Electronic/artificial noses are being developed as systems for the automated detection and classification of odors, vapors, and gases. An electronic nose is generally composed of a chemical sensing system (e.g., sensor array or spectrometer) and a pattern recognition system (e.g. PDF | Electronic noses are customized devices employed to detect and to identify gaseous mixtures, even to give the concentration of the atmosphere. Electronic nose. What is electronic nose? Application areas. Wireless Sensor Networks Based Electronic-nose used for monitoring and improving air.

Then various herbs and spices were investigated in order to screen the possible ingredients entering the formulas prior to re-formulation. Electrochemical Sensing of Nitroaromatic Explosives. They are used by vendors in order to: Optical Microsensor Arrays for Explosives Detection. Next, different pattern recognition techniques are presented to enhance the performance of chemical sensors.

The sample set includes snacks obtained based on different manufacturing processes that lead to different textures. The samples were pulverized using blade mixer before analysis, to get homogenised samples. The panel of trained assessors used a Quantitative Descriptive Analysis based on 26 descriptors among which 7 for texture, 5 for aroma, and 14 for flavor.

The combination of E-Nose and E-Tongue measurements showed the same grouping of samples as the sensory panel. Their aromatic profiles were first compared.

The Electronic Nose and Tongue: They are more and more used nowadays at the production floor as easy, reliable and fast organoleptic Quality Control instruments. They do give simple electronic signature correlated with the smell and taste qualities quantitative or qualitative.

They can also provide a chemical firewall instrument or early warning process indicators of any changes in the raw materials profiles or finished products qualities.

Electronic Nose and Tongue instruments are now included in sales and marketing tools. They are used by vendors in order to: Instrumental multi-sensory characterization of processed cheese This study showed the interest of combining electronic nose, electronic tongue and electronic eye analyses in order to achieve a detailed sensory evaluation of food products.

This all-in-one instrument, both electronic nose and ultra fast gas chromatograph, performs overall odor profiling and chemical composition analysis in one run. Skip to main content.

The biology can be employed either to understand the way insects locate odorant sources, or to understand the signal processing neural pathways. Next is a discussion of some of the new types of electronic noses; namely, a fast GC column with a SAW detector and a micromechanical sensor. Finally, the important issues of sampling technologies and the design of the microfluidic systems are considered.

In particular, the use of pre-concentrators and solid phase micro extractors to boost the vapour concentration before it is introduced to the chemical sensor or electronic nose.
