title = "Analysis of volatile compounds in Paracentrotus lividus by HS-SPME/GS-MS and relation to its sensorial properties",
abstract = "This study characterizes the sensory features and odour active volatile organic compounds (VOC) profile of P. lividus, taking into consideration the sex and harvest location. Sensory evaluation was performed by an experienced panel through the application of Projective Mapping paired with Ultra Flash Profile. VOC were determined by headspace solid-phase microextraction coupled to gas chromatography mass spectrometry (HS-SPME/GC-MS). Data showed that sea urchin gonad's sensory properties were mainly influenced by sex, while their volatile profile was affected both by sex and harvest location. Males tended to be sweeter, softer and with a pale-yellow colour, while females revealed an intense sweet tropical taste and a bright-orange colour. PCA unveiled variations in the levels of p-xylene, 1,2,4-trimethylbenzene and m-xylene between locations, whereas levels of β-pinene, 2,4-dimethyl-1-heptene,D-limonene and heptane discriminate sex. This study contributes to a better characterization of the sensory profile of sea urchin gonads aiming the selection of premium gonads.",
