Resumen

este estudio, se evaluaron las características fisicoquímicas de almidones extraídos de diez cultivares diferentes de yuca, cultivados en diferentes tipos de suelo. Existen variaciones significativas en las proporciones de almidón dañado durante la extracción, incluso en muestras del mismo cultivar. El contenido de amilosa difiere entre cultivares e incluso dentro de las mismas cosechas en diferentes suelos (que van del 20,00 al 24,07%). Según el tipo de suelo, los almidones presentaron diferentes valores para el índice de cristalinidad. Este resultado indica la necesidad de caracterizar los almidones, incluso cuando proceden del mismo cultivar. Los resultados obtenidos se pueden utilizar como una herramienta de apoyo para mejorar la yuca, optimizando el proceso de selección y mantenimiento de un banco genético. El análisis quimiométrico (PCAs y racimos), permite distinguir cultivares de acuerdo a sus características físico-químicas y peculiaridades funcionales, sugiriendo sus diferentes usos.
