Abstract
Natural plant extracts and their principal constituents are of increasing interest. They have been applied to packaging application as antimicrobial (AM) packaging. This chapter first reviews AM activity of highlighted potential cinnamaldehyde and eugenol. Both compounds show a broad spectrum of inhibitory effect against microorganisms. Second, possible techniques, including coating, incorporation, and smart blending to design AM packaging systems related to natural plant extracts and their principal constituents, are discussed. Third, the effectiveness and applications of AM packaging based on cinnamaldehyde and eugenol on model systems and foodstuffs (e.g., seafood, bakery goods, fruits, and vegetables) are mentioned. Moreover, an alternative means for AM effectiveness determination of AM packaging containing lipophilic compound also is reported to solve a limitation of a conventional method. Last, it is likely that the future trend into a combination of naturally-derived AM agents and biodegradable packaging materials will highlight the merits of bioactive packaging.
