Physical characteristics like moisture content, PLW, peel thickness, colour,
puncture and cutting forces of four different citrus species namely, Jatti khatti (Citrus
jambhiri Lush.), Soh sarkar (Citrus karna Raf.), grapefruit (Citrus paradisi Macfad.),
pummelo (Citrus grandis Osbeck) stored at ambient and refrigerated conditions were
determined. It was found that there were significant differences in physical
characteristics among the citrus species viz pumello, grapefruit, Soh sarkar and Jatti
khatti. It was observed that the pummelo had the largest fruit size (106.41 x 112.35
mm) whereas the size of Soh sarkar, grapefruit, Jatti khatti were 86.52 x 84.20 mm,
79.96 x 70.65 mm, and 63.68 x 59.82 mm respectively. It was also revealed on the
basis of PLW (10%) that Jatti khati, Soh sarkar, grapefruit and pummelo could be
stored upto 4, 3, 8 and 10 days, respectively in ambient condition but in refrigerated
condition the storage life could be extended in Soh sarkar and pummelo up to 20 and
25 days days, and in Jatti khatti and grapefruit up to 15 and 30 days, respectively.
These physical characteristics were also significantly affected by storage days as well
as storage conditions. Citrus fruits stored at ambient condition deteriorated more
rapidly than the refrigerated fruit. As soon as physiological loss in weight of fruit
increased, moisture content, peel thickness as well as juice percentage of fruit
increased and also changed occur in peel colour in both the storage conditions. Less
puncture as well cutting force were required in all four species in refrigerated
condition than ambient condition.
