Abstract
The present investigation was carried out at the Post Harvest
Laboratory of the Department of Horticulture at CCS Haryana
Agricultural University during the year 2005. The main objective was to
enhance the shelf-life of pear fruits of varieties i.e. Patharnakh, Kashmiri
Nakh and Baggugosha under zero energy chamber using different types
of packaging materials viz., corrugated fibre board boxes, polyethylene
bags of individual fruit packing (0.01 mm and 0.05 mm) and
polyethylene bags of 1 kg capacity (.0.01 mm and 0.05 mm). PE 0.01 mm
of individual fruit packing at zero energy chamber storage was most
effective in checking the PLW and decay loss. There was continuous
decrease in firmness, specific gravity, acidity, ascorbic acid and
chlorophyll content irrespective of the packaging treatments. However,
TSS, sugars and carotenoids content showed an increasing trend.
Penicillium sp., Physalospora sp. and Botrytis sp. were the main causal
organism responsible for the decay.
Among different varieties Patharnakh was found to have longer
shelf-life on PLW and decay loss basis and out of different packaging
materials, pear fruit packed in PE 0.01 mm and PE 0.05 mm of
individual fruit packing at zero energy chamber storage were the best in
maintaining physical, biochemical and pathological parameters up to
10th day of storage. Whereas, maximum degradation of fruits was found
in CFB boxes stored at room temperature.
