Summary

Blueberries are superfoods due to their high nutritional value. However, they are highly susceptible to mechanical and physiological damage. Packaging plays a crucial role in maintaining fruit quality throughout the supply chain. Nevertheless, temperature fluctuations and cold chain breaks occur throughout the supply chain, leading to complex heat and mass transfer phenomena and the formation of water condensation. This condensation is undesirable as it affects the fruit’s appearance, promotes microbial growth, and fruit loss. In this study, a numerical model was developed to predict air and product temperature distributions, as well as water condensation on the blueberries' surface within the bulk, when the packaging is exposed to cold chain breaks. The influence of the ventilated holes area was also examined. The model was validated against the experimental results. The results indicated that the model accurately predicts temperature distribution and water condensation. Moreover, the ventilation area affected the accumulation of water condensation.
