Extending the viability of foods’ resources has a long history, helping communities to survive periods of shortage. Today, the techniques of food preservation have evolved but are no less important in conserving the nutritional value of the food as well as the investment in labour and energy.

Heat sterilisation using autoclaves has enabled food products to last, in extreme cases, for years without refrigeration. Even with the trend away from traditional rigid packaging towards lightweight pouches, such as containers and laminated cartons, the same preservation performance, without the weight and transportation demands, is possible.
