Resumen

Se usaron dos paneles entrenados y cuatro paneles no entrenados para la comparación del desempeño entre los mismos. Cada panel entrenado estuvo conformado por seis jueces mientras que cada panel no entrenado estuvo constituido por 100 consumidores. Los atributos sensoriales que evaluaron los paneles fueron color blanco, textura granulosa al tacto, olor a cuajo, salado, grumoso en boca, suave en boca y aroma a suero. Para la evaluación de la discriminación se aplicaron diversos modelos de análisis de varianza (ANOVA) y para evaluar el consenso entre ambos tipos de paneles se utilizó la prueba de permutación (Rc). La comparación de los productos y atributos en el espacio sensorial fue evaluada mediante el Análisis de Componentes Principales (ACP) y la correlación global fue medida por la correlación vectorial (Rvglobal). Los resultados del ANOVA demostraron que los paneles entrenados fueron discriminantes en siete atributos mientras que los paneles no entrenados fueron discriminantes en seis atributos. El Rc mostró un consenso entre paneles entrenados y paneles no entrenados con valores 0.866 y 0.807, respectivamente. El ACP reveló similitudes entre tipos de paneles para el posicionamiento de los quesos y atributos en el espacio sensorial. El Rvglobal fue de 0.861 revelando que las configuraciones entre los tipos de paneles fueron similares. En conclusión los perfiles sensoriales entre paneles entrenados y no entrenados fueron similares.

Palabras clave: queso cuajada, perfil sensorial, paneles entrenados, paneles no entrenados, ACP
