What does "shelf life" signify in regard to food?

The concept of "shelf life" in relation to food refers to the length of time that a food product can be safely stored before it becomes unsafe to eat. This includes considerations of spoilage, quality degradation, and potential foodborne illness risks. Foods have specific shelf lives influenced by their composition, storage conditions, and packaging, which determine how long they maintain safety and optimal quality.

When food is stored beyond its designated shelf life, it may not only lose its flavor and nutritional value but could also pose health risks due to the growth of harmful microorganisms. Therefore, understanding shelf life is crucial for food safety, inventory management, and ensuring that consumers enjoy safe and high-quality products.
