Embodiment 1

[0029] Get the refined isomaltooligosaccharide syrup (DS40-50%), adjust the pH of the syrup with reagent grade sodium hydroxide to be 7.9, inject 2 / 3 volume of sugar solution in the reactor, remove the air 3 times with nitrogen, and then Exclude nitrogen with hydrogen to make the hydrogen concentration above 99%.

[0030] The solid content of the syrup is 42%, and the activated skeleton nickel catalyst is added according to 9% of the dry matter, the temperature is controlled at 136°C, the hydrogen pressure is 8.5MPa, the stirring is started, and the rotation speed is 220r / min, and hydrogen is continuously added to promote the hydrogenation reduction. After reacting for 2 hours, when the hydrogen gas was introduced and was no longer absorbed by the syrup, the reducing sugar content was measured by the 3.5-dinitrosalicylic acid colorimetric method. When the reducing sugar reached 0.2%, the reaction could be terminated, and the generated oligoiso Maltitol, after decolorization an...

Abstract

The scheme relates to a method for preparing reduced isomaltooligosaccharide, which belongs to the technical field of preparation of starch sugar derivatives. In the method, isomaltose hypgather is taken as a raw material, and hydrogen is added under high temperature and a high pressure so as to perform a hydrogenation reaction, so that the reduced isomaltooligosaccharide is obtained. The production method of the reduced isomaltooligosaccharide comprises the keys as follows: isomaltose hypgather is added with hydrogen under high temperature and high pressure, the temperature is controlled between 80 to 140 DEG C, and the pressure is controlled between 6 to 10Mpa. The reduced isomaltooligosaccharide that is prepared by adopting the method achieves favorable heat resistance and stability to acid and alkali; a maillard reaction is avoided; and meanwhile, exceptional physiological performance characteristics of isomaltose hypgather can be kept.

Description

technical field [0001] The invention belongs to the technical field of preparation of starch sugar derivatives, and in particular relates to a preparation method of oligomeric isomaltitol. Background technique [0002] Isomaltooligosaccharide is made from starch through enzymatic hydrolysis and glycosyltransfer. It is also called branched oligosaccharide, which is formed by linking 2-10 glucose units. In addition to α-1,4 glycosidic bonds, there are also α-1,6 glycosidic bonds between each glucose. The sugar mainly contains isomaltose, isomaltotriose, panose, isomaltotetraose and other main components. Isomaltooligosaccharide is known as "bifidus factor" because it can improve constipation, reduce serum total cholesterol and low-density lipoprotein cholesterol, reduce physiological energy, and increase the number of bifidobacteria in the intestinal tract. One of the most popular functional oligosaccharides. [0003] Isomaltooligosaccharide has many excellent properties an...
