Abstract

Naturally occurring proteins vary widely in their nutritive value, due primarily, to variations in their essential amino acid composition in relation to the requirements of animals or humans" 2. Almost all vegetable proteins are partially deficient in one or more essential amino acids' 3. Even though the proteins of legumes and oilseeds supplement those of cereals to a significant extent, they are, nevertheless, less effective than the proteins of milk and other animal foods' 5. One way of improving the nutritive value of vegetable proteins as suggested by some workers is by supplementation of the proteins with the deficient essential amino acids'. The need for utilising oilseed meals and pulses for making up the protein deficiency in the diets of children in several economically underdeveloped countries, where protein malnutrition is widely prevalent, has been engaging the attention of nutritionists and also of international organisations'' 1°. Subrahmanyan et al9. reported that a blend of low fat groundnut flour (60 parts), Bengal gram (20 parts) and skim milk powder (20 parts) fortified with certain vitamins and calcium salts was very effective in the treatment of kwashiorkor. Scrimshaw et a1.1° r ecently reported that a protein food known as INCAP mixture 9B consisting of a mixture of corn, 29 parts, sorghum, 29 parts, cottonseed meal, 38 parts, dry torula yeast, 3 parts, calcium carbonate, 1 part and vitamin A, 10,000 I.U., was highly effective in the treatment of protein malnutrition in children. The recent report of the FAO Committee on protein requirements has emphasised the need for taking into consideration the amino acid content and nutritive value of the proteins present in the dietary for estimating human protein requirementsu. Based on the available information on the amino acid requirements of children and adults, the FAO Committee recommended a 'reference protein pattern' which could serve as a standard of comparison in assessing the quality of dietary proteins. In the present investigation, the protein efficiency ratios of certain protein blends (with and without fortification with amino acids) having amino acid compositions similar to that of FAO 'reference protein pattern' have been studied. At the same time, it was considered to be of interest to determine the PER of protein blends which would prove useful in the treatment and prevention of protein malnutrition in children in different parts of the world.
