Embodiment 1

[0053] Example 1 Chromatographic separation 1

[0054] The trehalose enzymatic hydrolyzate prepared from starch or maltose is decolorized, ion-exchanged, and concentrated to obtain a refined enzymolyzate with a mass percentage concentration of 50-60wt%. The enzymolysis solution enters the first set of chromatographic separation system for separation. The chromatographic separation system uses sequential simulated moving bed chromatographic separation technology, which has the characteristics of high degree of automation, easy operation, high separation strength and high concentration of separated products.

[0055] According to the method of the present invention, the separation agent used in chromatographic separation 1 and chromatographic separation 2 is calcium-type cation separation resin or calcium-type cation molecular sieve, and is loaded into a sequential simulated moving bed chromatographic separation device. There are finished separating agents on the market with st...

Embodiment 2

[0058] Example 2 Hydrogenation

[0059] Maltose in the extract is reducing, while trehalose is a non-reducing sugar. Hydrogenate the mixed solution at 100-140°C, 4MPa-12MPa, in the presence of a nickel catalyst, the maltose is hydrogenated and reduced to maltitol, but the trehalose is not hydrogenated, so a hydrogenated mixed solution containing maltitol and trehalose is obtained. Both maltitol and trehalose are products with high added value.

Embodiment 3

[0060] Embodiment 3 Chromatographic separation 2

[0061] The hydrogenated mixed solution containing maltitol and trehalose is decolorized, ion-exchanged, and concentrated to a mass percentage concentration of 50-60 wt%. The peak times of maltitol and trehalose on the chromatogram are quite different, so they can be separated by chromatographic methods more easily. The hydrogenated liquid mixture enters the second chromatographic separation system for separation. The chromatographic separation system uses sequential simulated moving bed chromatographic separation technology. The separation agent used is calcium-type cation separation resin or calcium-type cation molecular sieve, which is installed in a sequential simulated moving bed chromatographic separation device. There are finished separating agents on the market with stable performance. The eluent used is purified water, namely deionized pure water or reverse osmosis pure water, which is economical and easy to obtain. ...

Abstract

The invention provides an efficient clean production process for mycose. According to the production process, a chromatographic separation technology is flexibly applied to industrial production of mycose. An enzymatic hydrolysis liquid of mycose is prepared by using maltose, is subjected to decoloring and ion-exchange refining processing, and then enters a chromatographic separation system for separation. A common calcium type separating agent used in industry in large scale is selected for separating glucose and disaccharides, wherein disaccharides mean maltose and mycose. The extraction liquid is abundant in maltose and mycose. Maltitol obtained through reduction of maltose and mycose are both products with extremely high added value. The mixed solution is hydrogenated at a high temperature under a high pressure, maltose is reduced into maltitol through hydrogenation, and mycose does not possess reductivity and is not hydrogenated, so that a hydrogenation mixed solution containing maltitol and mycose is obtained. The hydrogenation mixed solution is subjected to purification processing and then enters a second chromatographic separation system for separation, the extraction liquid have a high-content mycose material, and the extraction liquid is subjected to evaporation heat crystallization or cooling crystallization, so as to obtain crystallized mycose.

Description

technical field [0001] The invention relates to a technique for producing trehalose, belonging to the technical field of sugar alcohol production techniques. technical background [0002] Trehalose is a type of non-reducing disaccharide widely present in yeast, seaweed, mold, bacteria, insects and organisms. It is a stress metabolite that gives organisms the ability to resist harsh environments such as dryness, drought, and cold. . Because trehalose has unique physiological functions different from other carbohydrates, it has been widely used in the fields of food, cosmetics, medicine, and health products, as well as for the stabilization and preservation of various biologically active substances such as enzymes and vaccines. [0003] The content of trehalose in nature is very low, and it was mainly extracted from dry yeast in the past. Yeast grows in a harsh environment, and the yeast can accumulate a large amount of trehalose. Extracting trehalose from yeast is the earli...
