Abstract[English]
Provided herein are methods for the enzymatic production of alpha- cyclodextrin from sucrose. 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 alpha-cyclodextrin. The methods produce higher yields of alpha-cyclodextrin relative to beta-cyclodextrin, gamma-cyclodextrin, or both.[French]
L'invention concerne des procédés de production enzymatique d'alpha-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 alpha-cyclodextrine. Dans certains cas, les procédés produisent des rendements plus élevés d'alpha-cyclodextrine par rapport à la bêta-cyclodextrine, la gamma-cyclodextrine, ou les deux.
