Hair sheep lamb meat ageing-an instrumental odour analysis
Background: The electronic nose is a system of sensors which is far from a real nose’s sensitivity, it is a device based on chemical, biological and electro chemical responses from the compounds present in food products known as the aromatic footprint which might discriminate different food states....

Retrieved from www.scopus.com01214004https://www.scopus.com/search/form.uri?display=basicBackground: The electronic nose is a system of sensors which is far from a real nose’s sensitivity, it is a device based on chemical, biological and electro chemical responses from the compounds present in food products known as the aromatic footprint which might discriminate different food states. Objective: The aim of this work was to evaluate the effect of feeding system and ageing times in meat samples taken from Doper X Colombian lambs by electronic nose analysis Methods: Fiftyfour 10-week-old Dorper X Colombian lambs were used in 2 feeding systems: grazing and semifeedlot (n=27). Samples were analyzed in 3 ageing conditions (0, 7 and 15 days). 10 g of sample was weighed, vacuum-packed and cooked until reaching 72°C internal temperature and stored at 4°C. The samples were placed in 40 mL vials closed with 22 mm PTFE-silicone septa to start the analysis and then placed at 16°C for 10 minutes. Afterwards, they were incubated at 35.5°C for 20 minutes, a 100 mL/min flow was selected to avoid presenting low responses in the sensors. 40°C was established to prevent water condensate formation that could have interfered in the sensors’ response. Results: The obtained results showed that discrimination was possible between PC1 with 90.6% and PC2 with 72.6% (data variability) in feeding systems with 88.89% (correct discriminating function) due to the volatile compounds forming the aromatic profile of cooked lamb meat, especially sulphur aromatic ones. Conclusions: A greater number of sensors were necessary for discriminating between different ageing times on account of the multiple aroma-producing reactions.application/pdfengVitae;Vol. 23, 2016, páginas 824-827AgriculturaDerechos Reservados - Universidad de Ciencias Aplicadas y Ambientaleshttps://creativecommons.org/licenses/by-nc-sa/4.0/info:eu-repo/semantics/openAccessAtribución-NoComercial-CompartirIgual 4.0 Internacional (CC BY-NC-SA 4.0)http://purl.org/coar/access_right/c_abf2https://www.scopus.com/search/form.uri?display=basichttps://search.proquest.com/openview/1adc2d1eb71aad80bf1ae8ce29d9e3c7/1?pq-origsite=gscholar&cbl=1806352Hair sheep lamb meat ageing-an instrumental odour analysisAnalisis instrumental del aroma en la maduración de carne de corderos de peloArtículo de revistahttp://purl.org/coar/resource_type/c_6501http://purl.org/coar/resource_type/c_2df8fbb1info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionTexthttp://purl.org/redcol/resource_type/ARThttp://purl.org/coar/version/c_970fb48d4fbd8a85Aromatic footprintElectronic noseLamb meaOdorCarne de corderoEnvejecimientoOvejaPeloOlorPublicationORIGINALout (5).pdfout (5).pdfapplication/pdf1050253https://repository.udca.edu.co/bitstreams/7fc3e26c-7bf5-41af-84b4-2966260b0db1/downloadbc188c3933d43486951798fc18f9f8beMD51TEXTout (5).pdf.txtout (5).pdf.txtExtracted texttext/plain14815https://repository.udca.edu.co/bitstreams/c75402fa-1031-4019-8c41-3910e1a370ca/downloadd427b7b31cadcf39350b516a400c9cebMD52THUMBNAILout (5).pdf.jpgout (5).pdf.jpgGenerated Thumbnailimage/jpeg7904https://repository.udca.edu.co/bitstreams/5a26b62f-f020-4da0-9f1c-47d852074755/download6ad17225ed5bcb8af9bd57518bd58cc3MD5311158/3206oai:repository.udca.edu.co:11158/32062024-05-09 14:38:43.744https://creativecommons.org/licenses/by-nc-sa/4.0/Derechos Reservados - Universidad de Ciencias Aplicadas y Ambientalesrestrictedhttps://repository.udca.edu.coRepositorio - Universidad de Ciencias Aplicadas y Ambientales UDCA.bdigital@metabiblioteca.com |
