An experiment was carried out to study effect
of pre-cooling on post harvest life of mango cv. Kesar at the
Post Graduate Laboratory of the Department of Horticulture,
Junagadh Agricultural University, Junagadh. The results of
the study indicated that mango fruits treated with different
pre-cooling treatment showed lower and slower rate in
physical and chemical changes than control fruits. The fruits
treated with pre-cooling at 8ºC for 8 hr proved to be most
effective with respect to more number of days taken to ripe
(11.50), longer shelf life (17.49 days), lower spoilage
(20.55 %) and higher percentage of marketable fruits
(55.48 %) and recorded less physiological loss in weight
(21.59 %) and more firmness of fruits (0.79 kg cm-2) at 20th
days after storage. The treatment was also found promising
for slower increase in TSS, reducing sugar and total sugar,
while slower decrease in ascorbic acid and acidity during
storage. The organoleptic rating with regard to colour, taste
and overall acceptability was also found significantly higher
in pre-cooling at 8ºC for 8 hr treated fruits.
