Song, Xuebo published the artcileCharacterization of key aroma-active sulfur-containing compounds in Chinese Laobaigan Baijiu by gas chromatography-olfactometry and comprehensive two-dimensional gas chromatography coupled with sulfur chemiluminescence detection, HPLC of Formula: 14667-55-1, the main research area is Baijiu aroma gas chromatog olfactometry; 2-Furfurylthiol; 2-Furfurylthiol, (PubChem CID: 7363); 2-Methyl-3-furanthiol; 2-Methyl-3-furanthiol, (PubChem CID: 34286); AEDA; Baijiu; Benzenemethanethiol; Benzenemethanethiol, (PubChem CID: 7509); Dimethyl disulfide, (PubChem CID: 12232); Dimethyl trisulfide, (PubChem CID: 19310); GC × GC; Methional, (PubChem CID: 18635); Sulfur chemiluminescence detection.
Volatile sulfur-containing compounds (VSCs) often exist at extremely low concentrations, making them difficult to be determined The VSCs in Laobaigan (LBG) Baijiu were analyzed by headspace solid-phase microextraction (HS-SPME) coupled with GC × GC-SCD, by which 12 VSCs were identified. Among the 65 odor-active compounds that were determined by GC-O with the aid of aroma extract dilution anal. (AEDA), benzenemethanethiol and 2-methyl-3-furanthiol were found to possess the highest FD values of 6561. The limits of detection (LODs) of the identified VSCs determined by GC × GC-SCD were found to be extremely low at 0.05-1.53 ng/L, with their anal. recoveries from 85% to 116%. The VSCs in the LBG samples were determined in a range of concentrations from 0.77 ± 0.02 μg/L to 60.04 ± 2.32 μg/L. Benzenemethanethiol, di-Me trisulfide, 2-methyl-3-furanthiol and 2-furfurylthiol exhibited odor activity values (OAVs) > 100 and significantly contributed to the overall aroma of LBG Baijiu.
