Shelf life

Shelf life refers to the length of time a product remains usable, fit for consumption, or saleable under specified storage conditions. Shelf life is influenced by factors including temperature, humidity, light exposure, and packaging materials, which can accelerate chemical or microbial degradation. Manufacturers determine shelf life through stability testing and often label products with "best before" or "use by" dates. Proper storage and handling can extend shelf life, while deviations can lead to spoilage or diminished quality.
