Research interests

What sort of meaning does eating have for people? As written in the afterword to The Sociology of Food by Kato Hidetoshi (Bungei Shunju, 1978), “This book is nothing more than a glimpse of the topic”. In the 30 years since it was written, this inquiry into the yet-to-be-defined is both old and new.

Food is the object of the act of eating. Food science, the basic research seeking the material properties and the mechanisms of food material, and food engineering from a practical perspective, have become academic disciplines. Many of the familiar processed foods, including frozen foods, dried foods, and instant foods, have gradually spread throughout society and become widely used because of the enormous amount of basic research conducted on heat and the mechanism of mass transfer in the processing of the food materials. Basic research will also be necessary in the future into the sharp decline in the environmental burden of food product processing, and the further improvement of food product functionality.

Meanwhile, there is a diverse academic approach to people, for whom eating is an act of self-sufficiency. These approaches include the psychological methods for quantifying the human evaluation of food and the sociological method of analyzing the mutual effect between actors on the food distribution system. These methods are useful in light of international cooperation on research based on field work. My primary laboratory is the field in Indonesia. I am enthusiastically involved with research in the environmental sector overseas that combines the perspective of agriculture and engineering with the perspective of local research and social science.

Study example

  • A comparison of the physical properties when baking bread with rice flour and rice gruel

    This shows a cross section of the bread after baking. From the left, the photos are those of bread made with wheat, bread with 15% rice flour, and bread with 15% rice gruel. The rice gruel bread at the right has the highest relative volume and it is quite soft, which is the reason for the expectations of its commercial viability.

Projections for the 21st century call for a large increase in food demand accompanying population growth, particularly in developing countries, and economic growth. Further, the penetration of the unrestricted market economy has worsened the contradictions on a global scale, such as the instability for the supply and demand markets, the expansion of the gap between the rich and the poor, and the destruction of the natural environment.
