The purpose of this work was to determine the shelf life of Burlat cherries packaged in modified atmospheresduring transportation and commercialisation. Cherries were harvested at commercial maturity and packaged in trays covered with polypropylene films with different permeabilities. All cherries were transported in a refrigerated truck from Zaragoza (Spain) to Milán (Italy) during a transport time of 5 days. After transportation, cherries were submitted to a commercialisation period. Our results show thatmodified atmospherepackaging using polypropylene films of intermediate permeability (238 ml O2 m-2 h-1 atm-1 or 423 ml O2 m-2 h-1 atm-1) extends postharvest cherry shelf life up to 15–20 days at 5 °C. Under these conditions acidity levels remain higher, anthocyanin synthesis is reduced, lower level of oxidative enzymes are detected, and texture and sensorial quality improve. Moreover, films of intermediate permeability allow a temporal breakage of the cold chain without any reduction in sensorial quality of the cherries.
