Abstract
The shelf life of the food was actually period in which the product is considered suitable for consumption. By understanding the factors that influenceto the shelf life of the product, it is possible manipulation of these factors in order to extend the shelf life of the product. There are several factors that affect the shelf life such as: the manufacture of the product, freezing , chemical changes, as well as, food packaging. These factors can contribute to reducing the amount of food that is thrown away because of the short shelf life. There is scientific basis for assessing the shelf life using mathematical expressions that are useful in predicting the degradation of food products during storage. It is based on the principles of chemical kinetics. Actually, the changes in the quality (Q) can be observed and measured over time. The shelf life of the food products based on changes in quality in relation to the time can follow kinetics of zero order or first order. Using these calculations the phases of reducing the quality and accuracy of the product can be predicted.
