Resumen:
The influence of the passive and active modified atmosphere packaging (MAP) on the yellowing and the activity of the enzymes involved in the chlorophyll (Chl) degradation of fresh-cut rocket was studied, during storage at 5 °C. As control, fresh-cut rocket packaged in perforated plastic film were used. Their respiratory rate, ethylene production, yellowing degree, color, Chl, pheophytins (Phy) as well as the chlorophyllase (Chlase), Mg-dechelatase and Chlorophyll-degrading peroxidase (Chl-POX) enzymatic activity were assessed during the storage. The control showed increased yellowing degree and reached the limit of sensory acceptability at seven days while the active MAPs samples remained with acceptable values even at 15 days. The lower Chl degradation in fresh-cut rocket stored under active MAP (3 kPa O2 + 5 kPa CO2 or 5 kPa O2 + 20 kPa CO2) might mainly be due to the senescence delay induced by the atmospheres used and the lower Chlase activity.
