| Outline of Final Research Achievements |
The adhesion and desorption process of protein, microorganism, food soils were successfully described quantitatively by the aid of the quartz crystal microbalance based on admittance analysis. The desorption process of fat soils was also successfully described quantitatively. By using the D-factor, dynamic properties of soil layer on the surface was obtained. It was shown that the citrate treatment on stainless steel surface, which was one method to suppress protein adhesion, reduced not only adhesion amount but also adhesion rate. In addition, the possibility of differential scanning fluorimetry for investigating heat-induced protein aggregation, which affects protein adhesion process at higher temperature was also shown.
