This research was conducted to reduce the Protein - Energy Malnutrition (PEM) of the Sri Lankan’s children through the development of biscuits, en-riched with soyflour and to increase protein nutrient consumption in human diet. The finding of this re-search revealed that, the biscuits produced with soy flour substitution, upto 25%, were nutritionally su-perior to that of the whole wheat flour biscuits. To obtain biscuits of high nutritional and organolepic qualities, wheat flour could be substituted with 10% of soy flour. The biscuits with the preparation of 90% wheat flour and 10% soy flour could provide the needed daily nutrient requirement because these biscuits contain 9.9% protein, 20% fat and the en-ergy value of 453.6kcal. The economic impact of using wheat-soybean composite flour in the manu-facturing of biscuit would impart reduction in the volume of wheat flour importation. As biscuit con-sumption in Sri Lanka is high, wheat-soybean bis-cuit will serve as a vehicle for increasing intake of protein, fat and calories for Sri Lankan’s popula-tion.
