Characterization of flavor active non-volatile compounds in chicken broth and correlated contributing constituent compounds in muscle through sensory evaluation and partial least square regression analysis

The correlation between flavor-active non-volatile compounds in chicken broth, the chemical components in muscle, and sensory evaluation was analyzed through partial least square regression analysis. In chicken broth, free amino acid serine significantly and positively influenced the fatty attribute (p 10 K, Mw 5 K–10 K, Mw 0.2 K–1 K) exerted a positive influence on umami and kokumi attribute. Among nucleotides, inosine-5′-monophosphate influenced the meaty attribute, whereas guanosine-5′-monophosphate positively and significantly affected the umami attribute (p
