Tocopherol Content of Human Milk and of Cows’ Milk Products used for Infant Feeding

Abstract
The tocopherol content of a series of human milk samples representing various donors and stages of lactation was 0.10 to 0.48 mg/100 ml of milk, with a mean of 0.24 mg/100 ml, or about 80 µg/gm of fat. Tocopherol values did not vary with stage of lactation (third through 37th week) but were correlated with the fat content of the milk. No loss of tocopherol occurred on pasteurizing human milk. Evaporated cows' milk and samples of whole milk powder contained 23 to 40 µg of tocopherol/gm of fat. Proprietary infant foods contained 29 to 171 µg of α-tocopherol/gm of fat.
