Carbon dioxide (CO2) and nitrogen (N2) are commonly used in packaging both fresh and shelf-stable foods, in order to extend their usable shelf lives. Fresh foods are outside the scope of this work so attention shall be focused only on those foods suitable for use in storage programs.
Vacuum packaging, also called Reduced Oxygen Packaging (ROP) is used because it allows for an extended shelf life in the freezer by reducing off odors and texture changes which may result in spoilage. When food is vacuum packed, air is sucked out of the packaging and then the packaging is hermetically sealed. Fish packaged this way are very popular in grocery stores, itâs important to handle the fish correctly.
