A range from 0°C to 3°C is recommended as the optimal temperature for cold storage of apples; however, practically, it seems to be impossible to maintain a consistent temperature throughout the supply chain after harvest Sub-optimal temperatures during handling stages can cause unpredictable loss of quality. The aims of the study were to investigate responses of the stiffness in "Cripps Pink" (Malus pumila Mill.) apples under a wide range of temperatures, including the optimum temperature and establish the best mathematical model to characterize the softening process and predict change in stiffness of the apples during storage. 'Cripps Pink' apples were stored under regular air at six temperatures from 0°C to 30°C over 9 months from May, 2005. Stiffness of the apples was recorded periodically by the acoustic firmness sensor (AWETA,
