Abstract

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.

摘要

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。
