M. Luckiesh (Director, Lighting Research Laboratory National Lamp Works of General Electric Co.) & A.J. Pacini (Director, Department of Biophysical Research, Victor X-ray Corporation of General Electric Co.) wrote in 1926 …
“Curiously enough certain preservatives such as benzoate derivatives apparently destroy the ‘active’ qualities of irradiated fats like cholesterol and if this action is found to hold good at all times, the preservation of foodstuffs by means of substances such as benzoic acid, sodium benzoate, salicylic acid and salicylates would probably require new study and revision so as to preclude any interference with the natural properties that vegetables grown in sunlight should normally possess.”
