| Abstract: | "Galli Gigerii Endothelium Corneum(GGEC) is commonly used for the clinical treatment of indigestion, vomiting, diarrhea, and infantile malnutrition with accumulation. In recent decades, omnivorous domestic chickens, the original source of GGEC, has been replaced by broilers, which may lead to significant changes in the quality of the yielding GGEC. Through subjective and objective sensory evaluation, biological evaluation, and chemical analysis, this study compared the odor and quality between GGEC derived from domestic chickens and that from broilers. The odor intensity between them was compared by odor profile analysis and it was found that the fishy odor of GGEC derived from domestic chickens was significantly weaker than that of GGEC from broilers. Headspace-solid phase microextraction-gas chromatography-triple quadrupole tandem mass spectrometry(HS-SPME/GC-QQQ-MS/MS) suggested that the overall odor-causing chemicals were consistent with the fishy odor-causing chemicals. According to the odor activity va-lue and the orthogonal partial least squares discriminant analysis(OPLS-DA) result, dimethyl trisulfide, 2-methoxy-3-isobutylpyrazine, and 2-methylisoborneol were responsible for the fishy odor(OAV>/=1) and the content of fishy odor-causing chemicals in GGEC derived from broilers was 1.12-2.13 folds that in GGEC from domestic chickens. The average pepsin potency in GGEC derived from broilers was 15.679 U.mg~(-1), and the corresponding figure for the medicinal from domestic chickens was 26.529 U.mg~(-1). The results of pre-column derivatization reverse-phase high-performance liquid chromatography(RP-HPLC) assay showed that the content of total amino acids and digestion-promoting amino acids in domestic chickens-derived GGEC was 1.12 times and 1.15 times that in GGEC from broilers, and the bitter amino acid content was 1.21 times folds that of the latter. In conclusion, GGEC derived from domestic chickens had weaker fishy odor, stronger enzyme activity, higher content of digestion-promoting amino acids, and stronger bitter taste than GGEC from broilers. This study lays a scientific basis for studying the quality variation of GGEC and provides a method for identifying high-quality GGEC. Therefore, it is of great significance for the development and cultivation of GGEC as both food and medicine and breeding of corresponding varieties" |
