The quality of new sources of protein and their suitability for weanlings and young children.

A number of formulated protein-rich mixtures have been developed with the objective of preventing protein deficiency in vulnerable population groups, particularly in weanlings and children of pre-school in the developing countries. This paper describes an investigation, by the nitrogen balance index method, of the protein quality of several such mixtures. The results indicate that most of the mixtures are suitable protein sources for children of pre-school age.
