Beschreibung
Zusammenfassung:	The invention relates to a process for removing beta -cyclodextrin from egg yolk or egg yolk plasma using an alpha -amylase. This process is characterized in that the egg yolk or egg yolk plasma is treated with a maltogenic alpha -amylase originating from Bacillus stearothermophilus. The beta -cyclodextrin was incorporated into the egg yolk during a cholesterol extraction step. The invention further relates to egg yolk or egg yolk plasma obtained by the use of this process. L'invention concerne un procédé pour éliminer les beta-cyclodextrines du jaune d'oeuf ou du plasma de jaunes d'oeuf en utilisant une alpha-amylase. Ce procédé est caractérisé en ce que le jaune d'oeuf ou le plasma de jaune d'oeuf est traité avec une alpha-amylase maltogène provenant de Bacillus stearothermophilus. La beta-cyclodextrine a été incorporée dans le jaune d'oeuf durant l'étape d'extraction du cholestérol. L'invention concerne en outre les jaunes d'oeuf ou le plasma de jaunes d'oeuf obtenus par l'utilisation de ce procédé.
