“…E-nose devices have been successfully applied to different fields particularly in food and beverage industries, such as snake fruit (Supriyadi et al, 2004), tomato (Hernández Gómez et al, 2008), and coffee (Falasconi et al, 2005). E-noses have also been used for identification of tea grade (Yu et al, 2008), prediction of tea quality (Dutta et al, 2003b), and monitoring of black tea fermentation process (Bhattacharyya et al, 2007).…”

a b s t r a c tConventionally, tea flavor is analyzed through the use of a combination of gas chromatography-mass spectrometry and human taste panel. These methods present time-consuming or inaccurate factor. In this work, a rapid, accurate and nondestructive approach was put forward to identify coumarin-enriched Japanese green teas and evaluate their particular flavor using electronic nose (E-nose) technique. The multivariable analyses including principal component analysis and cluster analysis were applied to distinguish the tea samples and evaluate the particular (coumarin-like) flavor of coumarin-enriched tea under different infusion conditions. A correct classification was achieved for the seven tea samples with different content of coumarin. The E-nose successfully characterized the drying temperature-dependently trend of coumarin content during the manufacture process of coumarin-enriched green tea. It also revealed that the comparatively low-infusion temperature and long-infusion time were favorable for the emission of coumarin-like flavor of the tea infusion. In addition, a comparatively newly developed ''absolute value expression" (AVE) method was employed to divide the tea flavors into quality and express them numerically. Using AVE, the role of coumarin in the total flavor of coumarin-enriched green tea was elucidated. These results suggest that E-nose could be employed to identify the green teas with particular flavor and evaluate the tea flavor.

“…Parastar et al combined fingerprint analysis using GC–MS with chemometric to analyse secondary metabolites of citrus peels [17]. Fingerprint analysis using mass spectrometry and electronic nose based on sensors is also used for determination fruit maturity [18]. Previous reports show the difference in aroma of limequat and kumquat, what determines difference in their fingerprints [11].…”

Citrus fruits are very popular food products. There are many species and varieties of them. There are also documented cases of some citrus fruits causing a severe allergic reaction. Some species of the citrus fruits, especially hybrid ones show a reduced allergenic effect due to the lack of seeds. There is a need for rapid methods for evaluation of citrus’ botanical origin. During research, the headspace of three citrus fruits Citrus Aurantifolia, Citrus japonica, and Citrus × floridana was analysed using electronic nose based on ultrafast gas chromatography and gas chromatography with mass spectrometry. In the paper, two approaches were compared. The usefulness of an electronic nose to control the quality of hybrids was demonstrated. The results obtained during ultrafast gas chromatography analyses were subjected to statistical analysis. Four chemometric methods namely: principal component analysis (PCA), discriminant function analysis (DFA), soft independent modeling of class analogies (SIMCA), statistical quality control (SQC) were used to distinguish between limequat and its parent fruits. Electronic nose combined with chemometrics is a novel analytical tool for hybrid fruits’ classification due to their botanical origin. It can supplement established techniques by providing results in a short time and at a low cost.Graphical abstract

“…Supriyadi et al found that electronic noses could detect and distinguish the different maturation periods of salak. (10) They also used a GC-odor detector to determine ten characteristic components that could influence odors and analyzed maturity-related changes in components by MS online analytical processing (OLAP) with the use of an electronic nose. Italian researchers Buratti et al (11) provided sensory descriptions of wines of different Italian brands by combining an electronic nose with a spectrophotometer.…”

There are a variety of methods to detect odorant molecules, including gas chromatography (GC) and its related coupled techniques, electronic noses, and olfactory receptor (OR)-based biosensors. Nevertheless, studies in which cell and cell signaling amplifier systems were directly utilizied to detect odors are very few. In this review, we aim to provide some references and suggestions for researchers in related fields by summarizing OR sensors and olfactory cell signaling cascade amplifier systems. In this paper, we summarize the detection methods for odorants, introduce the research and progress on OR sensors, and present a proposal of utilizing cell or tissue signaling cascade amplifier systems to amplify electrochemical signals and the use of the G protein signaling cascade amplifier system to prepare electrochemical biosensors. In recent years, the detection technology of electrochemical sensors has matured. Meanwhile, olfactory sensation within organisms basically transfer nerve signals or metabolic endocrine signals in the form of electrochemical signals. Therefore, ORs combined with cell signaling cascade amplifier systems, as well as electrochemical sensors of signal cascade amplifier systems, have incredible prospects for development and application. The proposal of OR electrochemical biosensors and their cell signaling cascade amplifier systems, provides a new idea and a quantitative method for the detection and assessment of odorants and their physiologic processes in the nervous system.
