Abstract: The structures of pomelo peel cells during extraction of natural pigment with microwave irradiation and conventional heating were investigated by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The photo- graphs showed that mechanism of microwave solid-liquid extraction was different from that of conventional heating extraction. According to these photographs, electroporation mechanism of cell wall was put forward.
