Abstract

The protein efficiency ratio (PER) and over-all nutritive value of a spraydried infant food, based on peanut protein isolate, full-fat soy flour, dextrimaltose, and hydrogenated peanut oil and fortified with DL-methionine and certain vitamins and minerals were studied with weanling albino rats. The PER of the infant food was 2.34, and that of the same fortified with DL-methionine was 2.86, compared with 3.19 for milk proteins. The over-all growth-promoting value of the food, with and without added methionine, ranged from 20.1 to 20.3 g/week and was significantly higher than that obtained for a milk food of similar composition (13.9 g/week). Similar trends were observed in the feed efficiency ratios of the two foods. 3 :1 blend of infant food and cane sugar promoted nearly the same growth (20.1-22.2 g/week) as did the infant food, which was significantly higher than that (16.1 g/week) obtained for a 3:1 blend of milk food and sugar. No significant differences were observed in the mellin liver fat content and the mean nitrogen and calcium contents of the carcasses of rats receiving infant food or milk food.
