Since the Tohoku earthquake, there is much interest in processed foods, which can be stored for long periods at
room temperature. Retort heating is one of the main technologies employed for producing it. We developed the
innovative food processing technology, which supersede retort, using ohmic heating and aseptic packaging.
Electrical heating involves the application of alternating voltage to food. Compared with retort heating, which
uses a heat transfer medium, ohmic heating allows for high heating efficiency and rapid heating. In this paper
we ohmically heated chicken breast samples and conducted various tests on the heated samples. The
measurement results of water content, IMP, and glutamic acid suggest that the quality of the ohmically heated
samples was similar or superior to that of the retort-heated samples. Furthermore, based on the monitoring of
these samples, it was observed that sample quality did not deteriorate during storage.
