Determination was made of alpha-, beta-plus-gamma-, and delta-tocopherol contents of brand-name canned entrées from a supermarket and from vending machines on a college campus, of several home-prepared entrées, and of sandwiches from vending machines in Spokane, Washington. Amounts of total tocopherols in canned entrées were small, ranging from none detected to 0.66 mg. per 100 gm. food. Similar home-prepared entrées, however, contained 0.41 mg. to 1.55 mg. Tocopherols in vended sandwiches ranged from 0.05 mg. to 1.86 mg. per 100 gm. sandwich. Results are also expressed as total tocopherols per serving (I.U.). These convenience foods contribute only a small amount to the day's intake of vitamin E.
测定了来自一家超市和大学校园自动售货机的名牌罐装主菜、几份家庭自制主菜以及华盛顿州斯波坎市自动售货机出售的三明治中的α-、β+γ-和δ-生育酚含量。罐装主菜中总生育酚含量很少,每100克食物中未检测到至0.66毫克不等。然而,类似的家庭自制主菜含有0.41毫克至1.55毫克。自动售货机出售的三明治中生育酚含量为每100克三明治0.05毫克至1.86毫克。结果也以每份总生育酚(国际单位)表示。这些方便食品对每日维生素E摄入量的贡献很小。
