Abstract:
An artificial sweetener composition contains sucralose and optionally a bulking agent such as maltodextrin. The composition is in the form of granules having a size between 30 and 2000 µm and containing between 0.5 and 1.5 wt% moisture. Any process can be used for making the compositions, with one especially applicable one involving pressing a powdered feed containing the raw materials between rolls to form a densified mass. The densified mass is then broken down in size and optionally fractionated by particle size.
Abstract:
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 sucralose in the system. The crystals thus formed are of a relatively low length/diameter ratio, have an unsymmetrical shape, and exhibit good stability. The larger crystals in particular are tapered as compared to the rod-like larger crystals in prior art product.
Abstract:
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 30w/w% comprising combining the syrup with a solvent selected from the group consisting of alkanols, ketones, and esters having 3 to 8 carbon atoms and mixtures thereof to form a system having at least two liquid phases in contact with a sucrose-containing solid phase and separating the phases, whereby there are obtained at least two products from the liquid phases, a first of which is characterised by a sucrose content, on a dry basis, greater than the initial content and a second of which is characterised by a sucrose content, on a dry basis, less than the initial content, in addition to a product obtained from the sucrose-containing solid phase.
Abstract:
A method for the preparation of a sucrose-6-ester is disclosed. In a first step of the method, sucrose in a polar aprotic solvent is reacted with an organotin-based acylation promoter. The water of reaction is removed at a temperature that does not exceed about 800C. In one aspect, the water is removed by distillation of part of the polar aprotic solvent at reduced pressure. In a second step, a carboxylic acid anhydride is added. In one aspect, the resulting reaction mixture is maintained at a temperature of 1O0C or less for a period of time sufficient to produce a sucrose-6-ester. The sucrose-6-ester can be converted to sucralose.
Abstract:
The present invention describes a polyhydroxycarboxylic acid having bimodal or multimodal molar mass distribution, a process for the preparation thereof, the use of an aromatic diol having a single benzene ring for the preparation of polyhydroxycarboxylic acid, in particular polyhydroxycarboxylic acid having bimodal or multimodal molar mass distribution, as well as a method of preparing injection- molded goods or blown film, polymer blends, composite materials or nanocomposite materials using said polyhydroxycarboxylic acid.
Abstract:
Polylactic acid blends having a relatively high heat distortion temperature can be prepared by simple blending of PLA polymers of opposite stereoforms, followed by processing, e.g. by injection moulding, under specific conditions of temperature and pressure, so as to produce a blend which, on differential scanning calorimetry, exhibits two peaks within the melting range of the stereocomplex. Moreover, by careful selection of these conditions of temperature and pressure, it is possible to use PLA polymers of significantly higher molecular weights than previously thought possible.
Abstract:
Synergy is obtained by combining sucralose and a saccharide sweetener selected from fructose, glucose, maltose and gluco-oligosaccharides, and mixtures thereof, and sugar alcohols.
Abstract:
The incorporation of units derived from isosorbide and from a polycarboxylic acid or anhydride thereof in a lactic acid polymer can result in a polymer having a higher glass transition temperature than would otherwise be achieved.
Abstract:
There is described a granulated sugar product comprising a core material substantially of a granulated first sugar and a surface material comprising a second sugar and a binder, wherein the surface material is less dense than the first sugar material. The product may comprise a high intensity sweetener.
Abstract:
A blend of a multiply branched lactic acid polymer of one steric configuration with a linear lactic acid polymer of the opposite steric configuration has different and more useful properties than either component alone.
