Outline of Final Research Achievements

In recent years, the applied research of micro analysis to medical diagnosis, etc. are advancing. In this research, the electrochemical microdevice (μTAS) was developed which enables measurement of the freshness of the meat (pork) which becomes the first in the field of food analysis. The content of various nucleic acid related substances of pork were measured by μTAS developed and UPLC. As a result of comparison of K value and Ki value which are estimated by μTAS and UPLC as indexes of freshness, it was cleared that developed μTAS has a feasibility as new evaluation technology for freshness of pork meat.
