摘要： The present invention is a method of improving the quality of taste of a sweetener such as stevioside comprising the steps of (a) providing a predetermined aqueous solution of Stevioside; (b) adding a predetermined substrate with a predetermined dextrose equivalent (D.E.) (c) mixing the aqueous solution of stevioside and substrate; (d) adding a predetermined transferase in a predetermined quantity to form a reacting solution; and (e) allowing the reacting solution to react for a predetermined reaction time under a predetermined controlled temperature to form a resulting product. Taking consideration of the production cost and percentage yield of the product, a predetermined set of reaction conditions are selected such that the percentage yield of 60-86% is achieved and the qualities of the taste of the sweentener such as the quality of sweetness, the pleasantness, the after-taste, the similarity to sucrose are improved.

摘要： The invention relates to a method of crystallizing maltitol from a maltitol solution by supersaturating the solution in respect of maltitol and crystallizing the maltitol from the solution. In the process of the invention, the maltitol-containing solution is brought to a supersaturated state, and the solution is subjected to evaporation, until a crystallization mass is obtained which has a crystal yield of 1 to 80% on maltitol, and a dry solids content of over 50%. After bringing the solution to a supersaturated state, the solution is preferably seeded by adding maltitol seed crystals. In one embodiment of the invention, additional feed liquid is added during the crystallization by evaporation.
摘要翻译：本发明涉及一种通过使麦芽糖醇相对于麦芽糖醇溶液过饱和并从溶液中结晶出麦芽糖醇而从麦芽糖醇溶液中结晶麦芽糖醇的方法。在本发明的方法中，使含麦芽糖醇的溶液达到过饱和状态，使溶液进行蒸发，直到得到在麦芽糖醇上具有1至80％的结晶产率的结晶物质，并且将干燥固体内容超过50％。将溶液置于过饱和状态后，优选通过加入麦芽糖醇晶种来接种溶液。在本发明的一个实施方案中，通过蒸发在结晶过程中加入另外的进料液。

摘要： Dextrins are prepared by hydrolyzing starch with an enzyme that consists essentially of a beta-amylase enzyme. The product prepared thereby will include a dextrin, such as beta-limit dextrin. Upon ultrafiltration of this product, a dextrin-rich fraction may be recovered. If desired, the dextrin-rich fraction may be further purified via diafiltration. Retrograded amylose may be separated from the product of enzymatic hydrolysis.
