Determination and modeling of thermal properties of tofu

Thermal properties of tofu were determined in the temperature range of 5-80degreesC (10-105degreesC for specific heat) and the moisture content range of 0.3-0.7 (wb). Thermal conductivity (k: 0.24-0.43 Wm(-1)K(-1)) and thermal diffusivity (alpha: 7.6 x 10(-8) 1.15 x 10(-7) m(2) s(-1)) were measured simultaneously using dual probe method, and specific heat (C(p): 2.52-3.69 kJ kg(-1) K(-1)) with modulated differential scanning calorimetry. Good agreement was observed between perpendicular model and the thermal conductivity data, but not with parallel model. Simple empirical models were also developed as a function of the moisture content and temperature of the tofu.
