The study aims to use a cellular automata dynamic model with spatiotemporal features to simulate the calculation process of fruit and vegetable medium treated by a high voltage pulse electric field,and this simulation provides theoretical support for the application of high-voltage pulse electric field technology in fruits and vegetable preservation,drying,and sterilization.On the basis of considering the phenomenon and principle of cell breakdown in fruits and vegetables caused by high-voltage pulsed electric field treatment,a cellular automaton model for fruit and vegetable breakdown in the electric field was constructed by specifying the cellular space,state,and rules.The results showed that the simulation results of the experiment were in line with the breakdown characteristics of pulsed electric field treatment of fruit and vegetable media.The fitting degree was high compared with the actual situation,and the error was small.By using cellular automaton to simulate the model of pulsed electric field treatment of fruits and vegetable media,the breakdown process of fruits and vegetable media was reflected,which was beneficial to the application and promotion of pulsed electric field technology in the field of fruits and vegetables.
