An infant cereal using banana, rice and soybean was developed to supply the needs of the Costa Rican Program for Food and Nutrition, which eventually will be introduced into the national market. This food, which uses principally nationally produced raw materials, is in the form of small flakes and can be consumed with either milk or water. The cereal was fortified with vitamins and minerals and was designed as a complementary food for weaning. The process for preparation of the cereal consists of cooking to destroy the inhibitors in the soybean to acceptable levels, gelatinization of the rice starch, inactivation of the banana enzymes, and dehydration of the mixture by drum drying to 5% MC. Optimization studies of the ingredients, using the chemical score as a nutritional index with the banana content maintained at 40%, indicated that the best complement between rice and soybean proteins was achieved in mixtures with 10.5% and 16.5% soybean dry weight. The cereal was produced on a commercial scale and an evaluation study that was done, indicated good consumer acceptance.
