SOY BEANS AS HUMAN FOOD. 5 



Note. — The advantage of this method over the others may be sum- 

 marized as follows: — 



1. Ehmination of disagreeable flavor. 



2. Adjustment of taste. 



3. Reducing the probability of flatulence in the alimentary canal. 



4. Adaptability as a Uquid food for diabetic patients. 



The results of further investigation of the method and also of its nutri- 

 tive value are withheld for the present. 



Synthetic Toniu. 

 Toniu of very high quahty, which resembles cow's milk very closely in 

 composition, can be produced through both chemical and biological 

 means; in fact, the author has been informed that tliis end has been 

 accomphshed in one of the London chemical laboratories. The author, 

 however, doubts its practicabihty for domestic use. 



Condensed Soy Bean Milk {Condensed Toniu). '^ 



1. Add 4 grams of dipotassium phosphate and 600 grams of cane sugar 

 to 4 liters of soy bean milk. 



2. Concentrate the solution in vacuo to a very thick Uquid. 



Note. — It can be used like condensed cow's milk for the preparation 

 of chocolate, etc. It gives an agreeable taste, but has a very feeble odor 

 of raw beans. 



Evaporated Soy Bean Milk (Yuba). 



1. Boil the soy bean milk until a film is formed on the surface. 



2. Collect the film and cut it in any shape desired. 



Note. — The film consists of coagulated albuminoids and fat. It may 

 be used as an article of food, cooked in soup, etc.
