4. Conclusions
In summary, the essential oils of carrot juice with different
treatments were rich in carotol, sabinene and b-caryophyllene,
possessed good antibacterial activity against 8 selected food-borne
pathogens in this study. The results of this study clearly showed
that three processing units have a significant effect on chemical
composition and antimicrobial activity of carrot juice essential
oil. Based on the present research, it could be concluded that the
essential oil of carrot juice has great potential for application as a
natural antimicrobial agent. To the best of our knowledge, this is
the first report to study the effect of three processing units (blanching,
enzyme liquefaction, and pasteurisation) on chemical composition
and antimicrobial activity of carrot juice essential oil. Further
research is still necessary to fully understand the mechanisms
involved including against other food-borne pathogens, TEM
observation as well as the interactions with other food ingredients
in order to justify the real applications of essential oil from carrot
juice in food practices as a natural antibacterial agent.
