The effect of propionic acid, its sodium salt or a commercial formulation of propionates (0.03, 0.05 and 0.07%), on growth and FB1 production by Fusarium verticillioides and F. proliferatum isolates was evaluated on irradiated maize at different water activities and temperatures. None of the assayed treatments had any effect on FB1 production by F. verticillioides isolates. For F. proliferatum, higher FB1 production occurred in the absence of propionates, and in general concentration decreased with increasing doses of preservatives. Single factors (aw, propionate concentrations and temperature) and temperature x aw, and propionate concentration x temperature interactions had a significant effect on fumonisin production. Moreover, propionate concentration was the single most important factor, besides temperature, which affected FB1 production.
