Effect of different packaging methods in storability of broccoli var. Aishwarya in refrigerated condition
Abstract: Research work was conducted within the laboratory of Post Harvest Technology of Horticultural Crops Department, Bidhan Chandra Krishi Viswavidyalaya, Mohanpur after harvesting broccoli which was grown within the Horticulture Research Station, Mondouri to determine the effect of different packaging materials on the post harvest life of broccoli stored in refrigerated condition(5±1ºC) and 90-95%relative humidity. Freshly harvested broccolies were trimmed and packed in polypropylene (100 gauge), polyethylene bags(150 gauge) with and without perforation, corrugated fibreboard boxes with inside laminated, stress wrap (50 gauge) and in control to determine the difference in post harvest life of broccoli. During the storage period, samples were taken at regular interval to determine the physiological loss in weight, chlorophyll loss, yellowing %, fungal decay or bacterial decay, sensory evaluation for colour, smell, texture and browning along with marketability. The loss in weight was least in polypropylene bag with no perforation and in stretch wrapped broccoli. Chlorophyll content was high in polypropylene bag with no perforation and polyethylene bag with 1% perforation while yellowing occurred in all packaging where perforation was given and the maximum was in unpacked broccoli. On sensory analysis, best visual colour was in stretch wrapped broccoli, with good smell score in polypropylene and polyethylene bag with no perforation.
