An electronic nose is an electronic sensing device intended to detect odors or flavors. Statistical multivariate analysis of the data showed the capability of E-nose to predict sensorial analysis scores and to monitor aroma profile changes during storage. Search for more papers by this author.

Gao et al 2012. Flash gas chromatography electronic nose HERACLES Neo is dedicated to the analysis of your products aroma as well as chemical molecules composing the smell with AroChemBase option. Sensors and Actuators B.

The flavor profile of five brands of instant vermicelli seasonings were identified by headspace solid-phase micro-extraction coupled with gas chromatography-mass spectrometry HS-SPMEGC-MS and electronic nose e-nose. Truffles were stored at different conditions for 7 days. According to the obtained results GC-MS and electronic nose can be used for the differentiation of the liquor origins and flavor types.

This system can imitate human olfactory. The flavour of food products is important as a characteristic sensory feature. Flavor dilution factors indicated that hexanal grassy 1octen3ol mushroomlike and 23pentanedione milky.

Practical applications 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. Overall sensory evaluation showed that metallic and grassy in Chinese carp were heavier than those in American. A study of headspace of white truffles by using Electronic nose E-nose gas chromatographymass spectrometry GCMS and sensory analyses was performed.

Thanks to its numerous applications its high precision and ease of use control the sensory profile of your products to better satisfy your customers. Coupling electronic nose with GCMS improves flavor recognition and grade differentiation of Zhenjiang aromatic vinegar. The e-nose is able to give quantitative response to a comprehensive VOCs profile but in this case individual VOCs remain unidentified.

The multivariate structure of this electronic nose responses was then processed by principal component analysis PCA and hierarchical cluster analysis HCA. Data curation Validation Writing - original draft. The expression electronic sensing refers to the capability of reproducing human senses using sensor arrays and pattern recognition systems.

The most frequently used sensors of e-noses are electrochemical amperometric and conductometric piezoelectric and optical smell-sensing and those based on GC and MS Dymerski et al. An e-nose is an instrument that is designed to sense odours rather than individually and typically differentiates them using an array of diverse chemical sensors. Alkenes alcohols aldehydes and ketones were the major volatile.

GC-O electronic nose e-nose electronic tongue e-tongue odour taste. This method has been applied in the analysis of various. The number and type of sensors as well as their selectivity and sensitivity depend on the e-nose application.

An alternative is the electronic nose e-nose which can be used as a non-invasive rapid portable piece of equipment that may also provide results at a lower cost per test. Chemical 160 2011 pp. The electronic nose e-nose consists of a gas sensor array to provide a fingerprint of exhaled breath breath print BP by detecting VOCs through multiple sensors.

Headspace E-nose measurements and sensory analyses were performed each day. Truffles volatile molecules were also extracted by headspace solid phase microextraction technique and separated and identified by GCMS. The electronic nose does not provide qualitative or quantitative results concerning the components in the sample but it can be used to successfully monitor and differentiate products.

As an effective method to complement sensory evaluation and GC-MS the electronic nose has become a trusted technology for the analysis of food flavor. Truffles were stored at different conditions for 7 days. Article Download PDF View Record in Scopus Google Scholar.

Li Wang School of Food and Biological Engineering Jiangsu University Zhenjiang Jiangsu China. GC-IMS and uf-GC E-nose could be developed further to distinguish aquatic products based on VOCs. A study of headspace of white truffles by using Electronic nose E-nose gas chromatography-mass spectrometry GC-MS and sensory analyses was performed.

GC-MS showed that the volatile compounds of instant vermicelli seasonings were significantly different. Analysis of volatile compounds of Mesona Blumes gumrice extrudates via GC-MS and electronic nose. The overall odor profile was analyzed by electronic nose.

Characterization of selected Harbin red sausages on the basis of their flavour profiles using HS-SPME-GCMS combined with electronic nose and electronic tongue. Zhang et al 2021. And for the quality.
