Abstract

The invention relates to a preparation method for palatinitol crystals. The method includes the following steps of firstly, concentrating a liquid palatinitol solution, and conducting heat preservation; secondly, cooling organic solvent, and making the temperature of the organic solvent smaller than or equal to 10 DEG C; thirdly, dropping palatinitol in the molten state in the organic solvent preprocessed in the second step, wherein palatinitol drops are condensed into granular solid when cooled; fourthly, collecting the palatinitol solid obtained in the third step, conducting drying through cold air, and obtaining the required palatinitol crystals. The palatinitol crystals generated according to the method are uniform and granular solid and have the advantages of being high in mobility, easy to smash and the like and are quite superior to powdery products generated according to an existing spray drying method and granular products generated according to an existing mixing granulation method. The method has the advantages of being easy to operate, small in device investment, small in occupied area, high in product yield, and the like.

Description

technical field [0001] The invention relates to a preparation method of isomalt crystals. Background technique [0002] Isomalt, also known as hydrogenated isomaltulose or palatinitol, is a mixture of two isomers, namely α-D-glucopyranosyl-1,6 -D-sorbitol (1,6-GPS) and α-D-glucopyranosyl-1,1-D-mannitol dihydrate (1,1-GPM dihydrate). Isomalt is about half the sweetness of sucrose, slightly hygroscopic, and has a melting point of 145-150°C; it is soluble in water, and its solubility in water is lower than that of sucrose at room temperature. [0003] Chinese patent CN101781341A discloses a process for producing isomalt crystals. The method mainly uses isomaltulose solution as a raw material, and reacts with hydrogen under the action of a nickel catalyst to generate isomaltulose solution. Then use cooling crystallization, simulated moving bed chromatography system SMB, negative pressure evaporation crystallization and other comprehensive processes to produce high-purity isoma...
