Temperature Response of Frozen Peas to Di‐Thermal Storage Regimes

A mathematical model was developed for prediction of temperature fluctuations in warehouse stacks of frozen peas subjected to dithermal storage regimes. The model was tested by comparing its predictions with temperatures measured in frozen peas packed into a slab‐shaped container. Satisfactory agreement was found between model and experiment. Other model predictions indicate that large container sizes and rapid fluctuation regimes result in the greatest thermal stability at interior locations in bulk‐stored peas. Thermal properties of frozen peas were also determined as part of the experimental verification. The model can be used to evaluate quality changes in frozen products due to di‐thermal storage and the energy needed to maintain a certain final quality.
