摘要：Thermal diffusivity of puff pastry dough was measured in the temperature range from –35 to +10 °C, by using modified Dickerson method. Thermal diffusivity of the frozen dough found to be greater than unfrozen sample and was found to be decreased with temperature for the frozen state. Empirical equation for thermal diffusivity calculations were obtained by application of regression analysis to the results for the frozen state. Thermal diffusivity of puff pastry dough was measured as 1.08 x 10-7 m²/s between 3 and 10 °C.
