摘要： A process and system for continuous crystallization of a compound using antisolvent addition in which a solution is prepared with an organic compound and a solvent. An antisolvent is added to the solution in a continuous plug flow system comprising at least one process module. The antisolvent can be added in multiple addition points such that the overall amount of antisolvent added to the continuous plug flow reactor remains fixed. The multiple addition point technique provides every process module with an equal volume of antisolvent. Finally, crystals are recovered from the slurry upon exiting the system. Preferably, the mean crystal size is less than 100 μm.

摘要： A method for the high-throughput non-photochemical laser induced nucleation of crystals from aged supersaturated solutions in which short high-intensity laser pulses are used to induce nucleation in an array or sequence aged supersaturated solutions. The laser reduces nucleation time and induces nucleation only in the area where the beam is focused or passes through, resulting in fewer nuclei than would be achieved by spontaneous nucleation. The high-throughput methodologies allow more crystals to grow in a given amount of time.

摘要： The invention provides methods of purifying rebaudioside A from a mixture comprising glycosides of the plant Stevia rebaudiana. The methods of the invention are useful for preparing highly pure rebaudioside A compositions from crude Stevia starting compositions that are typically considerably lower in rebaudioside A concentration. The highly pure rebaudioside A compositions are useful as non-caloric sweeteners in edible or chewable compositions such as food, beverages, medicine, candy, chewing gum, and the like.
