CORRELATION BETWEEN PERSONALITY TRAITS AND DISCRIMINATIVE ABILITY OF A SENSORY PANEL CORRELACI????N ENTRE RASGOS DE PERSONALIDAD Y HABILIDAD DISCRIMINATORIA DE UN PANEL SENSORIAL

摘要

Resumen The correlation between personality traits and judge performance was studied. The 16-personality factors questionnaire of Cattell was applied to 200 participants. Judge performance was evaluated following a series of taste and odor tests. Judges were then asked to rank basic different taste solutions. Finally, judges discriminated between purified water and sweet solution (29 mM) using the triangle test. Participant's health habits (smoking and alcohol consumption) were reported. Results showed that, out of 200 recruited participants, 66 were found discriminators. No correlations between judge performance and health habits were found. Two personality traits were correlated to sensory discrimination ability: The serious type personality was correlated to discriminators, while the experimenting type personality correlated to non-discriminators. These results suggest the importance of using personality trait tests during sensory judge selection. Los rasgos de personalidad y la capacidad discriminatoria de 200 candidatos a jueces sensoriales fueron estudiados. Los rasgos de personalidad se evaluaron a trav????s del cuestionario de factores de personalidad de Catell y el desempe???±o de los jueces se evalu???3 con pruebas de reconocimiento de olor y de sabor, pruebas de ordenaci???3n a diferentes niveles de dulzor y pruebas discriminatorias entre soluciones de sacarosa al 29 mM y agua purificada, usando la prueba triangular. Algunos h????bitos de salud de los participantes (fumar y consumo de alcohol) fueron reportados. Los resultados mostraron que de los 200 participantes, 66 resultaron ser discriminadores. No se observ???3 correlaci???3n entre los h????bitos de salud y la capacidad discriminatoria de los jueces. Dos rasgos de personalidad presentaron correlaci???3n con la capacidad discriminatoria de los jueces: La personalidad ?￠???? seria ?￠???? se correlacion???3 con jueces discriminatorios en las pruebas sensoriales, mientras que la personalidad ?￠???? experimentador ?￠???? se correlacion???3 con candidatos sin capacidad discriminatoria. Estos resultados sugieren la importancia del uso de pruebas de personalidad en la selecci???3n de jueces sensoriales.
