This study provides data on the total and haem iron contents in raw lean beef, chicken, lamb and pork meat samples. Total iron, expressed as mg/100g edible portion on fresh weight basis in raw lean beef (A-age), lamb, pork and chicken average 1.58, 1.64, 0.81 and 0.78, respectively. The haem iron content in beef (A-age), lamb, pork and chicken are 77%, 81%, 88% and 74% respectively of total iron. This has important dietary implications in calculating haem iron fractions of meat as this is higher than the common value used in the Monsen equation.
本研究提供了生瘦牛肉、鸡肉、羊肉和猪肉样本中总铁和血红素铁含量的数据。以毫克/100克可食部分计,生瘦牛肉(A龄)、羊肉、猪肉和鸡肉中基于鲜重的总铁平均分别为1.58、1.64、0.81和0.78。牛肉(A龄)、羊肉、猪肉和鸡肉中的血红素铁含量分别占总铁的77%、81%、88%和74%。这在计算肉类的血红素铁含量方面具有重要的饮食意义,因为这高于蒙森方程中常用的值。
