Identification of corn starch from Catamarca: application to two archaeological cases

In this paper we introduce a statistical model to discriminate different maize types in archaeological starch grains recovered from pottery and ground stone tools. The model was developed using a wide database of starch grains from maize landraces native to the Argentine Northwest. We carried out a...

Northwestern Argentina maize landraces discriminant statistical model Arqueobotánica Zea mays L. maíces nativos del NOA modelo estadístico discriminante In this paper we introduce a statistical model to discriminate different maize types in archaeological starch grains recovered from pottery and ground stone tools. The model was developed using a wide database of starch grains from maize landraces native to the Argentine Northwest. We carried out a Discriminant Analysis using the stepwise methodology. This analysis allowed us to assign the archaeological starch grains to different maize types, defined by their endosperm texture: flint, floury, sweet, dent and flint-floury. The identification of different maize types in archaeological samples allowed us to discuss food and beverage preparation and consumption practices in Catamarca during the pre-Hispanic period. En este trabajo presentamos un modelo estadístico para discriminar tipos de maíz a partir de los gránulos de almidón arqueológicos que fueron recuperados en vasijas cerámicas e implementos de molienda de piedra. El modelo fue generado a partir del estudio de una amplia base de datos de gránulos de almidón de maíces nativos del Noroeste argentino. Se llevó a cabo un Análisis Discriminante utilizando el método de inclusión por pasos. Este análisis nos permitió asignar los ejemplares arqueológicos a los diferentes tipos de maíz, definidos por su textura de endosperma: córneo, harinoso, dextrinoso, dentado y córneo harinoso. La identificación de tipos de maíz en las muestras arqueológicas permitió discutir las potenciales prácticas de preparación y consumo de alimentos y bebidas catamarqueñas en tiempos prehispánicos.
