Chemical data were compared to the results obtained with the electronic nose and confirmed the assignment of the different unifloral samples. The results showed that the electronic nose, combined with chemical identification of the volatile species, allows to classify and discriminate the ...
volatile compounds and characteristic aroma of three kinds of Pu-erh tea were analyzed and identified by electronic nose (E-nose) and headspace solid phase microextraction (HS-SPME) combined with gas chromatography-mass spectrometry (GC-MS). The results showed that E-nose could ...
The results also showed that the electronic nose could analyze the process and level of spoilage for hairtail fish and pork. 展开 关键词: electronic nose sensor hairtail fish pork principal component analysis (PCA) total volatile basic nitrogen (TVBN) freshness shelf life ...
Thus, the E-nose showed the potential to be used as a preliminary tool for tea quality assessment. Furthermore, from the PCA results it is also possible to infer that the F3 data preprocessing method allowed achieving the best-unsupervised discrimination performance. 3.2. Supervised Multivariate ...

Moreover, through the electronic nose analysis of different concentrations of cis-3-hexen-1-ol with 25 other aroma components in green tea, we showed that the effect of cis-3-hexen-1-ol plays a profound effect on the overall aroma based on the experiments of reconstitution solution and ...
The results revealed that the corrected self-diffusion coefficient of the DES species was raised as the temperature was increased. This behavior implied that the H-bond network was diminished by rise of temperature. The dat, as presented in Table 6, showed that, chloride and choline ions moved...
Electronic sensors, such as electronic nose (E-nose) and tongue (E-tongue) are being developed and used in different food-related applications, including food processing. E-nose simulates the human nose to detect and identify volatile organic compounds, distinguishing complex odours with an array ...
A slower spoilage rate was observed in MAP storage than in iced. The electronic nose measurements are generally in agreement with the results of sensory evaluation, but give detailed information about the spoilage pattern and the composition of the headspace of red fish. 展开 ...
The correlation between the Delphi survey results and experts’ number of career years, nature of work and educational background was analysed. These results showed that the number of career years was significantly correlated with the accuracy of the experts’ judgements (Fig. 3A), with longer car...
