Principles and recent advances in electronic nose for quality inspection of agricultural and food products

Applications of an electronic nose in the prediction of oxidative stability of stored biodiesel derived from soybean and waste cooking oil

“…PCA creates new variables known as principal components (PCs) that are uncorrelated one with another and interpreted by association with original variables through the corresponding factor loadings. PCA has been widely employed in the analysis of olfactory profiles [16] , [46] , [47] , [48] .…”

“…An electronic nose (or e-nose) is a multisensory system that can analyze the volatile components in the headspace of a sample. E-noses have found wide application in the food and beverage industries, in agriculture and forestry, in medicine and health-care, and in military and civilian security systems [15] , [16] . However, application of this technology to the characterization of biodiesel is in its infancy, even though progress in the field would be very especially important for biodiesel producers, distributors and retail outlets.…”

Quality grade classification of China commercial moxa floss using electronic nose

“…With the help of good performance of sensor arrays along with advances in pattern recognition algorithms, e-nose devices have already been established as effective gas-sensing tools for the quality evaluation of various food and agricultural products. [ 21 ] The findings from this study indicated that on the basis of e-nose technology, data refinement for different aroma volatile compounds of moxa floss could be achieved for better discrimination performance and data clustering which is useful in reducing cost and time in practical application.…”

Improvement strategies of food supply chain through novel food processing technologies during COVID-19 pandemic

“…Similarly, the adulteration of pork in mutton mince ( Tian et al, 2013 ), differentiation of rice varieties ( Zheng et al, 2009 ), and discrimination of fish species ( Güney & Atasoy, 2015 ) were also accomplished by E-nose. The details of its principles, methods, applications, and recent advances in its uses in food sectors were recently reviewed by many researchers ( Mohd Ali et al, 2020 ; Shi et al, 2018 ; Tan & Xu, 2020 ). Since E-nose is relatively faster, and less destructive, it can be used for real-time odor detection without direct human involvement.…”
