Their quality attributes and volatile flavor compounds were then analyzed. The results showed that as the moisture content of the semi-dried dumplings decreased, the total peak area in low-field nuclear magnetic resonance (LF-NMR) analysis significantly decreased, and water transitioned from high to low degrees of freedom. Moderate dehydration improved the whiteness of the dumplings, with the whiteness of the 350 g/kg (w.b.) sample (81.12) being 13.19% higher than that of the fresh sample (71.67). The hardness of the semi-dried dumplings increased as the moisture content decreased, while their rehydration ratio decreased. Gas chromatography-mass spectrometry (GC-MS) analysis detected 50 volatile compounds in the dumpling wrapper and 62 in the filling. Among these, total of 19 and 25 key volatile compounds were identified in the wrapper and filling, respectively.

This study investigated the apparent thermal inactivation behavior of <em>C. jejuni</em> NCTC 11168 on intact chicken carcasses subjected to water-bath cooking (60-100 °C). Bacterial survival was evaluated at multiple time points across different anatomical regions of the carcass.

Statistically significant differences in apparent inactivation rates were observed among anatomical regions (<em>P < 0.05</em>). However, the magnitude of these differences was limited. These variations are likely attributable to differences in carcass structure and localized heat transfer rather than intrinsic differences in bacterial heat resistance.
