Problems solved by technology

The products produced by this process have shortcomings such as low purity and poor fluidity of powder products.
This method is complex in process, large in equipment footprint, and high in investment. A spray drying tower requires tens of millions of RMB in equipment investment alone.

Abstract

The invention discloses a method for producing isomaltulose alcohol crystals. The method takes isomaltulose alcohol solution as raw material, utilizes the characteristic of the solubility difference of GPM and GPS serving as two isomers in isomaltulose alcohol and adopts a negative-pressure evaporation crystallization technique to produce isomaltulose alcohol crystals in a required molar ratio, as well as isomaltulose alcohol of which the total content is more than or equal to 98.5 percent, wherein GPM is high-purity isomaltulose alcohol crystals of which the content is above 96 percent or the isomaltulose alcohol of which the total content is more than or equal to 98.5 percent, and GPS is the high-purity isomaltulose alcohol crystals of which the content is above 96 percent.

Description

【Technical field】 [0001] The invention relates to the production field of functional sugar alcohols of food additives, in particular to a method for producing isomalt crystals. 【Background technique】 [0002] Isomalt, alias hydrogenation reaction palatinose (hydrogenation reaction isomaltulose), also known as isomalt or isomaltulose alcohol, it is a mixture of two isomers , respectively 1-O-α-D-glucopyranosyl-D-mannitol dihydrate (1,1-GPM dihydrate) and 6-O-α-D-glucopyranosyl- Sorbitol (1,6-GPS). [0003] The molar ratio of GPM and GPS of the existing commercial isomalt is mostly 1:1 or 1:1.3. Due to the huge difference in the solubility of GPM and GPS, there is currently no other ratio of isomalt for sale. There is no crystalline isomalt crystal of this molar ratio for sale yet, and the crystalline isomalt product has good fluidity and high purity. [0004] Most of the isomalt produced in the prior art is a powder product produced by spray drying and a granular product p...
