Abstract

The present invention provides a method for preparing allulose crystals, comprising the steps of: (a) adding allulose seed crystals to an allulose-containing mother liquor and performing a primary crystallization reaction while a reduced pressure condition of 10-100 mb is maintained and under a temperature gradient condition in which the temperature of the allulose-containing mother liquor is gradually lowered; and (b) releasing the reduced pressure condition when the allulose crystal precipitation rate of the primary crystallization reaction has reached 12% or more, and performing a secondary crystallization reaction while the supersaturated state of the metastable zone is maintained and under a temperature gradient condition in which the temperature of a D-allulose-containing mother liquor is gradually lowered. Allulose crystal particles obtained using the method for preparing allulose crystals, of the present invention, have a large average particle size, are inhibited from caking even if stored for a long time and have low hygroscopicity and excellent flowability. In addition, when the method for preparing allulose crystals, of the present invention, is used, allulose crystallization yield can be improved.

Abstract

One embodiment of the present invention provides a method for purifying an allulose-containing solution, the method comprising a step of obtaining an ion-purified allulose-containing solution by passing an allulose-containing solution through an ion exchange resin column filled with a mixed-phase ion exchange resin. In the method for purifying an allulose-containing solution according to an embodiment of the present invention, the mixed-phase ion exchange resin is a mixture of a strongly acidic cation exchange resin and a weakly basic anion exchange resin, the weakly basic anion exchange resin constituting the mixed-phase ion exchange resin having an exchange capacity fraction of quaternary ammonium of 0-10%. Using the method for purifying an allulose-containing solution according to the present invention not only enables the electrical conductivity of the allulose-containing solution to be lowered to an acceptable level, but also minimizes the loss of allulose because the conversion of allulose into fructose or other materials due to a functional group of the ion exchange resin can be suppressed. Therefore, the purification method for purifying an allulose-containing solution according to an embodiment of the present invention is suitable for the mass production of high-quality allulose.

Abstract

The present invention relates to a novel variant of threonine ammonia-lyase and a method for producing 5'-inosinic acid using same, the threonine ammonia-lyase variant having altered protein activity due to substitution of one or more amino acids in the amino acid sequence constituting threonine ammonia-lyase, thereby allowing recombinant microorganisms comprising the variant to efficiently produce 5'-inosinic acid.

Abstract

The present invention relates to a novel ABC transporter permease variant and a method for producing 5'-inosinic acid using same. The ABC transporter permease variant has modified protein activity due to the substitution of one or more amino acids in the amino acid sequence constituting an ABC transporter permease, and thus recombinant microorganisms comprising same can efficiently produce 5'-inosinic acid.
