[72] The best substitute for the homogenizer is found in an electric mixer; a formula prepared with a fat other than cream can be made by means of this mixer to approximate very closely that of homogenized milk. [73] There are a number of pasteurizers on the market; one sold by the Walker Gordon Laboratory and one designed by Dr. R. G. Freeman of New York are both satisfactory. [74] Method suggested by Morse and Talbot, "Diseases of Nutrition and Infant Feeding," pp. 234-235. [75] "Diseases of Nutrition and Infant Feeding," pp. 225 and 226, by Morse and Talbot. [76] One-half tbs. barley flour may be cooked in the water used as diluent; it should be boiled 20 minutes, strained and cooled before adding to formula. [77] When babies are fed upon pasteurized, sterilized, or dried milk it is advisable to use orange or prune juice earlier than the seventh month. Dr. Hess suggests the use of canned tomato juice as substitute for orange juice. [78] "Diseases of Nutrition and Infant Feeding," p. 236, by Morse and Talbot.
