Comparison of quality and sensory attributes for new crossbred and commercial Korean native chicken

The objective of this study was to evalutate and compare quality and sensory attributes of commercial (Control) and new crossbred (NC) Korean native chicken. Control (60 birds) and 180 NC (A, B, and C) were raised under the same environmental condition. After slaughtering, analyses of carcass ratio (%), nucleotides (㎎/100 g), and descriptive sensory evaluation were performed. On carcass ratio, there were no differences found by breed and sex except for C. Male of C had lower carcass rate than that of Control (P＜0.05). Male of NC had higher AMP and IMP contents than those of Control (P＜0.05). B had higher inosine content than Control. B and C had similar or lower inosine and hypoxanthine than Control. A, B, and C had similar or lower hypoxanthine content than Control. Total nucleotide contents were higher in NC than Control in male. However, in female, A had lower AMP and inosine content than Control. In descriptive analysis, male of B had stronger flavor than Control. Male of A had tenderer than Control. Overall acceptance of A and B was higher than Control. By the results, in male, A and B may be superior to control from higher carcass ratio, AMP, IMP contents, and higher overall acceptance in sensory.
