Abstract

The test with colour and aroma of Kladno cooked pork loin stored in refrigerator and at the room temperature correspond with its spoilage was done. No change of the L* co-ordinate has been observed during the storage. A strong decrease of a* co-ordinate for red colour after 1-day storage has taken place for samples stored in a room (approx. 25°C). Conversely, an increase of b* coordinate for yellow colour has been observed after 1-day storage. A change of the cooked pork loin aroma has also been noticed after 1-day storage using the sensory observation. Further, the possibility has been tested of using a portable scanner for the determination of banana colour changes. It has been found that the optimal storage temperature from the peel colour point of view is 14°C; it is in accordance with recommendations in literature.
