Abstract
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 decolorization and ion-refining the obtained hydrolysate; and obtaining tagatose by isomerizing the refined hydrolysate to an arabinose isomerase.

1-16. (canceled)
A method for preparing tagatose from spent coffee grounds, comprising:
- hydrolyzing spent coffee grounds with an acid to obtain a hydrolysate,
- decolorization and ion refining the resulting hydrolysate to obtain a refined hydrolysate, and
- isomerizing the refined hydrolysate with an L-arabinose isomerase to obtain tagatose.
A method for preparing tagatose from spent coffee grounds, comprising:
- preparing galactose from spent coffee grounds, and isomerizing galactose using an L-arabinose isomerase to obtain tagatose.
