Abstract:
A method for producing tagatose comprises: a) performing epimerization of fructose using hexuronate C4-epimerase to obtain an epimerized product comprising tagatose; b) purifying the epimerized product; and c) crystallizing the purified epimerized product. The hexuronate C4-epimerase is an enzyme derived from Thermotoga maritima, Thermotoga neapolitana, Thermotoga thermarum or mutants thereof. The hexuronate C4-epimerase is produced from strains Escherichia coli, Corynebacterum glutamicum, Aspergillus oryzae, or Bacillus subtilis.
