[Quality comparison of pistachios based on sensory analysis] | Comparacion de calidad de pistachos mediante analisis sensorial

Inglés. Using a sensory analysis test, the pistachios of the Sfax, Kerman and Red Aleppo varieties produced and processed in Delicias, Chihuahua, Mexico, were compared with pistachios from California, USA, and Iran. The appearance of the shell of the nuts was similar for the three origins; however, pistachios from California and Delicias had the best tendency in this characteristic. About the appearance of kernels, pistachios from Iran wore outstanding, because their kernel is more plump and it does not have much wrinkles. There was not statistical difference in taste among origins tested. Pistachios from Delicias were well graded in this attribute. It is considered that the processing of nuts (salting and roasting) affects their appearance, but it affects mainly the taste that the taster enjoys

Español; castellano. Mediante una prueba de analisis sensorial se compararon pistachos de las variedades Sfax, Kerman y Red Aleppo producidos y procesados en Delicias, Chihuahua (Mexico), con pistachos de California (EUA) e Iran. La apariencia con cascara resulto similar en las nueces de las tres procedencias, con tendencia a ser mejor calificadas las de California y Delicias. Los pistachos de Iran sobresalieron en el aspecto de la almendra que es regordete y con escasas arrugas. En sabor no hubo diferencia estadistica entre procedencias, mostrando los pistachos de Delicias buen comportamiento en esta caracteristica. Se considera que el procesado de las nueces (salado y tostado) influye en su apariencia, pero sobre todo en el sabor que detecta el degustador final
