title: Moisture‐Absorbent Food Packaging Systems and the Role of Chitosan
abstract: By lowering the amount of moisture inside the container, moisture-absorbent food packaging systems are one form of packaging technology intended to increase the shelf life of food items. These packaging techniques often incorporate a moisture-absorbing substance, such as silica gel or activated charcoal, polyvinyl alcohol (PVA), starch copolymers, cellulose-based biopolymers and chitosan biopolymers, which are inserted within the package to absorb excess moisture and avoid spoilage. Since they p
