Problems solved by technology

[0004] At present, xylo-oligosaccharide products produced by various methods, especially liquid products, still have decolorization technical problems due to technical problems. The product quality standard sets the appearance as a yellow or light yellow transparent liquid, but the color is affected by storage time and temperature. As a result, liquid products need t

Embodiment 1

[0018] Get 0.90kg of xylo-oligosaccharide syrup (xylo-oligosaccharide accounts for 70% of the total sugar ratio) of 70.8% refraction that has been sold publicly by Shandong Longli Biotechnology Co., Ltd., add pure water to adjust the solid content to 16% 1. Add 57g of Raney nickel catalyst, stir evenly, then adjust the pH value to 7.2 with caustic soda NaOH, open the reaction kettle, pour the adjusted xylooligosaccharide solution into the kettle, close the lid of the kettle, and replace the inside of the kettle with nitrogen gas Air and pressure test, then add hydrogen, start heating, adjust the pressure to 12MPa, pay close attention to the pressure change during the whole hydrogenation reaction process, and replenish the pressure in time according to the progress of the reaction. When the temperature rises to 70°C, the reaction starts. When the temperature rises to 125°C, stop heating, start heat preservation and pressure holding, and start timing. The DE value is detected at ...

Embodiment 2

[0020]Get the xylo-oligosaccharide syrup (xylo-oligosaccharide accounts for 70% of total sugar ratio) 3.0kg that the publicly sold refraction that Shandong Longli Biotechnology Co., Ltd. produces is 70.5%, add pure water and solid content water is adjusted to 53 %, add 253g of Raney nickel catalyst, stir evenly, then adjust the pH value to 8.0 with caustic soda NaOH, open the reaction kettle, pour the adjusted xylooligosaccharide solution into the kettle, close the lid of the kettle, and replace the kettle with nitrogen gas first Inner air and pressure test, then add hydrogen, start heating, adjust the pressure to 11MPa, pay close attention to the change of pressure during the whole hydrogenation reaction process, and replenish the pressure in time according to the progress of the reaction, when the temperature rises to 70°C, the reaction starts , when the temperature rises to 110°C, stop heating, start heat preservation and pressure holding, and start timing. The DE value is d...

Embodiment 3

[0022] Get 2.5kg of xylo-oligosaccharide syrup (xylo-oligosaccharide accounts for 70% of the total sugar ratio) of 70.5% refraction that has been sold publicly by Shandong Longli Biotechnology Co., Ltd., add pure water to adjust the solids content to 45% %, add 123.5g of Raney nickel catalyst, stir evenly, then adjust the pH value to 7.9 with caustic soda NaOH, open the reaction kettle, pour the adjusted xylooligosaccharide solution into the kettle, close the lid of the kettle, and replace it with nitrogen gas first The air in the kettle is tested for pressure, then hydrogen is introduced, and heating is started, and the pressure is adjusted to 9MPa. During the whole hydrogenation reaction process, pay close attention to the pressure change. At the beginning, stop heating when the temperature rises to 100°C, start heat preservation and pressure holding, and start timing. The DE value is detected at 20 minutes to 0.36%; the DE value is detected to be 0.12% at 30 minutes; the DE ...

Abstract

The invention discloses a method for preparing functional oligomerization xylitol, which belongs to the technical field. The preparation method comprises that common oligomerization xylose is taken as a raw material; and under the action of a catalyst, by a hydrogenation reaction, the functional oligomerization xylitol is prepared. The method has the advantages of improving product physical-chemical property and guarantee period of the oligomerization xylose, modifying strengthened physiological function of a product structure functional group, and effectively improving poor conditions of the prior material oligomerization xylose, wherein the process equipment and technical line are relatively mature, and easy to operate; moreover, on the basis of keeping basic physiological properties of the prior oligomerization xylose, the prepared functional oligomerization xylitol has higher sugariness and more pure sweetness, and tastes soft, and the liquid product is transparent.

Description

technical field [0001] The invention relates to a preparation method of functional xylooligosaccharides, belonging to the technical field of biochemistry. Background technique [0002] Oligosaccharide, or oligosaccharide, is a high-efficiency bifidus factor and a dietary fiber. It is a linear or branched oligosaccharide formed by 2-10 monosaccharides connected by glycosidic bonds. Oligosaccharides have many excellent properties, physiological activities and health functions, and are widely used in health care products, medicine, food, agriculture and other fields. In foreign countries, there is a strong demand for functional oligosaccharide products integrating "nutrition and health care". The wide application and development of oligosaccharides plays an important role in improving human immunity, preventing and inhibiting hyperlipidemia, diabetes, obesity and related diseases, especially for the proliferation of bifidobacteria and optimizing the micro-ecological balance in...
