“…Five types of ketones were identified in the Cuiguan pears from the four different areas, which usually have a long-lasting floral scent [ 21 ]. Terpene compounds are important components of a fruit’s aroma, giving the fruit a floral aroma [ 28 ]. In this study, two terpenes were identified; beta-pinene had a resin-like aroma and thiophene was similar to a citrus and lemon aroma.…”

“…Volatile organic compounds (VOCs) of the Cuiguan pears were analyzed by HS-GC-IMS, according to [ 28 ] with a little modification. It was composed of an Agilent 490 gas chromatograph (Agilent Technologies, Palo Alto, CA, USA) and an IMS instrument (FlavourSpec ® , Gesellschaft für Analytische Sensorsysteme mbH, Dortmund, Germany) that was equipped with a PAL3 automatic sampler (CTC Analytics AG Company, Basel, Switzerland).…”

The Cuiguan pear is called “June snow” and the skin is thin; the meat is crisp and juicy; the taste is thick and fresh; and the juice is rich and sweet. In this study, the volatile organic compounds and the sensory and physicochemical parameters of the Cuiguan pear from four different regions of China (Sichuan (SC), Shangdong (SD), Chongming (CM), Zhuanghang (ZH)) were assessed. The highest differences in the physicochemical parameters were observed between four regions. The volatile fingerprints of GC-IMS showed great differences in the volatile of the Cuiguan pear, which suggested that the aroma of pears could be largely impacted by origin areas. (E)-ethyl-2-hexenoate can be used to distinguish between the ‘CM’ and pears from other regions. High contents of 2-heptanone, 1-pentanol, 1-butanol, 3-methylbutanol, butyl 2-methylbutanoate, heptyl acetate and butyl acetate were observed in the ‘SD’. Dimethyl trisulfide, 6-methyl-5-hepten-2-one, 3-hydroxy-2-butanone, 1-penten-3-one, beta-pinene, γ-terpinene, propanal, (e)-2-pentenal, (e)-2-heptenal, 1-pentanol and 3-methyl-1-pentanol were primarily contained in the ‘ZH’. Principal component analysis showed that there was very good discrimination based on the information obtained from GC-IMS for four samples. These findings were in agreement with the sensory analysis. In the opinion of the respondents to the consumer test, ‘ZH’ resulted in the most appreciated sample based on the average scores of the acceptability. This study provides some reference for the development and utilization of the Cuiguan pear.

“…It is worth noting that aldehydes have a low threshold and emit a grassy odor at low concentrations, transitioning to a strong aroma of nuts and fats at higher concentrations. 40,41 On the other hand, the relative contents of alcohols varied signicantly among the six types of garlic samples, with G3 displaying the highest relative content at 26.50% and G1 the lowest at 9.91%. Additionally, esters contribute to the oral and fruity fragrance, and their relative contents also exhibited signicant differences between samples, with G3 having the highest relative content of 5.03% and G1 having the lowest at 0.47%.…”

“…Gas chromatography–ion mobility spectrometry (GC–IMS) is a detection technology that combines the high separation ability of GC and the rapid response of IMS. , The technique boasts high sensitivity and accuracy, detects samples with low concentrations, does not require sample pretreatment, and retains the original flavor of the sample to the maximum extent. It is a new method to characterize the flavor or detect VFCs in agricultural products to identify different regions from which they originate. , The difference in the Molixiang table grapes grown in different geographical regions of China was distinguished accurately by a combination of GC–IMS and principal component analysis (PCA) . GC–IMS and statistical methods were used to identify fu brick tea, white tea, and oolong tea from different regions.…”

Although cigar tobacco leaves (CTLs) have a high economic value, research regarding the flavor characteristics of CTLs is currently limited. A comprehensive study of the flavor characteristics of CTLs from different regions of China was conducted by identifying their volatile-flavor-containing compounds (VFCs) and flavors. The samples were analyzed via gas chromatography−ion mobility spectrometry (GC−IMS) and sensory evaluation. Results revealed considerable differences in the VFC contents of CTLs from different regions of China, suggesting that the VFLs of CTLs could be influenced by geographical origin. Mainly, phenols, pyrazines, and aldehydes were present in the CTLs from Sichuan. High contents of esters and pyrazines were present in the CTLs from Hubei, while esters were the major components of the CTLs from Hainan. Multivariate analysis results showed the effective differentiation of samples from different geographical origins based on the GC−IMS results. Sensory evaluation revealed that the flavors of CTLs from different geographical origins were different. 1,8-Pinene, 3-methyl-3-butene-1-ol, 2,3-dimethyl-5-ethylpyrazine, 4-methyl-3-penten-2-one, and (E)-2-pentenal might serve as geographical marker compounds, indicating the geographical origin of CTLs based on the results of GC−IMS and sensory evaluation. This study may be beneficial for the trade of CTLs and the development of cigar products.
