Optimalization of the protein content of canned baby-foods based on their nutritive value

When planning canned foods the protein value Net Dietary-protein Energy percent = 8% of a 5-month old infant's requirement was considered as constant. The nutritive value required for this purpose was calculated on the basis of amino acid composition, making use of the Morup-Olesen index. Canned foods were made of two protein-containing components, of sunflower-oil and (occasionally) of starch, by computer, keeping the energy value constant, i. e. 1250 kJ, which covers half of the infant's daily requirement. The optimalization based on the protein value is illustrated by the examples of egg-potato, beef-peas and flour-beans pairs, considering the practical requirements as well.
