The nutritional goal of the school student's food is to supplement the school diet with the major nutritional elements during his time in school as required by the needs of the student body and the elements of food during the study period.
One of the best school nutrition programs used is the preparation of cereal products supported by one of the sources of available protein from various types of cereals, legumes, oil seeds and skim milk.
The aim of this study is to prepare six nutritional formulae for school students from several available cereals and legumes including (wheat, corn, barley, chickpea, rice, lentil, sesame, soybean and peanut). The gross chemical composition as well as the caloric value of all formulae, in addition to mineral composition of these formulae was estimated. The amino acid composition and fatty acid composition were studied as well.
The proportion of crude protein in the formulae ranged between 11.45 to 25.52% on a dry basis for formulae F1S, F2T, respectively. Therefore,most of the studied formulae were a rich source of protein .
The proportion of crude fat in the formulae ranged between 6.75 to 14.51%, on a dry basis for formulae F2T, F2S, respectively.
While the carbohydrates was highest 71.89% (F1T), in contrast to formula F2T which contained 54.14% of carbohydrates.
The highest caloric value (k.cal/100g dry weight) was (436.11) in formula F2S followed by formula F1S (433.92) then formula F3S (432.57) .
The studied formulae had high values for the elements calcium, magnesium, potassium and phosphorus. Concerning iron values were higher than the recommended daily allowances for students.
Data indicated that the values of essential amino acids ( threonine, isoleucine, leucine, phenylalanine and lysine) in all studied formulae were equal or higher than recommended by the (FAO/WHO/UNU ,1985).
Data revealed that all the six studied formulae had relatively high proportions of oleic and lenoleic acids. On the other hand, their contents of lenolenic were very low.
Formulae (F2S, F2T, and F3T) had the highest values of lenolenic acid (3.7, 2.2, and 1.1%) of the total fatty acids, respectively.
