Latest Patents

Jung holds a patent for an "Allulose epimerase variant with excellent thermal stability, preparation method therefor, and preparation method for allulose using same." This invention presents a novel allulose epimerase variant where an amino acid residue in the wild-type D-allulose 3-epimerase is substituted with another amino acid. The variant demonstrates a higher conversion activity of fructose to allulose compared to the wild-type enzyme, especially under high-temperature conditions of 60° C. or higher. This innovation is crucial for preventing contamination during industrial-scale enzymatic conversion reactions, thereby shortening production time and reducing costs.
