The effect of storage temperature and water activity on aflatoxin B accumulation in hull-less and hulled spelt grains.

Background: In concomitance with shifts in climate conditions in recent years, an increasingly frequent emergence of Aspergillus flavus and aflatoxins in cereals has been observed. In this study the effects of temperature (15, 23, 30 and 37 °C) and water activity (a ) (0.85, 0.
