Resumen
Se evaluó la similitud entre las técnicas Perfil Flash y Napping®-Ultra Perfil Flash (Napping® -UPF) mediante el coeficiente de correlación vectorial (Rv). Para ello, se caracterizaron sensorialmente dos marcas de hot-dog comerciales del mercado limeño y dos formulaciones obtenidas por Ingeniería Kansei. En el Perfil Flash los consumidores generaron y calificaron sus propios descriptores, que fueron procesados mediante el análisis Procrustes generalizado. En el Napping® -UPF los consumidores posicionaron y describieron las muestras de hot-dog en una hoja tamaño A3. Las coordenadas (x, y) de cada muestra y los términos descriptivos fueron procesados usando el análisis factorial múltiple. El índice de consenso (Rc = 61,2 %) y la superposición de las elipses de confianza en las muestras HD2.1 y HD2.2 evidenciaron que, éstas no tenían una diferencia sensorial significativa (p-valor < 0,05). Finalmente, el valor del Rv (0,93) determinó una alta similitud entre ambas técnicas sensoriales.
