Abstract: The activity of antifreeze protein (AFP) in Tenebrio molitor is analyzed by differential scanning calorimetry (DSC). It is shown that the antifreeze activity of AFP increases with decrease of initial ice crystal， and increase of concentration of AFP. These results are accordant with the absorption-inhibition mechanism of AFP.
