澳大利亚于2009年9月开始在制作面包的小麦粉中强制添加叶酸，以改善育龄妇女的膳食叶酸状况，并有助于降低人群中神经管缺陷的发生率。本文介绍了实施强制性叶酸强化标准后目标人群和澳大利亚人口其他亚群的叶酸摄入量估计值。 2010 年 6 月/7 月，从全国各地购买了来自 7 个面包类别的 100 个样品，并单独分析了它们所含的叶酸含量。使用三重酶微生物学方法的改进来测量各个面包样品中的叶酸。叶酸分析值与国家食品消费数据一起用于估算人口从强化食品中摄入的叶酸。澳大利亚新西兰食品标准局 (FSANZ) 的定制膳食模型程序 (DIAMOND) 用于进行估算。白面包中叶酸的平均含量为 200μg/100g，这表明烘烤面包时使用了叶酸强化小麦粉。摄入量估计表明，目标群体的平均叶酸摄入量每天增加 159μg。其他人群的叶酸估计平均每日摄入量也有所增加。
Mandatory folic acid fortification of wheat flour for making bread was implemented in Australia in September 2009, to improve the dietary folate status of women of child-bearing age, and help reduce the incidence of neural tube defects in the population. This paper presents estimates of folic acid intake in the target population and other subgroups of the Australian population following implementation of the mandatory folic acid fortification standard. In June/July 2010 one hundred samples from seven bread categories were purchased from around the country and individually analysed for the amount of folic acid they contained. A modification to the triple enzyme microbiological method was used to measure folic acid in the individual bread samples. The folic acid analytical values together with national food consumption data were used to generate estimates of the population's folic acid intake from fortified foods. Food Standards Australia New Zealand's (FSANZ) custom-built dietary modelling program (DIAMOND) was used for the estimates. The mean amount of folic acid found in white bread was 200 μg/100 g which demonstrated that folic-acid-fortified wheat flour was used to bake the bread. The intake estimates indicated an increase in mean folic acid intake of 159 μg per day for the target group. Other sub-groups of the population also showed increases in estimated mean daily intake of folic acid.
