Abstract
Jackfruit (Artocarpus heterophyllus L) is probably the biggest fruit. In the fresh form, the fruit is highly perishable, difficult to separate the fruit-lets and the huge size poses transportation problems. Technology development on vacuum packaging of minimally processed jackfruit bulbs was undertaken to test its quality and potentiality to withstand long distance transportation. Pre-treatments with citric acid, packaging using PE (300 gauges), vacuum packaging at different percentages (60%, 70% and 80%) and storage temperatures (3-5 and -12 0C) were imposed to enhance the post harvest shelf-life and to maintain the quality of jackfruit bulbs. Control samples without pre-treatment were stored in the same environmental conditions. Analysis of variance using the (Agress) at 5 % level of significance showed that there was a significant difference between experimental different vacuum percentage samples and the control. Vacuum packaged sample at 80% was found to be best for unripe bulbs, 75% for semi-ripe bulbs and 70% for ripe jackfruit bulbs for long distance transportation. Among the 3 modes of transportation studied (bus, jeep and train), transportation by train was found to be the best in maintaining quality of minimally processed jackfruit bulbs. Deep freeze storage (-12 0C) resulted in a longer shelf-life than refrigeration storage. Vacuum packaging enhanced the shelf-life of the minimally processed jackfruit bulbs up to 3-4 weeks in refrigeration storage (3-5 0C) and over 6 weeks in deep freeze storage (-12 0C). The cost: benefit ratio for vacuum packaging of the minimally processed jackfruit bulbs was calculated to be 1.0: 3.82.
