Butter may or may not lose vitamin D over time. I don't know of any
specific tests on that point. However, irridating foods with ultraviolet
light to modify the natural sterols in food, particularly milk, fish and
eggs, to allow the liver to convert the vitamin D in them more easily is a
fact. Irridating people directly causes the body to produce vitamin D.
Harry Steenbock patented the irridation processes beginning in 1923. The
patents were revoked in 1946 on the basis they were a discovery rather than
Vitamin D was isolated by E.V. McCollum in 1922. If there was any
relationship between irridating food and rickets prior to that it would be
on the basis of observed reaction rather than understanding of the
underlying principlea. I would expect an observation of a correlation
between irridated butter and preventing or easing rickets would appear in
the observer's writings.
