§ 51. Mr. Leach
asked the Minister of Health whether he is aware that it is the practice of manufacturers of margarine to add cod-liver oil or other oil from fish livers, and to treat with ultra-violet rays, 536 or by other means artificially to vitaminise the margarine synthetically under the claim that its food value is then equal or superior to that of summer butter; and whether any investigation has been made by the experts of his Department for the information of the public as to whether such claims are valid?
§ Sir K. Wood
I am aware that vitamins are added artificially to some brands of margarine. The answer to the last part of the question is in the negative, but I have no reason to doubt that it is possible to make margarine the equivalent of butter in vitamin content.
