Embodiment Construction

[0012] The method is realized by the following specific process steps:

[0013] (1) Soaking syrup: Soak Jerusalem artichoke (Jerusalem japonicus) and cook to extract the active ingredients, then process the process of filtration, decolorization, separation, concentration and drying to make Jerusalem artichoke powder, and then the Jerusalem artichoke powder is hydrolyzed by endo-inulinase to obtain fructooligosaccharide syrup;

[0014] (2) Hydrogenation: Detected by high performance liquid chromatography, the content of kestose in the fructooligosaccharide syrup is 19.69%, the content of kestetose is 33.48%, the content of kestopentaose is 18.54%, glucose The content of fructooligosaccharides is 24.78%, the content of fructose is 2.17%, and the content of other miscellaneous sugars is 1.34%. Dilute the fructooligosaccharide solution with pure water to a refractive concentration of 40%, adjust the pH value to 7.8, and then add it to the high-pressure hydrogenation reactor Add t...

Abstract

The invention relates to a method for improving the quality of fructo-oligosaccharides, which is characterized in that the method adopts hydrogenation technology to hydrogenate a fructo-oligosaccharide liquid which is generated by conversion of jerusalem artichoke powder, converts glucose in the fructo-oligosaccharide liquid into D-sorbitol sorbitol and fructose into the D-sorbitol sorbitol and mannitol, and keeps 1-kestose, nystose and 1F-Fructofuranosyl nystose unchanged because the 1-kestose, the nystose and the 1F-Fructofuranosyl nystose do not have reductibility. The method comprises: firstly, syrup infusion; secondly, hydrogenation; thirdly, decolorization; fourthly, ion exchange; and fifthly, condensation. Therefore, the method can obtain fructo-oligosaccharide products with higherquality. The method converts saccharides in the fructo-oligosaccharides into functional sugar alcohol which is beneficial to human body, widens the application scope of the fructo-oligosaccharide products, and has the advantages of easy, simple and convenient technique, stable product quality, low production cost, high separation and extraction efficiency, favorability for improving the quality of the fructo-oligosaccharides and production, application and promotion of the products, and so on.

Description

technical field [0001] The invention belongs to the technical field of sugar industry and relates to a method for improving the quality of fructo-oligosaccharides. Background technique [0002] Fructose oligosaccharides, also known as fructo-oligosaccharides, are kestose, kestose and kestrose formed by combining 1-3 fructosyl groups with fructosyl groups in sucrose through β-2,1-glucosidic bonds. Mixture of sugar etc. In industrial production, Jerusalem artichoke (Jerusalem japonicus) is used as raw material, soaked and boiled to extract active ingredients, and then processed into Jerusalem artichoke powder through filtration, decolorization, separation, concentration, and drying. Fructose Syrup. [0003] In the current production, fructo-oligosaccharide products often contain more than 20% glucose and a small amount of fructose. The existence of these reducing sugars makes it unable to meet the requirements of making sugar-free food. In order to improve the quality of fr...
