accelerating factors are temperature and/or humidity, water
activity and atmosphere. These factors are selected depending
on the product and its usual storage conditions. For
example, temperature has been used to accelerate changes
during storage in tomato concentrate (Pedro and Ferreira
2006) and human milk replacement formula (Curia and
Hough 2009), while a combination of oxygen partial pressure,
water activity and temperature have been used to
accelerate changes in coffee during storage (Cardelli and
Labuza 2001). Fruit-filled snack bars are generally stored in
vapor-proof packaging; therefore, in this case, temperature
