Soy Bean (Vegetable) Milk in Infant Feeding

Soya Bean Flour with Dried Milk: A Cheap and Efficient Substitute for Breast Milk

“…As cow's milk contains, say, twice as much sodium and chlorine as breast milk (Schall and Heisler, 1917), a mixture of equal parts of dried cow's milk and soyolk would presumably supply ample of these substances for the infant's needs. (Rittinger and Dembo, 1932;Bailey, Capen and Le Clerc, 1935;Horvath, 1938). One author states that there is as much as 9 per cent.…”

“…(c) 'Wet grinding' of the bean has been used by Chinese physicians on a small scale and by some American physicians (Tso, 1928 ;Guy and Yeh, 1938a;Rittinger and Dembo, 1932). This method, it is said, ' brings a certain amount of the protein into fine suspension and leaves the cellulose in the bulky residue which is filtered off' (Guy and Yeh, 1938a).…”

“…An attempt was made in the first instance to incorporate soyolk in fluid milk and then dry the mixture, but as the heat caused chemical changes in the soyolk this method was discarded in favour of mechanical mixing of the two powders. Since soya flour contains less calcium than phosphorus, most workers using soya flour for infant feeding have added a calcium salt in order to augment the calcium intake (Tso, Yee and Chen, 1928 ;Hill and Stuart, 1929Chang and Tso, 1931: Rittinger and Dembo, 1932Steams, 1933 Rittinger, Dembo andTorrey, 1935;Guy and Yeh, 1938 a, b). Sodium and chlorine content are not given in this table, but these also are low compared with dried milk, and have usually been added to 'soya-milk' for infants.…”

“…Estimates of the sugar content vary (Rittinger and Dembo, 1932;Bailey, Capen and Le Clerc, 1935;Horvath, 1938). One author states that there is as much as 9 per cent.…”

“…The composition of soya bean fat is discussed by Rittinger and Dembo (1932). They say that it is liquid at room temperature and contains a high percentage of unsaturated acids.…”
