Abstract
Cost estimates for a whey-soy-drink mix being tested for use as a supplementary food in beverage form for overseas preschool feeding programs are compared with prices of an instant corn-soya-milk mix for selected periods. The estimated cost of the whey-soy -drink mix was 20.30 cents per pound in August 1973 and 19.44 cents in January 1974, compared with prices of 15.05 cents and 14.80 cents for the instant corn-soya-milk mix in June 1973 and January 1974, respectively. The higher cost of the whey-soy-drink mix is due to the higher cost of raw materials and processing. Both products are less expensive than nonfat dry milk. For the whey-soy-drink mix, raw materials represented the greatest proportion of the total cost (79.6 percent in August 1973). Processing and packaging costs accounted for the balance (20.4 percent).
