Abstract

Trace elements are important nutritional elements for human health. Six trace elements in Fuji apple skin and pulp were analyzed by the method of ICP-MS. The results showed that the concentrations of Ca, Mn, Fe, Se, Mo and I were 197 910, 1 623, 14 400, 2, 47 and 91 ng x g(-1) x FW in apple skin respectively; and 58 360, 281, 550, 4, 18 and 24 ng x g(-1) x FW respectively in apple pulp. The concentrations of most trace elements (Ca, Mn, Fe, Mo and I) in apple skin were several times higher than those in apple pulp, especially the concentrations of Fe, Mn and I in skin was 25.18, 4.78 and 2.79 times higher than those in pulp, except Se (2 ng x g(-1) x FW in skin and 4 ng x g(-1) x FW in pulp). So we should not peel apples before we eat them from regions where were not polluted by pesticides and heavy metals.

摘要

微量元素是对人体健康重要的营养元素。采用电感耦合等离子体质谱法（ICP-MS）分析了富士苹果果皮和果肉中的六种微量元素。结果表明，苹果果皮中钙、锰、铁、硒、钼和碘的含量分别为197 910、1 623、14 400、2、47和91 ng x g(-1) x FW；苹果果肉中分别为58 360、281、550、4、18和24 ng x g(-1) x FW。苹果果皮中大多数微量元素（钙、锰、铁、钼和碘）的含量比果肉中高几倍，尤其是果皮中铁、锰和碘的含量分别比果肉中高25.18、4.78和2.79倍，硒除外（果皮中为2 ng x g(-1) x FW，果肉中为4 ng x g(-1) x FW）。因此，对于来自未受农药和重金属污染地区的苹果，我们在食用前不应削皮。
