Résumé

A test was done to determine the changes in colour and aroma of Kladno cooked pork loin stored in a refrigerator and at room temperature. No change was observed in the L co-ordinate during storage. A decrease in a co-ordinate for red colour took place after 1-day storage for the samples stored in a room. Conversely, an increase in b co-ordinate for yellow colour was observed after a 1-day storage period. A change in the cooked pork loin aroma was also noticed after 1-day storage, using sensory evaluation. Further, a portable scanner was used for the determination of colour changes in bananas. It was found that the optimal storage temperature from the peel colour point of view is 14 °C; it is in accordance with the recommendations in the literature.
