Broccoli inflorescences are rich in health-promoting compounds such as vitamin C which may contribute to the high antioxidant capacity found in freshly-harvested broccoli. However, high losses of this essential compound has been reported after harvesting. Modified atmosphere packaging (MAP) is the way that controls respiration rate of product through decrease in O2 and increase in CO2 levels to maintain quality and increase in storage life. Broccoli (Broccoli oleracea L. var. premium crop) were packaged using two type of polymeric films (polyethylene and polypropylene), and then stored at 1°C for 18 days to study the effect of passive and active MAP(1.5%O2+7.5%CO2). Fermentation products, ascorbic acid, chlorophyll, rate of ethylene production and some quality attributes were measured and estimated every 3 days. The results indicated that modified atmosphere packaging significantly prolonged storability up to 18 days with high quality attributes and Minimized ascorbic acid losses during the whole period.
