Abstract: The study presented the energy and environmental performance of cryogenic refrigeration for frozen food applications and discussed the standard and cryogenic cooling performances of fruit and vegetable products with an entropy-based approach. In cryogenic processes, exergy efficiency has been shown to have a potential of 2.56 times higher than standard applications. On the other hand, when the environmental indicators according to entropy productions were examined, it was seen that the environmental pollution potential of cryogenic processes was 32.37% less than standard practice. At the end of the study, the sustainability effects of cryogenic cooling were also evaluated.

Keywords: frozen food; exergy; entropy; environmental performance; sustainability.
