Dynamic Evolution of Volatile Aroma Compounds in Black Ginseng During Nine-Steaming and Nine-Drying Based on HS-GC-IMS and Chemometrics
Headspace–gas chromatography–ion mobility spectrometry (HS-GC-IMS) combined with chemometrics was employed to track volatile aroma compounds during the nine-steaming and nine-drying process. A total of 84 volatile signals (including monomers, dimers, and polymers) were tentatively identified, of which 73 volatile compo...
