The popularity of plant bioactive ingredients in the food industry is increasing. However, these ingredients have some deficiencies. Cyclodextrins (CDs) have been extensively studied as excellent carriers for plant bioactive ingredients and can be added to film materials to create bioactive food packaging. This review summarizes the extraction methods of plant bioactive ingredients, the addition of CD inclusion compounds to thin-film materials, and their applications in food packaging. The release model and mechanism of active film materials based on various plant bioactive ingredients with CDs are also highlighted.
The popularity of plant bioactive ingredients has become increasingly apparent in the food industry. However, these plant bioactive ingredients have many deficiencies, including low water solubility, poor stability, and unacceptable odor. Cyclodextrins (CDs), as cyclic molecules, have been extensively studied as superb vehicles of plant bioactive ingredients. These CD inclusion compounds could be added into various film matrices to fabricate bioactive food packaging materials. Therefore, in the present review, we summarized the extraction methods of plant bioactive ingredients, the addition of these CD inclusion compounds into thin-film materials, and their applications in food packaging. Furthermore, the release model and mechanism of active film materials based on various plant bioactive ingredients with CDs were highlighted. Finally, the current challenges and new opportunities based on these film materials have been discussed.
