[Objective] The aim was to study the kinetics of quality of shiitake under different temperatures and establish the mathematical model of quality indexed and shelf life of shiitake.[Method] With shiitake as the material,the change of free amino acids content,pH and browning intensity under stored temperatures of 273,283 and 293 K were studied.And from which the freshness indexes of shiitake was selected to establish the mathematical model of quality indexes and shelf life.[Result] During storage,the free am...
