Summary

Fresh food quality and safety are influenced by temperature variation in the food chain. Phase change materials (PCM) in packaging contributes to preserve food quality and extending food shelf life. A transient 3D CFD model was developed to predict the thermal performance of fruit packaging boxes with PCM alveoli. The thermal performance is analysed during the cooling period (storage inside cooling chamber) and heating period (packaging is exposed to ambient conditions). Results are evaluated for an 8-hour and 10-hour cooling and heating periods respectively. Numerical results are validated by experimental tests with and without PCM. Results show that packaging boxes with PCM alveoli allow fruits to heat at a slower rate when exposed to non-ideal temperatures. The PCM stores energy and works like a thermal capacitor allowing the fruits to be conserved for a longer period helping to maintaining ideal temperatures, which results in shelf life extension of fresh products.
