Aroma is one of the most important quality attributes of black tea infusions. In this study, the aroma quality of 44 Dianhong black tea (DBT) infusions were investigated by rapid gas phase electronic nose (GC-E-Nose) combined with multivariate statistical anal. for the first time. Among 61 volatile compounds identified, the most abundant ones were aldehydes. Both partial least squares discriminant anal. (PLS-DA) and Fisher discriminant anal. (FDA) could effectively classify the aroma quality of DBT infusions. The prediction accuracy of FDA (95.2%) was higher than that of PLS-DA (78.6%). Moreover, stepwise multiple linear regression was shown to accurately predict the quality score of DBT infusions, and the Rp value of the sensory score of the predicted model was 0.94. Furan, Me acetate, 2,3-pentanedione, limonene, and linalool were found pos. correlated with the aroma quality of DBT infusions, while 3-ethylpentane, 1-pentene, (E)-2-hexene, and Me eugenol were neg. correlated with the aroma quality of DBT infusions. These results contribute to understand that rapid GC-E-Nose technol. is a supplement to the objective sensory evaluation, and provide a new tech. method for the quality evaluation and control of tea infusions. In the experiment, the researchers used many compounds, for example, 6-Allyl-4-methoxybenzo[d][1,3]dioxole (cas: 607-91-0Application of 607-91-0).
6-Allyl-4-methoxybenzo[d][1,3]dioxole (cas: 607-91-0) belongs to dioxole derivatives. Dioxoles, particularly fluorinated dioxoles, are used as co-monomers to make polymers that find use in forming protective coatings for chemical resistance. 1,3-Benzodioxole can be synthesized from catechol with disubstituted halomethanes.Application of 607-91-0
