Fecha de publicación: | oct-2008 | Editor: | Elsevier | Citación: | Meat Science 80 (2): 315-325 (2008) | Resumen: | This work studies the relationship between 45 volatile compounds and 17 sensory attributes (13 flavour perceptions) of dry-cured hams. Volatile compounds were quantified by SPME-GC while the sensory assessment was carried out by 13 panellists. GC-sniffing was used to determine the odour impact zones of the chromatogram. The odour thresholds of the volatile compounds and their sensory characterisation were determined by dilution analysis. Six sensory attributes (acorn odour and flavour, rancid odour, rancid taste, fat rancid and fat pungent flavours) were explained by regression equations (adjusted -R(2)⩾0.70) based on ten compounds: benzaldehyde, 2-heptanone, hexanal, hexanol, limonene, 3-methylbutanal, 3-methylbutanol, 2-nonanone, octanol, pentanol. Acorn flavour attribute was successfully emulated by mixing the volatile compounds selected by the equation. Its odour was evaluated by assessors that gave a sensory description that matches with the target. All the procedures performed for the elucidation of volatile-attribute relations showed a basic agreement in their results. | Descripción: | 22 Páginas.-- 1 Figura.-- 4 Tablas | Versión del editor: | https://doi.org/10.1016/j.meatsci.2007.12.015 | URI: | http://hdl.handle.net/10261/341868 | DOI: | 10.1016/j.meatsci.2007.12.015 | ISSN: | 0309-1740 |
