Efeito da germinação de soja CV. BR-13 e Paraná sobre ácido fítico, fósforo total e inibidores de tripsina

Este trabalho foi conduzido para avaliar o efeito da germinação sobre os constituintes antinutricionais da soja, ácido fítico, P total e inibidores de tripsina, que interferem na utilização de proteínas e outras substâncias. A diminuição no aproveitamento de nutrientes resulta em inibição de crescimento, hipoglicemia ou danos a tecidos animais. Para os ensaios foram utilizadas as cultivares de soja (Glycine max (L.) Merrill ) BR-13 e Paraná. As sementes foram incubadas em câmara de germinação a 25°C e 100% de umidade, de 0 a 72 horas, com coleta de amostras em intervalos eqüidistantes de seis horas. A cultivar Paraná apresentou teores superiores de ácido fítico, P total e inibidores de tripsina, em relação à cultivar BR-13. As análises de variância e comparações entre médias indicaram que houve aumentos significativos (p < 0,05) nos teores de P total (8,5% e 3,6% nas cultivares BR-13 e Paraná, respectivamente) e nos níveis de inibidores de tripsina (22,05% e 17,10% nas cultivares BR-13 e Paraná, respectivamente), e reduções nos teores de ácido fítico (15,96% e 9,46% nas cultivares BR-13 e Paraná, respectivamente), em 72 horas de germinação.
