Abstract in Portuguese
O objetivo do trabalho foi avaliar através da análise química e protéica o valor nutricional das folhas de couve-manteiga, couve-flor e espinafre bem como a biodisponibilidade de cálcio nessas folhas. Verificou-se que a folha de couve-flor mostrou o melhor valor químico. No ensaio biológico feito com ratos, a dieta de couve-manteiga, mostrou os melhores valores para os parâmetros nutricionais avaliados bem como a melhor retenção, e biodisponibilidade de cálcio. A dieta constituída com folha de espinafre provocou a morte dos animais, provavelmente devido a presença de ácido oxálico e de outros fatores antinutricionais.
Title in English
Chemical and proteic evaluation and bioavailability of calcium on cole, cauliflower and spinach leaves
Abstract in English
The paper purpose was to check through chemical and protein analysis the nutritional value of cole, cauliflower and spinach leaves as well as calcium bioavailability in these leaves. It was found out that cole leaf has presented the best chemical value. In the biological test made with rats, cole diet, has shown the best data for the evaluated nutritional parameters as well the best calcium retention and bioavailability. The diet made up spinach leaf has brought death to test animals, probably due to oxalic acid presence and other non-nutritional factors.
