Electronic Nose Chromatography

Abstract To ensure that chicken meat products are safe to consume it is important to be able to reliably determine its shelf-life. The dehydration and desalcoholization step can be conducted in parallel with electronic nose detection reducing.

1b comprising a sampling unit 10 unrelated chemical sensors and a pattern recognition software Win Muster v30 was used in this study.

Electronic nose chromatography. This study depicts a method of reducing adulteration in meats in which Electronic-nose E-nose and gas chromatography-mass spectrometer GC-MS were applied to identify adulterants in mutton. Therefore we used an electronic nose E-nose to explore the differences in odor information between the two cultivars for fast and robust discrimination. The Electronic nose allows continuous monitoring of volatile compounds.

These electronic noses incorporate three elements. The detection system of the electronic noses which consists of a. Both the enose and GC were able in most cases to separate fruit from different harvest maturities especially.

A portable electronic nose e-nose PEN3 Airsense Analytics GmbH Germany Fig. Two new methods gas chromatography-ion mobility spectrometry GC-IMS and ultrafast gas chromatography electronic-nose uf-GC E-nose were used to analyze the volatile organic compounds VOCs in four Chinese freshwater fishes at raw and cooked status. Back-flush gas chromatography is proposed as a novel tool for the pretreatment of vapour samples before analysis in the electronic nose.

Officinarum samples were detected by the E-nose and gas chromatography-mass spectrometry GC-MS respectively. The E-nose sensors and GC-MS data were analyzed respectively by principal. The multivariate structure of this electronic nose responses was then processed by principal component analysis PCA and hierarchical cluster analysis HCA.

By electronic nose enose or by gas chromatography GC for aroma and other volatiles as well as for soluble solids and acids. Odor and volatile components of all A. Duck meat was selected as a model adulterant due to its lower cost and similarity in flavor to mutton as well as being frequently adulterated in China.

Flavor profiles of high middle and low grades of Chinese green and black teas were comparatively analyzed by electronic nose gas chromatographymass spectrometry GCMS and quantitative descriptive analysis QDA in this study. Nanda4 Djoko Purwanto5 Rizki Anhar R. An analytical method to identify volatile organic compounds VOCs in the exhaled breath from patients with a diagnosis of chronic obstructive pulmonary disease COPD using a ultrafast gas chromatography system equipped with an electronic nose detector FGC eNose has been developed.

Details of the sensors used and their main applications have been previously described 46. According to the obtained results GC-MS and electronic nose can be used for the differentiation of the liquor origins and flavor types. An odor sensor array a data pre-processor and a data interpretation engine.

Sensory analysis showed marked differences among different grades of tea demonstrating it agreed well with the market price in tea grade classification. GC-IMS has the characteristics of fast detection speed and high sensitivity.

Aroma characterization of alcoholic beverages with sensor array electronic noses is a difficult challenge due to the masking effect of ethanol. The accuracy of the qualitative analysis of. Chromatography-mass spectrometry and electronic nose Huaixiang Tian Yongbo Shen Haiyan Yu and Chen Chen School of Perfume and Aroma Technology Shanghai Institute of Technology Shanghai China ABSTRACT To study the aroma features of different varieties of honey five honey samples from different botanical origins were characterized by sensory evaluation gas chromatography-mass.

Volatile data from the different harvest maturities and ripening stages were discriminated by using multivariate statistics discriminant factor analysis. To assess the applicability of ultra-fast gas chromatography and electronic nose technology in evaluation of poultry an analysis of the headspace of ground chicken meat samples refrigerated over a period of 7 days was performed. Gas chromatography-olfactometry GC-O electronic noses e-noses and electronic tongues e-tongues for in vivo food flavour measurement December 2013 DOI.
