Agricultural Food Engineering Lab
Machine-translated · View original
A lab that studies how food changes from cooking and processing through to digestion.

AboutAbout the lab
Tracing how food changes on its way to being eaten
The Agricultural Food Engineering Lab studies how food materials change from cooking and processing through to eating and digestion.
The lab feeds these findings back into its work and also examines how to optimize the conditions of each operation.
In particular, it works on how plant-based foods are digested, using in vitro digestion methods, and on ways to maintain the quality of fresh-cut produce.
Both lines of research are carried out in collaboration with research institutions in Japan and abroad.
Key terms
- In vitro digestion method
- A method of studying how food is digested by creating conditions outside the body that imitate the action of digestion
- Fresh-cut produce
- Vegetables or fruits that have been cut or peeled so they are ready to use, such as cut vegetables
- Low oxygen
- A state with less oxygen than in air. When harvested produce is stored under this condition, its respiratory metabolism decreases
ResearchResearch themes
The lab studies the changes that occur in food materials throughout the whole process from cooking and processing to eating and digestion. It currently focuses on the digestive properties of plant-based foods and on maintaining the quality of fresh-cut produce.
*Illustrative imageHow plant-based foods are digested
Cooking and processing change how easily food is digested, as the difference between cooked white rice and rice porridge shows, but the detailed mechanisms are not well understood. Focusing on the properties of plant cells, the lab uses in vitro digestion methods to investigate, for example, the relationship between fine structural changes in rice grains during cooking and their digestibility.
*Illustrative imageKeeping cut vegetables fresh
When harvested produce is stored under low-oxygen conditions, respiratory metabolism slows and quality is maintained. Aiming to develop techniques for preserving fresh-cut vegetables for longer by actively controlling environmental conditions such as gas and light, the lab conducts long-term storage experiments using bell peppers.
