Summary

The effect of mixing different sources of vegetable proteins from legumes in the preparation of infant weaning foods was investigated. Melon, cowpea and soya as sole protein sources or as a mixture were fed to 60 albino rats. A milk powder-based commercial product (Cerelac) was used as control diet. The mixture of the vegetable protein diet compared favourably with the control diet in terms of growth rate, protein efficiency ratio (PER) and net protein ratio (NPR) and also ensured optimum nitrogen content in liver, kidney and muscle tissues. In contrast the use of individual protein sources failed to support satisfactory growth and were inferior to those in animals fed with the control or mixed diets. It was thus concluded that in the developing countries an application of such a mixture of vegetable proteins may be suitable in the preparation of weaning foods.

Zusammenfassung

Das Hauptziel dieser Arbeit ist es, den Einfluß von pflanzlichem Eiweiß aus verschiedenen Hülsenfrüchten in der Ernährung von Kleinkindern aufzuzeigen.

In parallelen Versuchen wurden Proteine aus der Melone, aus Raps und Sojabohnen sowie aus einer Mischung derselben insgesamt 60 Albinoratten verfüttert, um das Wachstum und den Stickstoffmetabolismus im Gewebe zu bestimmen. Cerelac® diente als Kontrollsubstanz. Mit der Proteinmischung wurden hinsichtlich des Proteinwirkungsverhältnisses (Protein efficiency ratio, PER) und des Nettoproteinverhältnisses (net protein ratio, NPR) Ergebnisse erzielt, die gut mit der Kontrollgruppe korrelieren. Wird jedoch das jeweilige Protein allein verabreicht, sinkt die Stickstoffretention in der Zelle, und das Wachstum der Tiere ist geringer.

Deshalb sollten vor allem in Entwicklungsländern pflanzliche Eiweiße in Form von Mischungen zur Herstellung von Babynahrung eingesetzt werden.
