Summary

Concentrations of oxygen and CO2 within the packages equilibrated to about 2.5 and 8%, respectively, within 24 hours and remained almost constant over 96 hours. Reduced ascorbic acid content was significantly greater in packaged than in non-packaged broccoli (82 vs. 54% retention). Moisture content was greater (88.3 vs. 86.1%), peroxidase activity was lower (86 vs. 142%), Instron shear values were smaller (1.0 vs. 1.4 kilogramme/milimeter) and total chlorophyll retention was greater (99 vs. 37%) in packaged broccoli compared with non-packaged broccoli after 96 hours. No significant differences were found in total aerobic microorganism population growth between packaged and non-packaged broccoli.
