Abstract

The invention provides a method for efficiently preparing stachyose from stachys sieboldii. The method is characterized by comprising the following steps: taking Chinese traditional vegetable stachys sieboldii as a raw material; extracting the stachyose by adopting a pure water homogenate method; and spraying and drying after the processes of filtering a homogenate by a cloth bag; decolorizing the filtered homogenate with macroporous resin, performing ultrafiltration purification and reverse osmosis concentration, and the like, wherein a reverse osmosis permeate liquid is used as water for the homogenate and the resin decolonization elution in the production and the like, so not only resources can be used fully to meet the requirement on production water supply, but also the influence on the purity of the stachyose in the whole production system, caused by pollutants such as saline matters and the like in a natural water source, can be reduced to further improve the purity and the quality of the stachyose. By using the method of the invention, the extraction rate of the stachyose prepared can reach 75 and 85 percent, the purity of the stachyose in a product reaches over 90 percent, and the total recovery rate of the stachyose in the whole process reaches over 60 percent. The method combines a traditional extraction method and a modern separation method, has a simple process and a large handling capacity, is suitable for industrial production, and simultaneously has high product purity, saves resources and the production cost, and has good economic benefits and ecological benefits.

Description

technical field [0001] The invention relates to a high-efficiency preparation technology of functional oligosaccharides, in particular to the technical field of extracting and purifying food functional factors from traditional Chinese plants. Background technique [0002] Stachyose is a naturally occurring tetrasaccharide, belonging to the raffinose genus galactoside non-reducing functional oligosaccharides. It is composed of one molecule of glucose, one molecule of fructose, and two molecules of galactose. The structural formula is Fructose-glucose-galactose-galactose, molecular formula C 24 h 42 o 2 , the molecular weight is 666.59. Since the glucose group in the molecule and the two galactoses are connected by -D-galactosidic bonds, and the human body lacks α-D-galactosidase, stachyose cannot be digested and absorbed by the human body, and only intestinal A few beneficial bacteria such as Bifidobacterium and Lactobacillus acidophilus in the tract have an enzyme system...
