Answer-The thermal conductivity of food is influenced by

Cell structure Fibrous foods e.g., meat conduct heat directionally 0.5WmK. Moisture Water 0.6 WmK increases conductivity vs. dry foods 0.05 WmK. Environment Pressure cooking conductivity by 30. Critical for designing heat processing canning, pasteurization.
