Abstract
Fried huajiao oil (FHO) samples prepared with red or green huajiao are widely applied in different Chinese cuisines due to their own aroma characteristics. To investigate their different aroma profiles, 2 red and 3 green FHOs were analyzed by quantitative descriptive sensory analysis (QDA) and gas chromatography-olfactometry/aroma intensity (GC-O/AI). QDA results showed a distinct difference among FHOs in terms of all sensory attributes. Thirty odorants with high OAVs and AIs were screened from 5 FHOs, among which β-myrcene, (E)-2-heptenal, limonene, α-terpineol and p-cymene were the major characteristic compounds of FHOs. In addition, through orthogonal partial least square discriminate analysis (OPLS-DA), linalool, linalyl acetate, and 1,8-cineole were considered as the volatile markers for classification of FHOs with red and green huajiao. Thereafter, aroma recombination and omission tests were performed to characterize the key aroma compounds of red and green FHOs.
