| 6943248 | Crystalline form of sucralose, and method for producing it A crystalline form of sucralose, and a method of making it. The method involves continuously crystallizing sucralose from an aqueous solution by a process providing continuous removal and recirculation of the vessel contents, and providing a long residence time for ... | 09/13/2005 |
| 6217664 | Process for treating a sucrose syrup The present invention provides a fractionation process for treating an aqueous sucrose syrup having, on a dry basis, an initial sucrose content of at least 30 w/w % comprising combining the syrup with a solvent selected from the group consisting of alkano... | 04/17/2001 |
| 5932720 | Solid sucralose The flowability of crystalline sucralose can be increased by treating the crystalline material in a fluidised bed at ambient temperature with additions of water, followed by a fluidised drying phase. Fluidisation by means of an upward current of air at 25... | 08/03/1999 |
| 5270460 | Sucrose 6,4'-dicarboxylic esters Sucrose or derivatives thereof such as esters are acylated at the 4'- and/or the 6- position by reaction with a donor acyl ester, e.g. a reactive ester of an alkanoic acid or benzoic acid, in the presence of lipase. Sucrose 6,4' so produced can be chlorin... | 12/14/1993 |
| 5141860 | Preparation of acylated sucrose derivatives Sucrose derivatives partially acylated in each ring can be obtained by treating a fully or partially acylated sucrose derivative with an enzyme having sucrose esterase activity capable of removing at least one acyl group from each ring, generally comprisi... | 08/25/1992 |
| 4918182 | Sweetener Crystalline sucralose having a mean particle size of at most 10 microns, the maximum particle size being no more than twice the mean, exhibits enhanced stability to heat. Preferably the sucralose has a mean particle size of at most 5 microns and a maximum... | 04/17/1990 |
| 4889928 | Sucrose alkyl 4,6-orthoacylates Sucrose 6-acylates, key intermediates in the preparation of sucralose, can be prepared by subjecting a sucrose alkyl 4,6-orthoacylate to mild aqueous acidic hydrolysis to provide a mixture of sucrose 4- and 6-acylates and then treating the mixture with a ... | 12/26/1989 |
