(PCA) with scaling-type UV and orthogonal partial least squares–discriminant analysis (OPLS-DA). OPLS-DA, PCA, radar chart and bubble chart analyses on the sensor response values of the electronic nose and electronic tongue were used to characterize the differences in odor and taste among carp...
We also observe the sensing ability of the proposed electronic tongue under other basic taste solutions, namely: sucrose and fructose for sweet sensation, KCl for salty sensation, and caffeine for bitterness sensation and the results are shown in Figure 11f–i, respectively. The radar chart ...
