Além do ferro ser muito pouco absorvido pelo organismo poucos alimentos contêm ferro em quantidade considerável. Assim, faz-se necessário estudar meios de enriquecimento estratégico de alguns alimentos. O aumento do teor de ferro no leite mediante um processo de coagulação poderia ser de utilidade visando obter um produto nutricionalmente mais completo. O ferro, na forma de Fe(NH4)2(SO4) 2.6H2O, foi adicionado ...
