Antimicrobial and antioxidant activities of <i>Cinnamomum cassia</i> essential oil and its application in food preservation

Abstract This study was designed to investigate chemical and antioxidant properties, as well the antimicrobial antibiofilm behaviour of Cinnamomum cassia essential oil (CCEO). MALDI-TOF MS Biotyper mass spectrometry applied evaluate biofilms Stenotrophonomonas maltophilia Bacillus subtilis , while ability CCEO assessed on wooden glass surfaces. The activity by disc diffusion method, microdilution vapour phase for two biofilm-producing bacteria three Penicillium spp. were used. Antimicrobial properties using agar protocol. citrinum, P. crustosum, expansum, S. maltophilia, B. bread, carrot, potato, sweet apple in situ studied. Specific molecular variations related biofilm formation genetic analogies evaluated with MSP spectra dendrograms profiles grown different days. results broth methods showed that strongly effective against all tested microorganisms method active spp., but not food preservation matrices.
