 The novel concept of distributing the food super chilled (partially frozen) in order to prolong the shelf life has been suggested in the project. The temperature of the distribution chain is envisaged to be +5C. The suggested application has the following advantages: 1) Partial thawing of the product in the distribution chain makes it easier to handle. 2) The unhealthy and labour-demanding operations in professional kitchens can be reduced, therefore, the quality loss can be minimised. 3) High thermal buffering capacity of partially frozen foods as compared with chilled foods makes them robust against temperature fluctuations. 4) The temperature gradient is positive throughout the distribution chain because the outside temperature is always greater than the product temperature.The introduction of new technological solutions in the food sector should be sustainable in a broad sense. The solution should give top priority to optimization, while at the same time due considerations must be taken to food safety and the three Ps of sustainability: people, profit and planet earth The introduction of new technological solutions in the food sector should be sustainable in a broad sense.
