Exploring ultrasound combined with <i>Litsea pungens Hemsl</i> essential oil compound coating for modulating flavor and metabolites in Nuodeng ham: A multidimensional analysis by UHPLC-QE-MS and GC-IMS.

ABSTRACT: The mechanism of ultrasound (US) combined with Litsea pungens Hemsl essential oil (LO) compound coating on Nuodeng ham was investigated at defined power levels, including LO (0 W), L-US (low, 200 W), M-US (middle, 400 W), and H-US (high, 600 W). The differences in color, texture, volatile flavor substances, and metabolic networks among treatment groups were resolved by GC-IMS and UHPLC-QE-MS. The results indicated that both L* and a* values in the LO group were notably higher than those of the control group (CG), whereas the H-US group showed a significant reduction in hardness. The flavor analysis revealed that the compound treatment enhanced the flavor substances, including hexanal and 2-heptanone. A total of 67 differential metabolites were identified, confirming th
