Enhancement of the antirachitic and calcifying properties of milk by exposure to ultraviolet rays has raised the question as to whether or not there was a destruction of vitamin A. Data from various laboratories have been contradictory, but a review of such data shows that a wide difference in the technic of irradiation, particularly in reference to the period of exposure, was in all probability the cause of the conflicting evidence. For illustration, Titus and Hughes¹ reported the apparent destruction of vitamin A in milk after an irradiation period of several minutes, whereas Supplee and Dow² reported that there was no measurable destruction of vitamin A after an exposure period of only sixteen seconds, during which substantial antirachitic properties were imparted to the milk.

Further work on the irradiation of milk at this laboratory,³ wherein the physical characteristics of the radiant energy have been correlated with the . . . [Full Text PDF of this Article]
