AbstractThis article provides a critical overview of current methods to quantify essential oil components. The fields of application and limits of the most popular approaches, in particular relative percentage abundance, normalized percentage abundance, concentration and true amount determination via calibration curves, are discussed in detail. A specific paragraph...... hiện toàn bộ
AbstractAroma extract dilution analysis (AEDA) of the volatile fractions of green and black tea samples revealed 28 odourants of which 27 were identified. As the odour quality and the chromatographic properties of most of the odourants occurring in the air above the tea powders agreed with those which were identified by the preceding AEDA, these compounds were dete...... hiện toàn bộ
AbstractProducts containing scent are a part of daily life. The majority of cosmetics, toiletries, household and laundry products contain fragrance. In addition, there is exposure to fragrance from products that are used to scent the air, such as air fresheners and fragranced candles. In spite of this widespread use and exposure, there is little information availab...... hiện toàn bộ

AbstractThe essential oil, extracted by a current of air from the leaves of Lippia sidoides Cham, heated in a microwave oven for 5 minutes, was qualitatively identical with that obtained by conventional steam distillation for 60–90 minutes.
AbstractThe objective of this study was to determine which volatile compounds are primarily responsible for the aroma of fresh sweet cream butter. Static headspace analysis with gas chromatography–olfactometry (GC–O) was used to select key odourants and purge and trap–GC–mass spectrometry (MS) for their quantification. Twenty odour‐active compounds were detected in ...... hiện toàn bộ

AbstractThe essential oils from aerial parts of Tagetes minuta L. grown in Egypt, South Africa and the UK were obtained by hydrodistillation. Although they had similar constituents, the oils had different percentage compositions. Dihydrotagetone was the most abundant component of the oils from the UK (34.3 and 54.1%), while the oils from ...... hiện toàn bộ

ABSTRACTThis work was conducted as the initial part of the evaluation of flavoromics as a tool in flavour research. The objective was to develop and evaluate methods for the untargeted analysis of chemical stimuli of orange juice flavour. It considered for study all (ideally) low molecular weight compounds as candidate chemical stimuli in flavour perception (unbias...... hiện toàn bộ

AbstractVanillin incorporated almond gum/polyvinyl alcohol (PVA) composite nanofibers were prepared using electrospinning. The release mechanisms and kinetics of incorporated vanillin were evaluated in different aqueous food simulants (distilled water, 10% ethanol, 50% ethanol and 3% acetic acid) and simulated saliva. Vanillin content in different media was determi...... hiện toàn bộ

AbstractThe chemical compositions of the essential oils from the leaves and flowers of the endemic medicinal plant Bubonium graveolens, collected from south‐western Algeria, were established by GC–MS analysis. A total of 43 compounds were identified, representing, for leaves and flowers respectively, 97% and 97.6% of the total oil composi...... hiện toàn bộ
