Aims: The antifungal activity of trans ‐2‐hexenal on Aspergillus flavus in a model system in relation to its concentration, incubation temperature and a w was assessed. Methods and Results: A model describing the antifungal activity of the aldehyde in relation to these variables was obtained. Conclusions: According to this model, the inhibition of A. flavus was weakly dependent on the incubation temperature (at least within the range of values considered) and strongly affected by the trans ‐2‐hexenal concentration and a w , which showed a remarkable synergistic effect. Significance and Impact of the Study: Trans ‐2‐hexenal proved to be a molecule with remarkable antimicrobial properties, even when added in closed systems at low concentration.
