Embodiment 1

[0048] In order to verify the feasibility and economy of the method for chromatographic separation of maltitol of the present invention in the separation of maltitol, a small industrial chromatographic separation test was carried out in cooperation with Shandong Bailong Chuangyuan.

[0049] A method for chromatographically separating maltitol of the present invention, the liquid material to be separated is separated through a chromatographic separation system, so that the concentration of the maltitol component after separation is increased to 95%, and then directly concentrated for one crystallization to obtain crystalline maltitol product.

[0050] In the chromatographic separation system, the circular back pressure feeding system is adopted to realize smooth continuous feeding. The following is the discharging system, and the feeding and discharging are all switched by program control through pneumatic switch valves.

[0051] The process is simple and adopts automatic contr...

Abstract

The invention belongs to the technical field of maltitol separation, and particularly relates to a chromatographic separation method for maltitol. A liquid material needing to be separated is separated through a chromatographic separation system, so that the concentration of the separated maltitol component is increased to 95%, and then the maltitol component is directly concentrated and subjectedto primary crystallization to obtain a crystalline maltitol product; the total yield is ensured. According to the method, by adopting a chromatographic separation system, parameters in the separationprocess are optimized and selected, and the method which is used for obtaining maltitol and is convenient to operate, low in cost and high in product quality is obtained.

Description

technical field [0001] The invention belongs to the technical field of maltitol separation, in particular to a method for chromatographic separation of maltitol. Background technique [0002] Maltitol is a new type of functional sweetener, which has attracted widespread attention due to its low-calorie, non-carious, indigestible, and calcium absorption-promoting properties. Maltitol, also known as hydrogenated maltose, the chemical name is 4-O-α-D-glucosyl-D-glucitol, and the molecular formula is C 12 h 24 o 11 , the relative molecular mass is 344.31. Maltitol is white crystalline powder or colorless transparent neutral viscous liquid, easily soluble in water, insoluble in methanol and ethanol. Strong hygroscopicity, maltitol sweetness is 90% of sucrose, good flavor. The calorific value of maltitol is only 2.1 calories / g, which can inhibit the accumulation of excess body fat. Maltitol does not contain aldehyde groups, has no reducing effect, and has better heat resista...
