Uses of soy protein in mixed protein systems to meet nutritional needs

Abstract

Soya products can be introduced into animal protein food systems to supplement animal protein. This can serve to increase the total protein available to target populations. Nutritional studies have demonstrated that mixtures of soya protein and meat or soya protein and fish are of a biological quality similar to that of meat or fish protein when fed alone. Soya products also can be used in mixed protein systems with vegetable proteins to complement amino acids. Many studies with human subjects have demonstrated the utility of soya products in a variety of soya-cereal foods that can serve as the major source of protein for infants and children.

Avaliação da qualidade protéica de dois formulados em pó, à base de soja enriquecidos com zinco, selênio e magnésio para utilização em nutrição enteral

“…Na Tabela 5, encontram-se os valores médios para NPR, NPU e D. [7], MO-RAIS [13], MORAIS & SILVA [14]; PINOTTI [19] segundo os quais a mistura de proteína animal com proteína de soja forma dietas de alta qualidade protéica resultando em maior benefício no desempenho nutricional da proteína de soja. Em razão do fato de a soja ser deficiente em aminoácidos sulfurados, ela apresenta qualidade protéica superior ao ser complementada ou suplementada com uma fonte protéica que contenha teores consideráveis desses aminoácidos, como as proteínas animais.…”

Functional and Edible Uses of Soy Protein Products

“…Studies with young men using beef, fish, and 50:50 mixtures of beef, fish, or milk and isolate showed that the values for the 3 animal‐soy protein mixtures equaled those of the all‐beef or fish controls. These studies show that soy proteins are nutritionally excellent when used with high‐quality animal proteins in the diet (Scrimshaw and Young 1979; Hopkins and Steinke 1981).…”
