Retort processing of foods in rigid, semi rigid and flexible packaging systems is one of the most acceptable forms of preservation. It represents a unique combination of package, process and product technology with potential economic benefits. The retort pouch is constructed from a flexible metal-plastic laminate which is able to withstand thermal processing via pasteurization. The food is first prepared and then sealed into the retort pouch. The pouch is then heated to 116-121°C under high pressure.EnglishVeterinary ScienceBook chapter
