Research on the suitability of modified atmosphere packaging for shelf-life and quality improvement of apricot fruit

摘要

Fruits from the cultivars Beliana and Rouge du Roussillon were packed in punnets (650 g fruit) then placed in plastic film bags having permeabilities ranging from 40 000 to 120 000 ml gas (24 h)-1m-2atm-1 and stored at temperatures ranging from 5 to20℃. The composition of the internal atmosphere depended on the film's permeability; the higher the permeability the higher the O2 level and the lower the CO2 level. A higher permeability allowed the steady state to be reached more rapidly. Temperaturealso affected the composition; the higher the temperature the lower the O2 concentration and the higher the CO2 concentration. The steady state was also reached more quickly for a given permeability at a higher temperature. There were marked differencesin the internal atmosphere between cultivars, these differences decreasing as the permeability increased.
