[ 1] als Modifikator zur Verbesserung der … Cyclodextrins are a family of cyclic oligosaccharides, consisting of a macrocyclic ring of glucose subunits joined by α-1,4 glycosidic bonds. Cyclodextrins are produced from starch by enzymatic conversion. They are used in food, pharmaceutical, drug delivery, and chemical industries, as well as agriculture and environmental engineering. Cyclodextrine werden biotechnologisch durch den enzymatischen Abbau von Stärke, etwa aus Mais oder Kartoffeln, hergestellt. Die hierfür eingesetzten Enzyme werden als Cyclodextrin-Glycosyltransferasen, kurz CGTasen bezeichnet. Diese sind in verschiedenen Bakterien und Archaeen zu finden, wobei industriell die aus dem Bacillus macerans isolierten CGTasen am bedeutsamsten sind. Bei der Einwirkung auf Stärke schneidet die CGTase aus der helikal gewu…

WebFeb 1, 2007 · Cyclodextrins were first described by Villiers in 1891. Schardinger laid the foundation of the cyclodextrin chemistry in 1903-1911 and identified both alpha- and beta-cyclodextrin. In the 1930s, Freudenberg identified gamma-cyclodextrin and suggested that larger cyclodextrins could exist. WebCyclodextrins (CD) are enzymatically modified starches with a wide range of applications in food, pharmaceutical and chemical industries, agriculture and environmental engineering. They are produced from starch via enzymatic conversion using cyclodextrin glycosyl transferases (CGTases) and partly alpha-amylases.
