摘要：

2-phenyl ethanol is a natural compound, which have many applications due to its nice fragrance, bacteriostatic and antifungal character. However, it is difficult to keep it stable and it is highly volatile. In this work, chitosan films with 2-phenyl ethanol were developed and inclusion complexes with cyclodextrins (CDs) were prepared in order to have a controlled release of 2-phenyl ethanol. beta-CD was selected to develop the inclusion complex since it showed higher retention yield (45%, molar basis) than alpha- or gamma-CDs. Chitosan films incorporated with beta-CD:2-phenyl ethanol were homogeneous, transparent and colorless, and showed high mechanical resistance. Furthermore, the release results of the films without the inclusion complex indicated that 2-phenyl ethanol was evaporated during the film preparation, and only an 8% of the total bioactive was retained in the film, while more than 90% of 2-phenyl ethanol was retained in the films with the inclusion complex.
