Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 2-Ethylpyrazine, is researched, Molecular C6H8N2, CAS is 13925-00-3, about Characterization of Key Aroma Compounds in Beijing Roasted Duck by Gas Chromatography-Olfactometry-Mass Spectrometry, Odor-Activity Values, and Aroma-Recombination Experiments.COA of Formula: C6H8N2.
The dominant aroma compounds in the breast skin and breast muscle of Beijing roasted duck were investigated by gas chromatog.-olfactometry-mass spectrometry (GC-O-MS), odor-activity values, and aroma recombination. The results demonstrated that a total of 42 aroma compounds were identified in Beijing roasted duck, including aldehydes, ketones, alcs., acids, phenols, sulfur-containing compounds, and nitrogen-containing compounds Among the 42 aroma compounds, 18 were identified as important odorants with odor-activity values (OAVs) greater than 1. Aroma-recombination-omission experiments and sensory evaluation demonstrated that nine aroma compounds significantly contributed to the characteristic aroma of Beijing roasted duck. These nine key aroma compounds were 2-furfurylthiol, di-Me trisulfide, hexanal, heptanal, octanal, nonanal, methional, 1-octen-3-ol, and (E,E)-2,4-decadienal. Among these, 2-furfurylthiol (3620 ≤ OAV ≤ 31 606) and di-Me trisulfide (2515 ≤ OAV ≤ 23 470) significantly contributed to the aroma of roasted duck (p < 0.01). Sensory evaluation of the recombination model with the nine aroma compounds scored 4.5 out of 5 points. The major aroma profile of Beijing roasted duck included strong fatty, roasty, and meaty aromas. The key aroma compounds of Beijing roasted duck were concluded to be 2-furfurylthiol, di-Me trisulfide, hexanal, heptanal, octanal, nonanal, methional, 1-octen-3-ol, and (E,E)-2,4-decadienal.
