This chapter discusses relevant antimicrobial compounds derived from marine algae, with emphasis on their important antibacterial and antifungal properties, as well as their inhibitory properties on various enzymes and mycotoxins.

This chapter describes the efficacy of the following plant-derived compounds and products against postharvest diseases of fruits caused mainly by pathogenic fungi: volatile compounds, essential oils, glucosinolates, jasmonates and plant extracts. Future perspectives on the use of plant products as alternatives to fungicides against postharvest diseases are briefly covered.

This chapter describes various approaches in the predictive modelling of the antimicrobial effects of natural aromatic compounds in model and food systems. The applications of primary models (growth models and survival models) and secondary models in the antimicrobial assessment of essential oil effects are covered. Future perspectives on the application of mathematical models in the assessment of the antimicrobial activities of essential oils are briefly discussed.
