4. Conclusion
The ability of CDs to retain EOs and reduce their volatility was
demonstrated. The “rapid method” based on SH-GC technique was
successfully applied and validated for studying the interactions
between CDs and individual components present simultaneously
in EOs. Kf values of inclusion complexes between six CDs and
eleven volatile compounds present in nine EOs were determined.
The assessment of Kf values for CD inclusion complexes with EOs
components is of major interest for choosing the well-suited CD.
In addition, encapsulation within CDs reduced the volatility and
allowed the controlled release of EOs components as demonstrated
by MHE. Moreover, in the presence of CD, EOs showed higher radical
scavenging efficacy. Our results suggested that CD inclusion
complexes could overcome limitations of EOs application in food
by reducing their volatility and lost during storage or food process
and enhancing their radical scavenging ability. Thus, they could
generate controlled release systems for food packaging use as well
as for improved aroma differentiation and aroma burst.
