| Research Field(Keyword & Summary) |
- Biochemical Engineering
Various biochemical reactions take place in living organisms, The key molecule of these biochemical reactions is enzyme. Enzymes generally play their physiological roles in aqueous environment. However, they exhibit unusual catalytic performances in special environments such as non-aqueous, heterogeneous, or microcompartmentalized reaction environments. In our research project, we try to develop efficient enzymatic reaction processes using non-conventional reaction environment. Resent projects included in this research topic are: (1)devolopment of novel enzyme immobilization method; (2) selective organic synthesis in non-aqueous media using lipases, (3) application of compartmentalized enzymatic reactions toward biomimetic nano/micro-bioreactors.
- Biomaterial Chemistry
Living organisms have developed sophisticated material and energy conversion systems by the combination and assembly of simple but diverse biomolecules. Understanding the
relationships between chemical properties and biological functions of biomolecules will provides useful viewpoints in material chemistry. Our research group investigates novel biomolecular-based materials including polysaccharides, proteins, and lipids. We focus on the development of novel methods for applying the molecular assembly phenomena based on colloid and interface engineering.
- Food Engineering
Japanese society is now facing the “100-year-life” time period. In recent days, the importance of meals and food has been increasing, which has resulted in diversified requirements for food functionality. The objective of our research project in food engineering field is to develop novel processing technologies for high-quality food with various additional values, including food most suitable for elderly people and functionalized nutritional food. The basic concept of this research is “Designing food functionality” based on an advanced knowledge of food chemistry and food processing technologies.
