Production method for anhydro sugar alcohol having markedly reduced ion content and improved colour characteristics
The present invention relates to a production method for an anhydro sugar alcohol having a markedly reduced ion content and improved color characteristics, and, more specifically, relates to a method for producing an anhydrous sugar alcohol having a markedly reduced ion content, markedly lowered electrical conductivity and improved color characteristics, which is obtained by subjecting hydrogenated sugar (sugar alcohol) to a dehydration reaction and thereby converting same to an anhydrous sugar alcohol and then subjecting distilled water, which has been isolated through a distillation step, to a decolorizing process using activated carbon, and subsequently bringing the resulting decolorized substance into contact with an ion exchange resin.
