Manufactured milk

From time to time items in newspapers predict that the dairy cow will soon become obsolete and that a bright new idea is to make milk without her help. They usually claim that the artificial milk has a higher nutritive value and more health promoting properties. Most of these write‐ups are nonsense and die a natural death but there is, in fact, an industry devoted to producing what may be loosely termed ‘manufactured milk’. But these factories still rely largely on our old friend the cow for much of their raw material.
