Abstract

The work aims to systematically review the inclusion mechanism and preparation methods of β-CD plant essential oil microcapsules, as well as their application efficacy in active packaging and elucidate the mechanism by which they enhance the stability and controlled release performance of essential oils, thereby providing a theoretical basis for the development of natural active packaging materials. Through literature review and comprehensive analysis, the host-guest inclusion mechanism of β-CD and plant essential oils was summarized, the preparation techniques of both single β-CD wall material and composite wall material microcapsules were consolidated, their differences in structural characteristics, oil loading capacity, stability, and release behavior were compared, and their application modes and preservation effects in food active packaging systems were evaluated. β-CD could effectively encapsulate hydrophobic active components of plant essential oils, significantly improving their thermal stability, antioxidant activity, and processing adaptability. The composite wall material system outperformed the single β-CD system in terms of encapsulation efficiency, sustained release performance, and structural controllability. β-CD essential oil microcapsules demonstrated good application potential in inhibiting microbial growth, delaying food quality deterioration, and extending shelf life. β-CD plant essential oil microcapsules represent an important technological approach for achieving stable incorporation and controlled release of essential oils, holding broad application prospects in the field of active packaging. Future efforts should further focus on the evaluation of food sensory quality, low-cost large-scale preparation, and regulation of release behavior under dynamic storage environments, in order to promote their large-scale and standardized application in food packaging materials.
