The present invention relates to a method of preparing an allulose with stability at high yield, by concentrating products obtained by separating a solution containing allulose of a functional sweetener with high purity, to reduce the content of impurities such as fructose and reducing sugars and increase the content of allulose.

The present invention relates to a polycarbonate resin composition having excellent heat resistance and fluidity, and a molded product including the same.

The present invention relates to a method for culturing a strain having high psicose conversion activity and a method for producing psicose comprising thereof, and by confirming the batch, fed-batch culture optimization by establishing the optimal C/N ratio and the metal ion requirement, it is possible to maintain the high psicose conversion activity and mass-produce psicose efficiently.

The present invention relates to a thermoplastic polyether ester elastomer (TPEE) having a hard segment and a soft segment and a method for preparing the same and, more specifically, to a thermoplastic polyether ester elastomer and a method for preparing the same, wherein a unit derived from an anhydrosugar alcohol derivative with improved reactivity derived from biomass is contained in the soft segment, and thus through the adjustment of the content of the anhydrosugar alcohol derivative, elastic characteristics and physical characteristics (for example, hardness, etc.), which are important characteristics of an elastomer, can be favorably maintained, the melting point variously required in the molding process of a final product can be easily controlled, a problem of depletion of, especially, petroleum resources as finite resources, can be solved, and environmental friendliness can be improved.
