Still more research is needed to completely understand all the effects produced by ohmic heating. The effects of the applied electric field, the incident electric current and the applied electric frequency during ohmic heating over different microorganisms and foods (at molecular and cellular level) still need to be more deeply studied. If confirmed, the electroporation effect or any other temporary permeabilization effect on cellular membranes that occurs during ohmic heating may have significant economic consequences to industry. Therefore understanding, characterizing and modeling this phenomenon is required in order to optimize and possibly exploit its effects.
