Progress on the Antimicrobial Activity Research of Clove Oil and Eugenol in the Food Antisepsis Field

As potential and valuable antiseptics in the food industry, clove oil and its main effective composition eugenol show beneficial advantages on antibacterial and antifungal activity, aromaticity, and safety. Researches find that both clove oil and eugenol express significantly inhibitory effects on numerous kinds of food source microorganisms, and the mechanisms are associated with reducing the migratory and adhesion and inhibiting the synthesis of biofilm and various virulence factors of these microorganisms. Clove oil and eugenol are generally regarded as safe in vivo experiments. However, they may express certain cytotoxicity on fibroblasts and other cells in vitro. Studies on the quality and additive standard of clove oil and eugenol should be strengthened to promote the antiseptic effects of them in the food antiseptic field.
