Abstract in Portuguese
Os minerais essenciais participam de várias funções vitais do organismo, suas deficiências contribuem de maneira significante para a morbidade e mortalidade na infância, especialmente nos países em desenvolvimento, sendo consideradas como problema de saúde pública em todo o mundo. Minerais apresentados na forma de complexos orgânicos têm sido propostos para correção destas deficiências por apresentarem maior biodisponibilidade, quando comparados aos equivalentes sais inorgânicos. Os minerais cobre, ferro, manganês e zinco são essenciais aos organismos vivos (humano e animal), a manutenção de seus níveis de acordo com as necessidade fisiológicas contribuem para a manutenção da saúde, resultando em benefícios econômicos. No presente trabalho foi realizada a preparação e caracterização físico-química de complexos dos minerais Cobre (Cu), Ferro (Fe), Manganês (Mn) e Zinco (Zn) com hidrolisados parciais de proteína de soja. As hidrólises utilizando as enzimas Aranzime e Alcalase foram mais eficientes que as demais hidrólises enzimáticas ou ácidas, entretanto somente a Alcalase foi aprovada para a manufatura de produtos alimentares de consumo humano. A coordenação entre os metais e o hidrolisado pode ser confirmada por pelo deslocamento das bandas ?NH2, ?aCOO- e ?sCOO-. Os complexos obtidos de cobre, ferro, manganês e zinco, posuem em sua composição os respectivos percentuais de ligação: 2,21%, 1,22%, 12,38% e 10,40%.

Abstract in English
The essential minerals participate in many vital functions in the organism, its deficiencies contribute in significant way for the morbidity and mortality in the childhood, especially in developing countries, being considered as public health problem in the whole world. Minerals presented in the form of organics complexes have been considered a good choice for these deficiencies, because it presents greater bioavailability when compared with the equivalents inorganic salts. The minerals copper, iron, manganese and zinc are essential to the organisms (human and animal), its physiological levels in accordance with the necessity contribute for the health maintence, resulting in economical benefits. In the present work it was carried through preparation and physical and chemical characterization of mineral complexes of Copper (Cu), Iron (Fe), Manganese (Mn) and Zinc (Zn) with partial hydrolysates of soy protein. The hydrolyses using the Aranzime and Alcalase enzymes had been more efficient than other enzymatic or acid hydrolyses, however only the Alcalase enzyme is approved for the manufacture of alimentary products for human consumption. Coordination between metals and the hydrolysate can be confirmed by the displacement of the ?NH2, ?aCOO- and ?sCOO- bands. The gotten copper, iron, manganese and zinc complexes, had the respective percentages of metal in its composition: 2,21%, 1,22%, 12,38% e 10,40%.
