Microencapsulation of eugenol molecules by β-cyclodextrine as a thermal protection method of antibacterial action.

Eugenol is natural oil that has excellent antibacterial properties but cannot be used to fabricate many products that require thermal processing. One possible alternative to the use of the eugenol molecules in high-temperature processes is the encapsulation of these molecules in a structure that is not toxic and is resistant to thermal treatment. This work investigated the encapsulation process of eugenol molecules in β-cyclodextrine and the antibacterial properties of eugenol-β-cyclodextrine (the eugenol-βCD complex) against Escherichia coli and Staphylococcus aureus.
