Embodiment 1

[0017] Ordinary maltotriose crude liquid, the content of each component is about 70% maltotriose, about 22% for glucose and maltose, DP 4 -DP 8 about 8%.

[0018] Take the refined maltotriose, adjust the mass percentage of the syrup to 56% with secondary reverse osmosis water, heat up to 60°C, use calcium-type cationic resin as the separation resin, and secondary reverse osmosis water as the eluent, pass through the column, Purified maltotriose was obtained. The purified maltotriose, detected by high performance liquid chromatography, its composition is glucose 0%, maltose 0.2%, maltotriose 91.8%, DP 4 -DP 8 8%.

[0019] Adjust the mass percentage of the purified maltotriose to 40% with two-stage reverse osmosis water, adjust the pH to 8.0 with reagent grade sodium hydroxide, inject 2 / 3 volume of sugar solution into the reaction kettle, and use nitrogen to remove the air 3 times, and then use hydrogen to exclude nitrogen, so that the hydrogen concentration can reach more...

Abstract

The invention provides a preparation method of high-purity maltotriose alcohol. The preparation method comprises the following steps of: (a) chromatographing and purifying: separating maltotriose from maltotriose and maltose by utilizing the chromatography technology to obtain maltotriose liquid with the component being more than 90%; (b) hydrogenating: carrying out hydrogenating reaction on the purified maltotriose to prepare the high-purity maltotriose alcohol by taking skeletal nickel as a catalyst under the conditions of the temperature being 80-130 DEG C and the pressure being 8-12Mpa; and (c) refining: carrying out activated carbon decoloration filtering, ion exchange desalination and vacuum concentration on the obtained high-purity maltotriose alcohol liquid to obtain a high-purity maltotriose alcohol product. Compared with the common sugar alcohol, the high-purity maltotriose alcohol prepared by the invention has the characteristics of high-purity single sugar alcohol, less micromolecule sugar alcohol, good hygroscopicity and moisturizing properties, low sweetness, good heat resistance and acid resistance, and the like.

Description

technical field [0001] The invention belongs to the technical field of starch sugar product preparation, and in particular relates to a preparation method of high-purity maltotriitol. Background technique [0002] The production of maltotriose alcohol is based on starch as raw material. After enzymatic saccharification and liquefaction to obtain maltotriose syrup with a maltotriose content of about 60%-70%, it undergoes hydrogenation reaction to generate maltotriose alcohol liquid. Its content is a mixture of various molecular alcohols, and the content of maltotriitol is about 60%-70%. [0003] High-purity maltotriitol is slightly lower than sucrose, and has mild sweetness and no off-flavor. Maltotriitol has significant hygroscopicity, it is difficult to be used by mold, yeast and lactic acid bacteria in animals, and it can prevent dental caries. It does not affect the rise of blood sugar and insulin levels, and it can be eaten by diabetics. Maltotriol can also inhibit th...
