Three types of infant food were experimentally prepared based on the average caloric requirement for Koreans : Formula A, with 1/3 RDA for 4-6 month, formula B, with 1/2 RDA for 7 - 9 month, and formula C, with 2/ 3 RDA for 10 -12 month old infants. Into each formula was added approximately 50 % of rice. Analysis of the nutritive values on these formulae showed no deviance from the expected values in case of general nutrients while the percent of essential amino acids in protein was much higher except methionine. Since iron content was found to be below the half of the expected values, a sufficient amount of iron as required in RDA should be additionally supplied, for example, in iron drops.
The infant preference test on each formula showed much favorable acceptability :50 % of them responded as moderate, 33.3 % as favorable, 12.5 % as disliking, and 4.2 % as disgusting. The test also showed no noticeable change in both feces and appetite.
