METHOD FOR PRODUCING GALACTOSE CONSTITUTING A RAW MATERIAL FOR PRODUCING TAGATOSE FROM WHEY PERMEATE LIQUID OR WHEY PERMEATE POWDER

摘要

The present invention relates to a method for producing D-galactose from a dissolved solution of dried whey permeate or a liquid whey permeate, comprising: removing non-sugar insoluble materials from the dissolved solution of dried whey permeate or the liquid whey permeate; removing protein from the dissolved solution of dried whey permeate or the liquid whey permeate from which non-sugar solid precipitates are removed; and removing ash, salts or both from the dissolved solution of dried whey permeate or the liquid whey permeate from which the proteins are removed. Further, the present invention relates to a method for producing D-tagatose, comprising isomerizing D-galactose produced by the method of the present invention to obtain D-tagatose.
