METHOD FOR PREPARING TAGATOSE FROM RESIDUE AFTER EXTRACTING COFFEE

摘要

The present invention relates to a method for preparing tagatose from residue after extracting coffee, comprising: obtaining a hydrolysate by hydrolyzing residue after extracting coffee into acid; obtaining a hydrolysate refined by bleaching and ion-refining the obtained hydrolysate; and obtaining tagatose by isomerizing the refined hydrolysate to an arabinose isomerase.
