No foods are available commercially for weanling infants except a limited amount of expensive milk products in Korea. Although the majority of infants are breast-fed, when it is not possible, rice products must usually be substituted which is not sufficient in protein. Therefore, it is urgent to develop low-cost quality protein food mixtures. In order to accomplish this purpose three food mixtures (F-S-2, F-F-3 and F-P-4), consisting of rice (37∼46%), soybean (24∼40%), FPC (3∼7%), vitamins, minerals and other food additives, are developed. The food mixtures are white to light yellow in color; dispersed readily in water with water absorption index 320; viable bacterial population, less than 10⁴ per gram; sedimentation value, 63; Bostwick consistency value, 15㎝/30%; and ring test value, 23㎝/30%.
The products contain 22∼25% protein and ensure reasonably balanced essential amino acids for the requirement of infants compared with FAO provisional pattern, Rao´s maximum growth requirements and Holt´s amino acid requirements in early life. Although threonine is limiting, protein score of F-P-4 formula is 93 based on the modified FAO provisional pattern (1965).
Furthermore, a 100g of the products supplies required amounts of vitamins and minerals by the recommended daily dietary allowances for infants.
