For the selection of heating and refrigeration equipment, as well as the optimization of the components of the production line intended for the processing of meat semi-finished products, detailed information on the dependencies of the main characteristics of the products is required. Such characteristics include physico-mechanical, thermophysical, technological and many others. The authors present the methodological foundations of measurements, approaches to sample preparation and the results of an experimental study of the thermal conductivity and specific heat capacity of an organic emulsion. The analysis of methods and laboratory equipment for measurements taking into account the object of research was carried out. The peculiarity of the sample under study is the variable fractional composition, as well as the presence of a liquid phase in the form of water. This makes it impossible to use standard commercially available mandrels for samples. To study the characteristics of the organic emulsion, the method of stationary heat flow and the method of differential scanning calorimetry were chosen. As a result of the research, the nature of the measurement of specific heat capacity and thermal conductivity in the temperature range from -5 to 90 °C. The specific heat capacity of the sample varies from 2800 to 4410 J/(kg·K), while a phase transition of crystallization/melting of the water phase was observed. The approximation method was used to exclude it. The values of thermal conductivity vary from 0,28 to 0,49 W/(m·K).
