship between dietary fiber and human body functions, the importance of dietary fiber is also increasing. It has been recognized by the world, and the demand for it has also continued to increase. [0005] Resistant dextrin is a low-viscosity water-soluble dietary fiber, which has the characteristics of low sweetness, low calorie, heat resistance, acid resistance, and difficult fermentation. It can regulate human intestinal flora, improve blood sugar and fa...
