Abstract

The influences of four different cooking methods-pan, ohmic, vacuum and sous vide-were studied with regard to the microstructural, sensorial and physicochemical characteristics of pork meat. The end point temperature to all cooking methods was 70 °C. Pan cooking resulted in a softer meat with higher overall liking by the consumers, and ohmic cooking produced firmer (p < .05) meats and myofibrils, with higher alignment compared to the pan-cooked meat as well as a golden colour. Sous vide-cooked meats were perceived as insipid, while vacuum-cooked meats showed loss of structure and were perceived as drier (p < .01) and paler (p < .01). No statistically significant differences were found for cooking loss and water-holding capacity (p > .05). The results suggest that consumers preferred pan-cooking, as they described these samples as juicy, tender and tasty. Ohmic-cooked meat, which required shorter cooking times, showed similar characteristics to pan-cooked meat and could be used as alternative to pan cooking in the catering industry.
