Discriminative analysis of aroma profiles in diverse cigar products varieties through integrated sensory evaluation, GC-IMS and E-nose. J Chromatogr A 2024; 1733:465241. [PMID: 39153428 DOI: 10.1016/j.chroma.2024.465241] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2024] [Revised: 07/13/2024] [Accepted: 08/06/2024] [Indexed: 08/19/2024]
Abstract
Cigars, treasured for their rich aromatic profiles, occupy a notable segment in the global consumer market. The objective of this study was to characterize the volatile aroma compounds that shape the flavor profiles of six distinct varieties of Great Wall cigars, contributing to the understanding of cigar aroma analysis. Utilizing HS-GC-IMS and sensory evaluation, the study discerned the aroma profiles of GJ No. 6 (GJ), Animal from the Chinese zodiac (SX), Range Rover No. 3 Classic (JD), Miracle 132 (QJ), Sheng Shi No. 5 (SS), and Red 132 (HS) cigars. The analysis uncovered a spectrum of characteristic aromas, including tobacco, creaminess, cocoa, leather, baking, herbaceous, leathery, woodsy, and fruity notes. A total of 88 compounds were identified, categorized into 11 chemical classes, with their quantities varying among the cigars in a descending order of QJ, JD, GJ, SS, HS, and SX. 24 compounds, such as 2-heptanone, n-butanol, 2,6-dimethylpyrazine and 2-furfuryl methyl sulfide were considered as key differential components. The volatile components were effectively differentiated using principal component analysis (PCA), orthogonal partial least squares-discriminant analysis (OPLS-DA), and cluster analysis, revealing correlations between sensory attributes, key components, and electronic nose (E-nose). This research introduces a novel method for analyzing volatile aroma components in cigars, offering insights to enhance cigar quality and to foster the development of new products with unique aroma profiles.

[PMID: 38401171 PMCID: PMC11339174 DOI: 10.1093/ntr/ntae039] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2023] [Revised: 02/12/2024] [Accepted: 02/19/2024] [Indexed: 02/26/2024]
Abstract
INTRODUCTION To identify how flavor is conceptualized with respect to cigarillos to illuminate areas of concordance and discordance and provide a pathway for the harmonization of tobacco flavor measurement. AIMS AND METHODS Three methods were used to identify research measuring flavors respective to cigarillo products including: (1) querying research databases using key words "cigarillo," "tobacco" and "flavor"/'flavour,' (2) sub-sampling of the eligible literature with backward and forward reference searching, and (3) a bibliographic search of key experts. Two reviewers independently screened titles, abstracts, and full texts. Inclusion criteria required manuscripts to be available in English, published prior to 3/1/2022, be original and peer-reviewed, and include a measure of flavor pertaining to cigarillo products. A total of 163 manuscripts met these criteria and were subsequently evaluated. RESULTS Cigarillo flavor determinations were made based on the presence of flavoring agents, sensory characteristics, marketing or package characteristics, pre-defined lists, the absence of any of these, and/or were undefined. Individual flavors and their related classifications were not altogether mutually exclusive due to differences in conceptualization which has evolved over time. CONCLUSIONS Flavor measures continue to evolve, likely in response to both tobacco control policies and industry shifts. There is a lack of standardization in flavor conceptualization that can be ameliorated through intentional integration of multiple forms of research such as identifying patterns of flavoring agents and/or marketing strategies that elicit a specific flavor profile. By doing this, we may more comprehensively evaluate the impact of flavors, their constituents, and related marketing strategies on broader population health. IMPLICATIONS There are discrepancies in the conceptualization of flavor in tobacco and nicotine products. The lack of standardized, definitive language limits our ability to comprehensively evaluate the population-level health impact of flavors in addition to our ability to effectively inform, implement, and enforce policies restricting flavors in tobacco and nicotine products.

Abstract
This study assessed the hypothetical impact of flavored cigar sales restrictions on cigar smoking among Black young adult cigar smokers (ages 21-29). Forty in-depth interviews were conducted in 2020. Interviews were independently coded and analyzed using thematic analysis. When asked how they would smoke cigars given a flavor sales restriction, half of participants reported they would smoke in the same way, a third would stop or reduce smoking, and a few were unsure of what they would do. Cigar smoking outcome expectancies, preference for flavors, and perceived addictiveness of cigar products may predict cigar smoking change given flavor sales restrictions.

Abstract
OBJECTIVE This study aimed to provide an inventory of different types of flavour accessories for combustible tobacco products in eight countries varying in their approaches to flavour legislation and cultural aspects, including tobacco use. METHODS A standardised search protocol was developed and shared with local informants to acquire information on the availability and marketing of flavour accessories in web shops accessible from Brazil, India, Italy, Singapore, South Africa, Switzerland, the UK and the USA. Characteristics of the products and web shops were reported, and flavours were categorised in a flavour wheel. RESULTS Flavour accessories were available in all participating countries. Reported types are flavour capsules, cards, filter tips and tubes for make-your-own cigarettes, drops, sprays, rolling paper, aroma markers, a flavour stone and a flavour powder. In total, 118 unique flavours were reported, which were mostly fruity and sweet. Marketing of these products was often associated with (menthol) flavour bans. CONCLUSIONS The wide availability and variety of flavour accessories raise significant public health concerns, as they have attractive flavours, and thus hinder the regulatory aim of flavour bans. Flavour accessories are not tobacco products and thus not regulated as such. Therefore, it is recommended that policymakers include these products in comprehensive flavour bans, to close this loophole in existing tobacco control measures.

Abstract
ObjectivesFlavoured products are especially appealing to youth and contribute to the onset of waterpipe smoking and continued use of waterpipe tobacco. The goal of database and chemical analysis was to provide a clear overview of commonly used flavours and flavourings in tobacco and related waterpipe products, that is, herbal molasses and steam stones. METHODS In 2019, 249 waterpipe tobacco products were registered in the European Common Entry Gate by manufacturers to be marketed in The Netherlands. Flavour categories were assigned to the registered products based on their brand names and product descriptions. Nicotine and eleven 1111 flavourings were identified and quantified in waterpipe tobacco (n=8), herbal molasses (n=7) and steam stones (n=4) by extraction and gas chromatography-mass spectrometry (GC-MS) analysis. RESULTS Flavour categories could be assigned to 237 of 249 registered waterpipe tobacco products. Eight flavour main categories and 48 unique subcategories were identified and presented in a flavour wheel. All registered waterpipe tobacco products were flavoured, and the majority (78%) was fruit flavoured. Herbal molasses contained similar median flavouring levels, and steam stones contained lower median levels compared with waterpipe tobacco. Flavourings in waterpipe products were almost exclusively fruity and sweet, often in combination with menthol/mint flavourings. CONCLUSIONS This study is the first to present a waterpipe tobacco flavour wheel, providing a quick overview of waterpipe tobacco flavours and thereby aiding communication among experts around the globe. GC-MS analysis revealed that the most prevalent flavourings are present in similar levels in herbal and tobacco waterpipe products. Banning flavourings in all waterpipe products would be a good strategy to reduce waterpipe smoking among youth.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2023; 20:5086. [PMID: 36981995 PMCID: PMC10049274 DOI: 10.3390/ijerph20065086] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/09/2023] [Revised: 03/01/2023] [Accepted: 03/09/2023] [Indexed: 06/18/2023]
Abstract
While the US Food and Drug Administration (FDA)'s proposal to reduce the nicotine content in cigarettes is gaining traction, it is still undetermined whether the policy will also include other combustible tobacco products, such as little cigars and cigarillos (LCCs), and how such a policy should be communicated given the patterns of use and perceptions around LCCs. This study examined perceptions of nicotine and addiction related to LCC use and involved data collection from eight semi-structured virtual focus groups conducted in Summer 2021 in the US. Participants were adults who reported past-30-day use of LCCs, consisting of African American males (n = 9), African American females (n = 9), white males (n = 14), and white females (n = 11). Participants discussed their perceptions of nicotine and addiction in general and in relation to LCC use. Inductive thematic analysis of transcripts was conducted. Differences across race and sex groups were examined. Participants did not consider nicotine to be a characterizing feature of LCCs; rather, they generally associated nicotine with cigarettes. Participants' views of nicotine and addiction related to LCCs were discussed along four dimensions: context of use, frequency of use, the presence of cravings, and whether a product is modified (e.g., by adding marijuana). Social and infrequent use, a lack of cravings, and the use of LCCs for marijuana were considered indicative of a lack of addiction and reasons not to be concerned about nicotine in LCCs. Because perceptions of nicotine and addiction related to LCCs differ from those of cigarettes, communications about a reduced nicotine policy that includes LCCs should consider these differences to ensure the policy is understood by people who currently use LCCs and to prevent people who use cigarettes from switching to LCCs.

Abstract
Flavored cigar sales restrictions (FCSRs) may reduce cigar smoking and protect public health. This study examined the correlates of behavior change intents in response to a hypothetical FCSR. Data were from a nationally representative sample of adult flavored cigar smokers (ages ≥21; n = 343) collected through an online survey in 2021. Respondents selected their behavior change intents in response to a hypothetical FCSR, including (1) quitting cigars altogether; (2) smoking plain or non-flavored cigars; (3) smoking other flavored tobacco products; (4) smoking cannabis; and (5) other options. Weighted logistic regressions were used to examine the associations of socio-demographic backgrounds, tobacco use history, and tobacco dependence with behavioral change intents. In response to an FCSR, 15.1% of respondents would quit smoking cigars altogether, 41.6% would smoke plain cigars without flavors, 33.4% would substitute flavored cigars with other flavored tobacco products, and 29.2% would substitute flavored cigars with cannabis. Large cigar smokers and blunt smokers were less likely to quit cigars altogether than non-smokers of those products; females and racial/ethnic minorities were more likely to substitute flavored cigars with other flavored tobacco and cannabis products, respectively, than males and non-Hispanic White respondents. Results suggest that FCSRs may reduce cigar smoking among a portion of U.S. flavored cigar smokers while leaving more continuing to smoke plain cigars or transitioning to use other flavored tobacco products or cannabis. Implementing FCSRs should be accompanied by comprehensive flavored tobacco sales restrictions, cessation programs, and educational messages aimed at reducing the use of cigars and other substances.

Dissonance in Young Adult Cigarillo Users' Categorization of Concept Flavored and Unflavored Products. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:7219. [PMID: 35742467 PMCID: PMC9223595 DOI: 10.3390/ijerph19127219] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/11/2022] [Revised: 06/01/2022] [Accepted: 06/08/2022] [Indexed: 01/27/2023]
Abstract
This study asks young adult cigarillo users to categorize their preferred flavor in order to examine user consensus and potential methodological and regulatory implications of flavor name-based categorization systems. Young adult (21-28 years) cigarillo users (n = 426) named and categorized their favorite cigarillo flavor into one of seven categories: Fruit, Sweet and Candy, Mint, Alcohol, Menthol, Tobacco, and Other. Flavor responses were coded as characterizing (ex: Grape, Wine) or concept (ex: Jazz, Diamond) flavors. Variation within and between categories was assessed, including the presence of concept flavors and the placement of flavors in multiple categories. Of the 66 unique flavor names provided, participants placed 20 (30.1%) in more than one flavor category. Most of the Tobacco (76.9%) and Other (69.2%) flavor names appeared in multiple categories. The majority of flavor names in the Tobacco (69.2%) and Other (61.5%) categories were concept flavors. Concept flavors were placed in multiple categories (45.0%) twice as often as characterizing flavors (23.9%). This study has identified dissonance among cigarillo users' flavor categorizations, particularly for concept flavored and unflavored products. Flavor names may obscure how and whether a product is flavored. Research on and regulation of flavored tobacco products should classify products by flavor additives rather than by name alone.

Behavioral economic assessment of abuse liability for Black & Mild cigar flavors among young adults. Exp Clin Psychopharmacol 2022; 30:113-119.

Abstract
Cigars are available in a variety of flavors that may impact uptake and use, but little is known about how different flavors affect abuse liability. This study used 3 behavioral economic tasks to examine abuse liability of Black & Mild cigars differing in flavor among young adult cigarette smokers. Participants were 25 cigar-naïve young adults (aged 18-25 years) who smoked ≥ 5 cigarettes/day. In 5 Latin square-ordered laboratory visits, participants completed 3 abuse liability tasks (drug purchase task, cross-price purchase task, and multiple-choice procedure) for each of 4 cigar flavors (original, cream, wine, or apple) and own-brand cigarettes. In the drug purchase task, relative to own-brand cigarettes, all cigar flavors were associated with lower abuse liability using most measures (intensity, breakpoint, maximum total tobacco expenditure for 1 day [ps < .05]), although only wine-flavored cigars scored significantly lower using 1 measure (price at maximum total tobacco expenditure for 1 day). When cigars and cigarettes were available concurrently in the cross-price purchase task, all cigar flavors functioned as substitutes for cigarettes. Using the multiple-choice procedure, crossover points for wine- (mean = $0.61) and apple-flavored cigars (mean = $0.71) were significantly lower than own-brand cigarettes (mean = $0.86) and original-flavored cigars (mean = $1.00); no significant differences existed between own-brand cigarettes and original-flavored cigars. Thus, whereas abuse liability may be highest for participants' own-brand cigarette, young adult smokers may be willing to use flavored cigars. Furthermore, abuse liability varies by cigar flavor, with original- and cream-flavored cigars appearing to have the highest abuse liability. Characterizing flavors and flavor additives in cigars represent an important tobacco regulatory target. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Yogeswaran S, Muthumalage T, Rahman I. Comparative Reactive Oxygen Species (ROS) Content among Various Flavored Disposable Vape Bars, including Cool (Iced) Flavored Bars. TOXICS 2021; 9:235. [PMID: 34678931 PMCID: PMC8538728 DOI: 10.3390/toxics9100235] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/03/2021] [Revised: 09/13/2021] [Accepted: 09/16/2021] [Indexed: 11/16/2022]
Abstract
Studies have shown that aerosols generated from flavored e-cigarettes contain Reactive Oxygen Species (ROS), promoting oxidative stress-induced damage within pulmonary cells. Our lab investigated the ROS content of e-cigarette vapor generated from disposable flavored e-cigarettes (vape bars) with and without nicotine. Specifically, we analyzed vape bars belonging to multiple flavor categories (Tobacco, Minty Fruit, Fruity, Minty/Cool (Iced), Desserts, and Drinks/Beverages) manufactured by various vendors and of different nicotine concentrations (0-6.8%). Aerosols from these vape bars were generated via a single puff aerosol generator; these aerosols were then individually bubbled through a fluorogenic solution to semi-quantify ROS generated by these bars in H2O2 equivalents. We compared the ROS levels generated by each vape bar as an indirect determinant of their potential to induce oxidative stress. Our results showed that ROS concentration (μM) within aerosols produced from these vape bars varied significantly among different flavored vape bars and identically flavored vape bars with varying nicotine concentrations. Furthermore, our results suggest that flavoring chemicals and nicotine play a differential role in generating ROS production in vape bar aerosols. Our study provides insight into the differential health effects of flavored vape bars, in particular cool (iced) flavors, and the need for their regulation.

PLoS One 2021; 16:e0254537. [PMID: 34242367 PMCID: PMC8270437 DOI: 10.1371/journal.pone.0254537] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2021] [Accepted: 06/28/2021] [Indexed: 11/18/2022] Open
Abstract
Although the global tobacco market of cigarillos is substantial, little is known about their particulate matter (PM) emissions. For exposure risk assessment of cigarillos, the PM fractions PM10, PM2.5, and PM1 of eight cigarillo brands (four with filters) and a reference cigarette were measured. For this purpose, second-hand smoke was generated by an automatic smoke pump in a measuring chamber with a volume of 2.88 m³. The mean particle concentrations of the cigarillos ranged from 2783 μg/m³ to 6686 μg/m³ for PM10, from 2767 μg/m³ to 6585 μg/m³ for PM2.5, and from 2441 to 4680 μg/m³ for PM1. Mean concentrations of the reference cigarette for PM10, PM2.5, and PM1 were 4400 μg/m³, 4335 μg/m³, and 3289 μg/m³, respectively. Filter-tipped cigarillos showed between 5% and 38% lower PM10 and PM2.5 levels, respectively, and between 4% and 30% lower PM1 levels. Our findings show generally high PM emissions for all investigated tobacco products. Therefore, the declaration of PM amounts to government authorities should be mandatory for all tobacco products. Policymakers should ensure that corresponding information will be provided in the future.

E-cigarette-induced pulmonary inflammation and dysregulated repair are mediated by nAChR α7 receptor: role of nAChR α7 in SARS-CoV-2 Covid-19 ACE2 receptor regulation. Respir Res 2020; 21:154. [PMID: 32552811 PMCID: PMC7301079 DOI: 10.1186/s12931-020-01396-y] [Citation(s) in RCA: 58] [Impact Index Per Article: 14.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2020] [Accepted: 05/14/2020] [Indexed: 12/13/2022] Open
Abstract
Electronic cigarette (e-cig) vaping is increasing rapidly in the United States, as e-cigs are considered less harmful than combustible cigarettes. However, limited research has been conducted to understand the possible mechanisms that mediate toxicity and pulmonary health effects of e-cigs. We hypothesized that sub-chronic e-cig exposure induces inflammatory response and dysregulated repair/extracellular matrix (ECM) remodeling, which occur through the α7 nicotinic acetylcholine receptor (nAChRα7). Adult wild-type (WT), nAChRα7 knockout (KO), and lung epithelial cell-specific KO (nAChRα7 CreCC10) mice were exposed to e-cig aerosol containing propylene glycol (PG) with or without nicotine. Bronchoalveolar lavage fluids (BALF) and lung tissues were collected to determine e-cig induced inflammatory response and ECM remodeling, respectively. Sub-chronic e-cig exposure with nicotine increased inflammatory cellular influx of macrophages and T-lymphocytes including increased pro-inflammatory cytokines in BALF and increased SARS-Cov-2 Covid-19 ACE2 receptor, whereas nAChRα7 KO mice show reduced inflammatory responses associated with decreased ACE2 receptor. Interestingly, matrix metalloproteinases (MMPs), such as MMP2, MMP8 and MMP9, were altered both at the protein and mRNA transcript levels in female and male KO mice, but WT mice exposed to PG alone showed a sex-dependent phenotype. Moreover, MMP12 was increased significantly in male mice exposed to PG with or without nicotine in a nAChRα7-dependent manner. Additionally, sub-chronic e-cig exposure with or without nicotine altered the abundance of ECM proteins, such as collagen and fibronectin, significantly in a sex-dependent manner, but without the direct role of nAChRα7 gene. Overall, sub-chronic e-cig exposure with or without nicotine affected lung inflammation and repair responses/ECM remodeling, which were mediated by nAChRα7 in a sex-dependent manner.
