摘要：The high hydrostatic pressure treatment on sea cucumber has many advantages over traditional processes and it has a promising future. Effects of processing parameters on holothurians autoenzyme activity were investigated within the range of the parameters: the processing pressure of 0.1~550MPa, the pressure-keeping time of 0~30min, the processing temperature of 24~62°C.Under the room temperature and pressure-keeping time of 20min, the autoenzyme activity decreased to 88.25% at 200MPa, increased to 106.77% at 250MPa, and reached the lowest level of 29.81% at 550MPa.The holothurians autoenzyme activity increased first and then decreased with the increasing of pressure-keeping time and temperature. The effect of pressure-keeping mode on holothurians autoenzyme activity was not significant. The BP artificial neural network was used to predict the effects of high pressure on holothurians autoenzyme. Compared with the experimental results, the average relative error of predicted results was 0.9%.The experimental results show that the holothurians autoenzyme can be activated and inactivated at certain pressure, pressure-keeping time and temperature. The study provides some valuable information for optimizing the high hydrostatic pressure treatment of holothurians autoenzyme inactivation.
