Shelf Life Testing
Shelf Life Testing is a process used in the food and beverage industry to determine how long products can stay fresh and safe for consumption. It involves checking products over time to see how their taste, appearance, safety, and quality change. This helps companies decide expiration dates and ensure their products meet quality standards. Think of it like a time experiment that shows how products age under different storage conditions. Companies need professionals who can run these tests and interpret the results to make sure products are safe and maintain their quality from production until they reach consumers.
