Outline of Final Research Achievements

The relationship between crude fat content and impedance in patty was analyzed using simple regression analysis: a high positive correlation was observed. This result suggested that it is possible to estimate crude fat content in patty using impedance and a regression equation based on the relationship between crude fat content and impedance in patty. It was also possible to estimate crude fat content in steak using this method.
The maximum load and load of gumminess of beef at 4 and 6 days post-mortem were significantly lower than those of beef at 2 days post-mortem. The impedance measured in a perpendicular direction to the muscle fibers of beef at 6 days post-mortem was significantly lower than that of beef at 2 days post-mortem. These results suggested that it is possible to estimate textural properties non-destructively by measuring impedance in beef.
