Effect of modified atmosphere packaging (MAP) on the quality of greengrocery during the cold storage

Modified atmosphere (MA) storage is a useful technique to extend vegetable shelf-life.The aim of this work was to select the most suitable air condition for packaging greengrocery.Samples were stored at 4℃, under different atmospheric conditions (normal atmospheric air, 10% CO2+20% O2+70% N2, 10% CO2+5% O2+85% N2, 10% CO2+1% O2+89% N2, 5% CO2+5% O2+90% N2, 15% CO2+10% O2+85% N2) , and analyzed periodically for the sensory index, chlorophyll, nitrite, total soluble solids, conductivity.The result indicated that the air composition 10% CO2+5% O2+85% N2 at 4℃ was selected as the best one to extend shelf-life and preserve the nutritive value of greengrocery.
