Abstract

The physical properties of jackfruit were studied in which the average length and weight of jackfruit obtained was ranging between 26.28 to 50.86 cm and 2.92 to 9.20 kg. Similarly fruit diameter, core diameter and core length was between 16.22 to 30.78 cm, 3.72 to 5.46 cm and 16.18 to 37.92 cm. The rind thickness of the fruit was found to be having dimension from 1.40 to 2.30 cm. The bulb weight, seed weight, flakes weight and peel weight of a fruit was ranging from 0.68 to 3.0 kg, 0.26 to 1.04 kg, 0.43 to 0.81 kg and 1.23 to 4.35 kg. The cutting strength using HDP/BS blade probe was studied by penetrating to the rind (skin) of the fruit. The force to penetrate required for different rind thickness of the fruits ranged 15351.86 to 19983.50 g. The distance of the first peak was about 22.65 to 60.44 mm from the surface. The second positive peak was the point at which complete skin peel cut with fibrous part was occurred. It required a force of approximately 18289.06 to 35366.4 g for different fruits and the peak was observed at a skin depth of 35.49 to 48.94mm from the surface of the fruit.
