Results of the analysis showed significant di#erences in the quantities of taste components such as glutamic acid, taurine, potassium and ash between the Chinese chicken s and Japanese chicken s. While Chinese chicken s contained more glutamic acid, Japanese chicken s were more rich in potassium, comparatively higher in IMP as one of umami taste and amino acids which have sweet taste. Based on the taste components of the -, samples, it was found that the - stock samples fell into - distinct groups according to the principal component analysis. Moreover, it was confirmed with discriminant analysis that the - groups were discriminated based on the result of the taste component analysis, specially, in Asp, Glu,Met, Phe, His and Ca. The - groups of stocks were also discriminated by their aroma sensor patterns. It was confirmed that Chinese chicken and Japanese chicken di#er to some extent in respect to taste and aroma although both were made from similar materials. It is suggested that Chinese and Japanese di#er in their preference in taste and aroma.
