Australia needs accurate vitamin D food composition data to support public health initiatives. Previously, limitations in analytical methodology have precluded development of a comprehensive database. We used liquid chromatography with triple quadrupole mass spectrometry (LC-QQQ) to analyse 149 composite samples representing 98 foods (primary samples n = 896) in duplicate for vitamin D, 25-hydroxyvitamin D (25(OH)D), vitamin D, 25(OH)D. The greatest concentrations of vitamin D were found in canned salmon and a malted chocolate drink powder (fortified); chicken eggs and chicken leg meat contained the most 25(OH)D. Margarine (fortified) and chocolate contained the greatest concentrations of vitamin D, with smaller amounts found in various meat products. 25(OH)D was detected in various foods, including meats, and was quantitated in lamb liver. These data advance knowledge of dietary vitamin D in Australia and highlight the importance of analysis of these four forms of vitamin D to accurately represent the vitamin D content of food.
澳大利亚需要准确的维生素 D 食物成分数据来支持公共卫生计划。此前，分析方法的局限性阻碍了综合数据库的开发。我们使用液相色谱-三重四极杆质谱法（LC-QQQ）分析了 149 个复合样本，这些样本代表了 98 种食物（初级样本 n=896），每种食物均进行了两次重复分析，以检测维生素 D、25-羟维生素 D（25(OH)D）、维生素 D 和 25(OH)D。维生素 D 浓度最高的食物是罐装三文鱼和一种麦芽巧克力饮料粉（强化型）；鸡鸡蛋和鸡腿肉含有最多的 25(OH)D。人造黄油（强化型）和巧克力含有最高浓度的维生素 D，而各种肉类产品中的含量则较低。25(OH)D 存在于各种食物中，包括肉类，并在羊肝中进行了定量分析。这些数据增进了我们对澳大利亚饮食中维生素 D 的了解，并强调了分析这四种形式的维生素 D 以准确代表食物中维生素 D 含量的重要性。
