Resumo

Neste estudo, foram avaliadas as características físico-químicas de amidos extraídos de dez diferentes cultivares de mandioca, cultivadas em diferentes tipos de solos. Há significativas variações nas proporções de amido danificado durante a extração, mesmo em amostras da mesma cultivar. O teor de amilose difere entre cultivares e mesmo dentro das mesmas colhidas em diferentes solos (variando de 20,00 a 24,07 %). De acordo com o tipo de solo, os amidos apresentaram distintos valores para o índice de cristalinidade. Este resultado indica a necessidade de caracterização de amidos, mesmo quando têm origem em uma mesma cultivar. Os resultados obtidos podem ser usados como ferramenta suporte para melhoramento da mandioca, otimizando o processo de seleção e manutenção de um banco genético. A análise quimiométrica (PCAs e agrupamentos), permite distinguir cultivares de acordo com as suas características físico-químicas e peculiaridades funcionais, sugerindo seus distintos usos.
