Characterization of aroma‐active compounds in Jasminum sambac concrete by aroma extract dilution analysis and odour activity value

Abstract

Jasminum sambac is a flower and usually used in food, cosmetics or other chemical industries for its unique flavour characteristics in China. However, molecular sensory technologies have not applied to identify aroma‐active compounds in J sambac concrete. In this study, gas chromatography‐olfactometry (GC‐O), gas chromatography‐mass spectrometry and solvent‐assisted flavour evaporation were applied to isolate the odorants in three Chinese J sambac concrete (E1, E2 and E3) obtained from different companies. A total of forty‐nine, forty‐eight, thirty‐nine odorants were screened by GC‐O with aroma extract dilution analysis in E1, E2 and E3, respectively. The higher flavour dilution (FD) factors were linalool (19 683‐59 049, floral), methyl anthranilate (6561‐19 683, grape‐like) and benzyl acetate (2187‐19 683, floral). Twenty‐two aroma compounds were quantitated by gas chromatography‐flame ionization detection with internal standard, and then their odour activity values were obtained. Linalool, cis‐3‐hexenyl acetate, linalyl acetate, eugenol and methyl salicylate contributed greatly to the aroma of J sambac concretes. The aroma recombination model was established by mixing twenty‐two key odorants based on their measured concentrations, and the result revealed that the overall aroma profile was similar to that of the original sample. These results proved basic data for improvement of the national standard of jasmine concrete.

Characterization of volatile compounds in evening primrose oil after γ‐irradiate

“…OAV is calculated by the ratio of its concentration to its odour threshold, which is a common parameter in the research of aroma components. Jinglin Zhang identified the aroma‐active compounds in Jasminum sambac concrete by OAV 24 . We selected 23 aroma compounds that may cause the fishy smell of EPO for analysis, including 14 aldehydes, 5 alcohols, 1 ketone, and 3 acids, as shown in Table 2.…”

Insights into momentous aroma dominating the characteristic flavor of jasmine tea

“…Research shows that real jasmine tea (scented with fresh flowers) and fake jasmine tea (scented with aromatic essential oils) can be distinguished according to the disappearance of some grass/green smells (Wang et al, 2008). Further, the herbal scent was found to be related to either the sweet or green scent Zhang, Li, et al, 2021). In the same way, the excessive amount of flowers, scenting time, and scenting temperature were not necessarily conducive to the aroma quality of jasmine tea (An et al, 2022).…”

Jasmine (Jasminum sambac (L.) Aiton): Potential Utilization and Bioactivity

“…The removal of methyl anthranilate and the replacement of (R)-(−)-linalool by (S)-(+)-linalool causes a major change in the odor model [5]. The aroma of jasmine flowers is associated with a mixture of linalool, benzyl benzoate, farnesyl acetate, and methyl isoeugenol [4,16], cis-3hexenyl acetate, linalyl acetate, eugenol and methyl salicylate [4]. Methyl anthranilate and (R)-(−)-linalool) are the main aroma of jasmine tea flavor [5].…”

“…The J. sambac has the most significant economic value because it has a refreshing fragrance that is widely used in various industries [3], food, cosmetics or other chemicals [4,5]. These compounds (methyl anthranilate and (R)-(−)linalool) were determined as the main aroma of jasmine tea flavor [5].…”
