The vitamin D content of many Australian game products is unknown. These foods are potential sources of vitamin D for remote-dwelling Aboriginal and Torres Strait Islander people, of whom 39% are vitamin D deficient (serum 25-hydroxyvitamin D (25(OH)D) concentrations < 50 nmol/L). Vitamin D, 25(OH)D, vitamin D and 25(OH)D were measured by liquid chromatography-triple quadrupole mass spectrometry (LC-QQQ) in raw meat (camel, crocodile, emu, kangaroo), emu eggs and emu oil. Vitamin D (range, 0.5-14.5 μg/100 g) was found in all products except camel and kangaroo. All samples except kangaroo contained 25(OH)D; some camel samples contained relatively high concentrations (range, 0.4-5.2 μg/100 g). Vitamin D was found in emu products and some kangaroo samples. We detected trace amounts of 25(OH)D in some camel and kangaroo samples. This study provides valuable insight into foods with a paucity of data on vitamin D content, showing that some are potentially useful sources of vitamin D.
许多澳大利亚野味产品的维生素D含量未知。这些食物是偏远地区居住的原住民和托雷斯海峡岛民获取维生素D的潜在来源，其中39%的人维生素D缺乏（血清25-羟基维生素D（25(OH)D）浓度<50 nmol/L）。采用液相色谱-三重四极杆质谱法（LC-QQQ）测定了生肉（骆驼肉、鳄鱼肉、鸸鹋肉、袋鼠肉）、鸸鹋蛋和鸸鹋油中的维生素D、25(OH)D、维生素D和25(OH)D。除骆驼肉和袋鼠肉外，所有产品中均检测到维生素D（范围为0.5-14.5μg/100g）。除袋鼠肉外，所有样本均含有25(OH)D；一些骆驼肉样本中含量相对较高（范围为0.4-5.2μg/100g）。在鸸鹋产品和一些袋鼠肉样本中发现了维生素D。我们在一些骆驼肉和袋鼠肉样本中检测到痕量的25(OH)D。这项研究为维生素D含量数据匮乏的食物提供了有价值的见解，表明其中一些可能是维生素D的有用来源。
