    摘要: 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 comprising or being a component of a lipase, esterase, amylase, .alpha.-galactosidase or protease preparation, the enzyme treatment being effected in an aqueous system. Sucralose can be obtained by using this method to obtain a sucrose 2,3,6,3',4'-penta ester which can then be chlorinated and de-esterfied. Some of the penta acetates, tetraacetates and mixed acetates/butyrates are new compounds.

    摘要: 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 particle size of at most 10 microns. A method of enhancing the thermal stability of crystalline sucralose comprises jet milling the sucralose to reduce the particle size, and render the size distribution such that the maximum size is no more than twice the mean.

    摘要: Sugar (sucrose or glucose) is crystallized by passing a hot supersaturated syrup to a continuous screw extruder such that progressive nucleation of the syrup is induced during a mean residence time of below 25 seconds and then discharging the nucleated syrup onto a surface, e.g. a conveyor belt, to crystallise without agitation.
