Orange juice is aseptically packed in multilayer carton boxes. At the moment of packing the juice contained minimum 50 mg. vitamin C per 100 g. The label claims a vitamin C content of 40 mg per 100 g. What must be the maximal storage temperature, if the product has to comply with the claim on the label after 180 days of storage? Assume that the loss of Vitamin C follows a first-order kinetics with a rate constant of k=0.00441 day and an energy of activation of E = 70,000 kJ kmol, at 27°C.
