Abstract:

The study was under taken to assess the impact of differential in-pack gaseous conditions generated through modified atmosphere packaging (MAP) using different packaging films (low density polyethylene (LDPE) and polypropylene (PP), having thickness 150 guage and bag area 0.14m2) with and without perforations and variable head space (HS) on the quality of broccoli stored for 10 days at 15°C and relative humidity (RH) of 75%. Quality of stored broccoli was adjudged on the basis of retention of chlorophyll for all the packaging treatments, for the storage period. Quality parameters viz., β carotene and ascorbic acid that affect the chlorophyll retention were also recorded. The final retention levels of quality parameters were influenced by package gaseous condition. The Chlorophyll and -carotene retention were recorded better in perforated LDPE film packages having 0.8 HS than in PP film packages at the end of storage period. Similar results were recorded for ascorbic acid i.e. higher values in perforated LDPE packages having 0.8 HS. The low in-pack O2 concentration (approximately 4-5 %) along with high CO2 concentration (approximately 9-11 %) may have enhanced the retention of antioxidant components i.e. -carotene and ascorbic acid for longer period, which in turn have resulted in increase in chlorophyll retention. The results indicated that packaging film permeability for O2 and CO2 or head space might be such that equilibrated O2 concentration remains near to 4-5% and CO2 concentration to 9-11%, so as to affect a beneficial retention of chlorophyll with lesser browning.
