In the present invention amorphous sugar is transformed to a mesomorphic product having polycrystallites therein by a completely anhydrous process rather than by hydrating and then dehydrating the sugar. The product of the present invention is unique in shape and size, and possesses a high degree of uniformity. The properties of the polycrystallite make it possible to replace some or all of the fat in comestibles such as frostings and fillings and to provide fondants of extraordinarily fine grain.Type: GrantFiled: August 12, 1997Date of Patent: October 17, 2000Assignee: Fuisz Technologies LtdInventors: Subraman R. Cherukuri, Jose F. Zamudio-Tena, Robert K. Yang, Andrea S. Blake, Paul M. Croushorn

Patent number: 6096136Abstract: Nanofiltration is used to decolorize sugar juice or syrup. The resulting permeate may be used directly to crystallize white sugar without an intermediate step of producing a raw sugar; even though the color of the permeate is substantially higher than the highest color that is acceptable in a conventionally decolorized syrup used to crystallize white sugar. Significant cost savings are thus achieved in producing white sugar.Type: GrantFiled: October 18, 1996Date of Patent: August 1, 2000Assignee: Board of Supervisors of Louisiana State University and Agricultural and Mechanical CollegeInventor: Michael Saska

Patent number: 5902408Abstract: The present invention is related to a process for refining raw sugar comprising the steps of: (a) dissolving either washed raw sugar or raw sugar directly to produce a melter liquor; (b) clarifying the melter liquor; (c) crystallising the melter liquor to produce a mixture of a very low colour intermediate sugar and a syrup; (d) separating the very low colour intermediate sugar from the syrup; (e) redissolving the separated very low colour intermediate sugar to produce a fine liquor; (f) filtering the fine liquor to remove any foreign particles which may have contaminated the sugar produced in step (d); and (g) crystallising refined sugar from the fine liquor. The invention is also related to a process for producing very low colour (VLC) intermediate sugar by the steps of (a) to (d) defined above.Type: GrantFiled: December 9, 1997Date of Patent: May 11, 1999Assignee: CSR LimitedInventors: Murray Richard Player, Peter James Field

Patent number: 5873943Abstract: To provide an economically advantageous process for manufacturing crystalline maltitol and crystalline mixture solid containing crystalline maltitol. The process of this invention uses the syrup having a maltose purity of 81 to 90% as the starting material. The syrup is hydrogenated under the existence of catalyst, and then subjected to a chromatographic separation by using cation-exchange resin, resulting in an aqueous solution of maltitol having a maltitol purity of 94 to 99.9%. The aqueous solution, is further crystallized in the presence of a seed crystal, subjected to a separation, cooled and kneaded so as to manufacture both crystalline maltitol and crystalline mixture solid containing crystalline maltitol at the same time.Type: GrantFiled: May 2, 1996Date of Patent: February 23, 1999Assignee: Towa Chemical Industry Co., Ltd.Inventors: Mitsuo Magara, Koichi Kataura, Yoshiaki Tateno, Yoshimasa Onuki, Yuji Osada, Fumito Yamazaki, Kazuaki Kato
