Kinetics of ascorbic acid loss as a function of storage temperature (30, 35 and 40°C) and water activity of intermediate moisture pineapple slices at aW of 0.92, 0.95 and 0.97 was modelled. Loss was faster at higher aW but storage temperatures of 30 ‐ 40°C had little effect at the same aw. Colour changes were larger than flavour changes. Spoilage was only a problem at high aw.
