ABSTRACT To measure temperature‐dependent thermal conductivity of surimi, a line‐source probe system was developed. Effects of test conditions and sample history were investigated. Thermal conductivity of Alaska pollock surimi having 0, 4, 6, 8, and 12% cryoprotectant levels was measured in the range ‐40 to 30°C. Thermal conductivity of surimi has a relatively weak dependence upon cryoprotectant level when water content of the sample is controlled at 80.3%. From measured data, the Schwartzberg model and its modification were selected for future prediction. Three parameters in the model, T i , B, and K′ f had a linear variation with cryoprotectant concentration.
