Accelerated shelf life testing is often conducted to predict how food products will behave in the retail network. If a product is expected to maintain acceptable quality for 6 months at 30 C, how long should this product be stored at 45 C prior to testing so that the results will be equivalent to those obtained after storage of 6 months at 30 C. From a previous test, Q10 for the product in the temperature range under consideration was determined to be 6.3.
