Sobre IBD

As vitaminas são essenciais para o corpo humano, sendo necessárias para os seus diversos processos bioquímicos e fisiológicos. O ácido ascórbico (vitamina C) é uma vitamina hidrossolúvel presente em muitos sistemas biológicos e alimentos (legumes e frutas frescas). A forma mais fácil e melhor de ingerir vitamina C é através de uma dieta líquida. Atualmente, existem muitos sumos líquidos disponíveis no mercado que alegam ter elevados teores de vitamina C. Este trabalho incide sobre o teor de ácido ascórbico (vitamina C) em sumos, bebidas, amostras em pó e refrigerantes comercializados em Islamabad, no Paquistão. Os resultados foram comparados com os valores indicados nos rótulos das embalagens. O método de determinação do ácido ascórbico por polarografia foi descrito em pormenor.
