ABSTRACT:
Free flowing, substantially pure, non-hygroscopic crystalline .beta.-L-gulopyranose is disclosed. This crystalline form of L-gulose is characterized by a sharp melting point of 130.degree.-132.degree. C., a specific optical rotation of +40.degree., characteristic mutarotation, a characteristic X-ray powder diffraction pattern, and a characteristic infrared spectrum. A method for preparation of crystalline .beta.-L-gulopyranose from L-gulose syrup is also disclosed. This method involves dilution of the L-gulose syrup, followed by initiation of crystallization, and isolation of .beta.-L-gulopyranose crystals. Crystalline .beta.-L-gulopyranose may be used as an alternative non-caloric or reduced caloric sweetener which substitutes for sucrose or dextrose in commercial dry prepared mixes for making beverages, cakes, puddings, breads, and the like. In addition, crystalline .beta.-L-gulopyranose may be used in applications in which the introduction of water is undesirable, such as jellies, icings, frostings and confections.
