In this study, the effects of modified atmosphere packaging (MAP) on the shelf -life and quality characteristics of Belstar and Beaumont broccoli cvs. grown in T ekirdağ ecology were evaluated. Packaged broccoli crowns and control groups were stored at 2±1 oC and 90-95% relative humidity for 4 weeks. Variations in weight loss, total phenolic compound content, antioxidant content, total chlorophyll content and external appearance were determined during cold storage period at weekly intervals. As a result of the research, the weight loss of the control group crowns was higher than that of the crowns which was kept in the modified atmosphere packs.. In both cultivars examined, although variations were observed in terms of total phenolic compound, antioxidant capacity and total chlorophyll content during storage; it was found that the MAP applied heads of both cultivars had higher contents at the end of storage period. During cold storage, significant losses in appearance in both control group and MAP treated heads were observed. But with the MAP application, the loss from external appearance is limited. Thus, it can be suggested that the MAP can be used as a tool to maintain the quality of broccoli crowns stored in the cold.
