INTRODUCTION
Shelf life is a complex concept that is dependent on the nature of the food product
under consideration, the preservation technologies applied, and the environmental
conditions to which the food product is exposed. In the case of packaged foods, the
packaging often plays a key role in maintaining the quality and shelf life of foods
by serving as an integral part of the preservation system employed. Ensuring high
quality products is essential for consumer satisfaction, and quality may depend
