Unfortunately, the supply of this most valuable of foods is limited and difficult to increase; its cost of production places it beyond the reach of most impoverished people and the problems involved in protecting it from contamination remain an important barrier to its use in primitive environments. In recent years considerable effort is being devoted to the study of possible substitutes for milk protein, many of them
