The shelf life of a product is defined as the practical time that it remains desirable to consumers. Correctly determining the shelf life of a product can be a challenging endeavor, often due to a lack of resources and clear guidelines for conducting shelf life testing. The shelf life simplified paradigm takes a pragmatic approach to shelf life determination by using the relationship between water activity and shelf life to guide the process.
