Electronic nose monitoring the red drum stored for different temperature
In the present study,an electronic nose(PEN3) was used to characterize and classify the flavor of red drum coming from different storage temperature.This method firstly sampled the flavor composition emanating from the red drum by PEN3 systems and then obtained response values of PEN3.After this,data analysis was conducted by using principal component analysis(PCA) and linear discrimination analysis(LDA).The results of this study showed that electronic nose was able to identify the fresh degrees of red fishes by LDA method.The results of this study showed that the No2 sensor signal was distinctness in the fresh degrees mensuration of red fishes by Loadings method.This new approach for red fish determinations using a portable electronic nose was faster and cheaper than classical method.
