Samples of pork Longissimus dorsi were cooked in an oven by air/steam cycles (FC/S) at four temperatures (100, 110, 120 and 140 degrees C). Temperature profiles, cooking loss, shear force, water holding capacity and colour were determined for all FC/S cycles and compared with those obtained on pork cooked under forced convection regimes (FC), used as reference treatment, at the corresponding temperature.

At 120 and 140 degrees C, cooked FC/S products were paler (on the upper surface) and less tender than FC samples also exhibiting a significantly higher cooking loss and lower water holding capacity. The use of FC/S treatment could be particularly attractive at lower temperatures especially at 110 degrees C in comparison with FC, where similar cooking quality (texture, colour, water holding capacity) was achieved in a shorter time.

Abstract
Samples of pork Longissimus dorsi were cooked in an oven by air/steam cycles (FC/S) at four temperatures (100, 110, 120 and 140 degrees C). Temperature profiles, cooking loss, shear force, water holding capacity and colour were determined for all FC/S cycles and compared with those obtained on pork cooked under forced convection regimes (FC), used as reference treatment, at the corresponding temperature. Thermal profiles of FC/S cycles were markedly different from FC treatments; all FC/S cooking cycles were significantly quickened by steam (RH 20-88%) and developed a greater temperature differences between centre and surface than the FC treated samples (RH 2-5%). At 120 and 140 degrees C, cooked FC/S products were paler (on the upper surface) and less tender than FC samples also exhibiting a significantly higher cooking loss and lower water holding capacity. The use of FC/S treatment could be particularly attractive at lower temperatures especially at 110 degrees C in comparison with FC, where similar cooking quality (texture, colour, water holding capacity) was achieved in a shorter time.File | Dimensione | Formato | |
