FOOD SIMULANT MATERIAL FOR TEMPERATURE CONTROL SENSOR

摘要

A food simulant material of the type into which temperature sensors can be inserted in a refrigeration system, so that the temperature measured reflects that of food stored in the system, comprises a solid wax in which are distributed gas-filled polymeric particles. The wax is a food-grade wax such as cheese wax and the polymer particles are preferably air-filled polystyrene microcapsules of mean particle diameter 50-500 µm.
