Summary

In this work, strawberries packaged in clamshell containers and a variety of tray designs were precooled in commercial cooling systems. To determine the speed of cooling for each treatment, both the 7/8th cooling time and the cooling coefficient were calculated. It was found that the control package combination (with a design that fits six trays per pallet layer) cooled significantly faster than the other treatments, which fit five trays per pallet layer. It is thought that the cross-orientation of trays that occurs in the five trays per layer configuration may slow cooling if the vents are not designed properly. No major differences were found for cooling using corrugated trays versus returnable plastic containers. It was found that the clamshell container and tray should be designed together and chosen properly to allow maximum air-to-product contact during cooling. Variations in air temperature during commercial cooling tests may cause errors in determining 7/8 the cooling times.
