This study was carried out to ascertain the effect of different concentrations of ozone (0.2, 0.4 and 0.6 ppm
ozonated water) on postharvest quality of summer squash fruit during cold storage at 8 ± 2ºC temperature
and 85-90% relative humidity. Various physico-chemical quality traits were recorded at a regular interval of
3 days upto 12 days of fruit storage. Among the applied doses of ozone, 0.4 ppm ozone concentration was
found better in retaining higher fruit firmness (5.84 N) and maintaining lower weight loss (15.06%) over control
fruits during storage of 12 days. However, total bacterial count (3.92 log cfu/g); yeast & mould count (3.65 log
cfu/g) and decay incidence (%) were effectively controlled by 0.6 ppm ozone concentration. Contrast to these
gainful impact of ozone application on firmness, physiology and microbial load; the colour of the stored fruit
was masked even by 0.2 ppm ozone.
