微量元素与人体健康的关系己众所周知,食品加工方法对食品中微量元素的影响正越来越引起人们的重视。皮蛋加工对蛋品中 Zn、Cu、Fe 含量的影响情况,国内尚未见公开报道。为了解蛋品中 Zn、Cu、Fe 的含量因鸭品种、生长地区、饲料等不同而可能存在的差异,用六组配对样品,每组20只蛋,均系同一只鸭在近四周内产的蛋,将每组20只蛋随机分为加工组和对照组做好标 The relationship between trace elements and human health As we all know, the impact of food processing methods on trace elements in food is drawing more and more attention. The impact of preserved egg processing on the contents of Zn, Cu and Fe in eggs is not yet reported publicly in China. In order to understand the possible differences in the content of Zn, Cu and Fe in the eggs due to different varieties, growing areas and feeds, six pairs of eggs of 20 eggs in each group were produced within the last four weeks Eggs, each group of 20 eggs were randomly divided into processing group and control group to make the standard
