The discussion of the energy crisis for a steadily growing population is often limited to scarce amounts of electric power based on more or less environmentally friendly energy sources. However, lack of food, and in particular fresh food, is also part of the current energy crisis. Fresh food is one of the most valuable sources of energy and broad research and technology development is constantly ongoing to protect and utilise fresh food for human consumption in an energy efficient way.
The challenge for the food industry is consequently to conserve and utilise fresh food to give a high quality product, defeating the barriers of costs and varying storage/transport conditions. During the past decade, superchilling of fresh food has come up as an alternative and supplement to traditional conservation methods like freezing and chilling, and the R&D results for superchilling technology are promising.
