Abstract[English]
Provided herein are methods for the enzymatic production of gamma-cyclodextrin from sucrose. In some cases, the methods involve contacting sucrose with one or more enzymes to convert sucrose to amylose, followed by contacting the amylose with one or more enzymes to convert the amylose to gamma-cyclodextrin. In some cases, the methods produce higher yields of gamma-cyclodextrin relative to alpha-cyclodextrin, beta-cyclodextrin, or both.[French]
L'invention concerne des procédés de production enzymatique de gamma-cyclodextrine à partir de saccharose. Dans certains cas, les procédés consistent à mettre en contact du saccharose avec une ou plusieurs enzymes pour convertir le saccharose en amylose, puis à mettre en contact l'amylose avec une ou plusieurs enzymes pour convertir l'amylose en gamma-cyclodextrine. Dans certains cas, les procédés produisent des rendements plus élevés de gamma-cyclodextrine par rapport à l'α-cyclodextrine, à la bêta-cyclodextrine, ou aux deux.
