“…Di Natale et al explored the use of measurements of two electronic noses to detect freshness of code-fish fillets. The results here illustrated confirmed that electronic nose systems based on different sensor technologies generally improved the performances with respect to a single technology [18].…”

In this paper, rapid freshness analysis method of mantis shrimps (MSs) (Oratosquilla oratoria) by using electronic nose (e-nose) was investigated. Shrimps were stored at 4°and -20°. E-nose responses to samples were measured. Meanwhile, appearance of MS was recorded. Total volatile basic nitrogen (TVB-N) index was examined to provide a standard freshness indicator for samples according to Chinese national standard protocol. E-nose measurement data was processed by principal component analysis (PCA) and non-linear bistable stochastic resonance (SR). Experimental results demonstrated that e-nose sensitively responded to shrimps. PCA results failed to discriminate all shrimps. SR signal-to-noise ratio (SNR) spectrum successfully discriminated all shrimp samples stored at 4°and -20°. E-nose MS freshness degree forecasting models were developed using SNR maximums. Combining TVB-N examination results, the forecasting accuracy of developed freshness analysis model is 91.67 %. The proposed method had some advantages including rapid analysis, easy operating, non-destructive, low cost, etc.

“…O'Connell et al (2001) proposed a novel way for Argentinean hake freshness discrimination using E-nose combined with PCA based on glass syringe manipulation. Natale et al (2001)classified freshness for cod fish fillets using E-nose combined with partial least square discriminant analysis (PLS-DA), as characterized by the analysis results of trimethylamine (TMA) and TVB-N. El Barbri et al (2009) realized sardine freshness assessment using E-nose combined with PCA, support vector machines (SVM), and PLS. Verma and Yadava (2015) reported the use of E-nose combined with fuzzy c-means (FCM) clustering algorithm to discriminate fish freshness according to the TMA content.…”

In this paper, a portable electronic nose (Enose) system was designed, and its application in K value prediction for large yellow croaker (Pseudosciaena crocea) was also explored. E-nose responses to croaker samples were measured for 8 days. Microbiological and chemical indexes including total viable count (TVC), K value, and GC-MS were synchronously examined. Principal component analysis (PCA) and stochastic resonance (SR) were utilized for E-nose measurement data analysis. Results suggested that croaker's K value increased rapidly due to microbial propagation. GC-MS results presented the information of volatile gas emitted by croaker samples, and provided reliable references for E-nose responses. PCA method could not discriminate all croaker samples, while SR signal-to-noise ratio (SNR) maximum (Max SNR ) values quantitatively discriminated all samples. Large yellow croaker K value predictive model was developed by linear fitting regression between K values and Max SNR values with a regression coefficient (R 2 ) of 0.96. Validating experiment results demonstrated that the forecasting accuracy of this model is 83 % the regression coefficient of the developed model was 0.83. E-nose is a useful tool for food quality examination. But, there are no such standard references for E-nose examination, which limits the applications of this technique. The method proposed here will promote the applications of E-nose in aquatic product quality rapid analysis.

“…However, QMBs arrays can capture not only amines, but also the other compounds involved in the transition from freshness to spoilage, thus allowing for a detection of the changes occurring few hours after catching of a fish [24,25]. Other applications to food analysis include the identification of peaches cultivars [26], the determination of the optimal picking time of apples [27] and the detection of off-flavors in packaged chocolate [28].…”

ABSTRACT:The impressive chemistry shown by porphyrins in natural systems is particularly attractive for exploitation in chemical sensors. In these devices the sensing mechanisms can mimic most of the porphyrin biological reactivity, such as reversible binding, activation of small molecules, redox activity, and photoactivated processes. The simultaneous presence of multiple binding mechanisms allows porphyrins to interact with a large variety of analytes. This feature reduces the selectivity, but prompts the development of sensor arrays, where the cross-selectivity of more sensors is used to classify and identify samples characterized by a complex composition. Since 1995 the Sensors Group of the University of Rome Tor Vergata has exploited these features to prepare sensor arrays based on different transducers and aimed at several applications. These kinds of devices have been reported as electronic noses (gaseous phase analytes) and electronic tongues (liquid phase analytes) to underline that their working mechanisms are tentatively similar to that of biological senses. We report here some of the results obtained.
