Chitosan and chitosan/k-carrageenan microspheres loaded with
P. dioica essential oil could be used to preparation of innovative meat
products with sensory and physicochemical quality improved.
The aim of the research was to study the encapsulation of the
P. dioica essential oil in chitosan and chitosan/k-carrageenan microspheres.
The main objectives of the study were the extraction of the essential
oil from P. dioica beans by means of supercritical CO2, the
identification of the compounds from P. dioica essential oil through GC
analysis, the determination of the antioxidant and antimicrobial properties
of the P. dioica essential oil, the preparation and characterization of
the microspheres loadedwith P. dioica essential oil. The swelling behaviour
of chitosan and chitosan/k-carrageenan microspheres and the release
kinetics of the essential oil were investigated too.
