Abstract: In the present study, application of mathematical method to the design of modified atmosphere packaging (MAP) for the transportation of fresh farm produce from a supplier to a retail shop in a distribution chain is presented through a case study involving transportation of fresh broccoli from a supplier to final consumers. The study examined the suitable distribution chain that would ensure the remaining shelf-life of the broccoli meets the consumers' requirement at the time of delivery. The developed model was based on macro-balance of mass and heat transfer. Results from the numerical simulation of the developed model suggest that transportation of the broccoli by air is better than the transportation by water. In addition, a packaging material with oxygen permeability of kO2 = 0.7 kO2max is specified to ensure that the shelf-life of 5 days for the brocolli is met after the delivery.
