To the Editor: The article by Dr. Helen J. Ossofsky on "Infantile Scurvy" (Amer J Dis Child 109:173 [Feb] 1965) is certainly a timely warning to us all. Unfortunately, the concentration of ascorbic acid in fresh orange juice is given as 9.5 mg/cc, which must be a printer's error. According to the Agricultural Handbook No. 8 (revised in 1963), among other sources, the average ascorbic acid concentration of all commercial varieties of fresh orange juice is 50 mg per 100 gm, or 0.5 mg/cc. I am concerned that physicians will be led to believe that orange juice is even more concentrated than it really is. Two ounces of the undiluted juice are necessary to meet the recommended dietary allowance1 of 30 mg daily for this age group.
