Herein, the pyrolysis characteristics of three types of tobacco (oriental tobacco, burley tobacco and flue-cured tobacco) were studied by using thermogravimetric technique combined with thermal analysis kinetics method. The weight loss processes of each tobacco sample can be divided into four stages, namely dehydration, decomposition of volatile components, decomposition of hemicellulose and cellulose, and decomposition of lignin and carbonisation. Different types of tobacco exhibited various pyrolysis characteristic parameters in terms of T_i, T_f, DTG_max, and CPI, indicating an obvious difference in the thermal decomposition characteristics of tobacco. And then a stepwise heating strategy was designed to in-depth investigate the pyrolysis characteristics and release behaviour of aroma components at different thermal weight loss stages by using the self-built infrared tube furnace combined with Cambridge filter capture system. The weight loss stages II and III would generate most of the aroma components for each type of tobacco. The release amount of oxygen heterocyclic and ketone compounds exhibited the order of flue-cured tobacco (558.90 μg·g⁻¹) &gt; burley tobacco (423.44 μg·g⁻¹) &gt; oriental tobacco (291.55 μg·g⁻¹) during the four stages. The release amount of nitrogen heterocyclic compounds exhibited the order of burley tobacco&gt;flue-cured tobacco&gt;oriental tobacco, while the organic acids exhibited the opposite order. Furthermore, the physicochemical properties of biochar generated from different types of tobacco were characterised and compared by elemental analysis, Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). This study may provide guidelines for the rational utilisation of different types of tobacco leaves in related products.</p>\u0000 </div>","PeriodicalId":170,"journal":{"name":"Flavour and Fragrance Journal","volume":"40 3","pages":"512-527"},"PeriodicalIF":2.1,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143831049","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, drying technology plays a significant role in aroma quality. To reflect the volatile differences and the dynamic change of volatile profiles of dried lemon peel as affected by drying methods, the volatile compounds of dried peel prepared under three drying methods were analysed by gas chromatography–mass spectrometry combined with chemometrics. According to the results, drying at 35°C allowed to obtain peels with high titratable acidity, high flavonoid content and high antioxidant activity. On the other hand, vacuum freeze drying allowed to obtain samples with high total soluble solids and highest polyphenol contents. Eight volatile compounds were identified, with beta-and alpha-pinene and limonene found to play an important role in the discrimination of the different drying processes, based on variable importance in projection ≥ 1.2. These substances might be responsible for what caused the significant flavour difference between differently dried peel flours. The combination of HS–GC–MS and chemometrics offers a valuable tool for the identification of type-specific volatile markers in lemon peels.

This research focused on the fabrication of inclusion complexes through co-precipitation and response surface optimization, employing Fenugreek polysaccharide (FP15) as the wall material. The complexes were assessed through thermal analysis and in vitro slow-release investigations. XRD, FTIR and SEM analysis proved that LEO formed supramolecular structure with FP15 through hydrogen bonding and van der Waals force, and was successfully embedded with packaging efficiency of 57.33%. Thermal behaviour analysis showed that FP15 as a wall material significantly improved the thermal stability of LEO. The analysis based on the KAS and Coats-Redfern methods showed that the apparent activation energy of inclusion compounds increased with the increase of conversion rate, and the secondary reaction model (F2) could better describe the pyrolysis reaction mechanism of inclusion compounds. In vitro release experiments showed that the release of LEO from the inclusion at 37°C (human body temperature) and 65°C (food processing temperature) followed a first-order kinetic model, with LEO being released from the carrier by non-Fickian diffusion. The analysis of pyrolysis products showed that the inclusion compound pyrolyzed at 300°C, 600°C and 900°C to produce a large number of aldehydes, esters and non-/semi-volatile organic acids. The production of these flavour substances improves the quality, concentration of aroma, rich-ness and harmony of the cigarette during smoking. In summary, FP15 as a wall material slowed down the release of LEO, enhanced its stability and improved the sensory quality of cigarettes.</p>\u0000 </div>","PeriodicalId":170,"journal":{"name":"Flavour and Fragrance Journal","volume":"40 3","pages":"582-596"},"PeriodicalIF":2.1,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143831056","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, exogenous ATP also significantly enhanced the content of the titratable acidity (TA) of grape fruits after harvest. This was reflected by the observations that ATP treatment increased the hardness, TSS content, vitamin C content and soluble protein content of the harvested grape fruits by 14.39%, 6.29%, 31.05% and 15.18% on average during 8 days of storage, respectively, compared to the controls. In addition, the harvested grape fruits treated with exogenous ATP had higher activities of SOD (superoxide dismutase) and CAT (catalase) and higher contents of total phenolics and flavonoids compared to the controls.

Some studies have reported pharmacological activities such as antitumor, antinociceptive, anti-inflammatory and neuroprotective activities. This study aimed to investigate the spasmolytic, antitussive, expectorant and anti-asthmatic effects of vanillin in rodents. The spasmolytic activity of vanillin was assayed in isolated rat tracheas that were contracted with carbachol or KCl. The in vivo effects were evaluated in mouse models of citric acid-induced cough, phenol red dosage in bronchoalveolar lavage and ovalbumin-induced asthma. The maximal relaxing effect promoted by vanillin in isolated rat trachea was greater in contractions induced by KCl 60 mM than by carbachol (10 μM). In calcium-free media, this effect was significantly reduced during CCh-induced contractions. Vanillin at doses of 10, 30 or 100 mg/kg reduced the number of inflammatory cells in bronchoalveolar lavage and the number of coughs in mice after treatment. The effect of vanillin may be related to the opioid receptor, as the antitussive effect was abolished in the presence of 0, 4 mg/kg naloxone. The vanillin-loaded nanoemulsions exhibited expectorant activity.
