In this study, we aimed to determine the effect of the cultivar and dehulling on calcium, iron, and zinc bioaccessibilities of Australian sweet lupin (ASL). Ten ASL cultivars grown in 2011, 2012, and 2013 in Western Australia were used for the study. The bioaccessibilities of calcium, iron, and zinc in whole seed and dehulled lupin samples were determined using a dialysability method. The cultivar had significant effects on calcium, iron, and zinc contents and their bioaccessibilities. Average bioaccessibilities of 6% for calcium, 17% for iron, and 9% for zinc were found for whole seeds. Dehulled ASL had average calcium, iron, and zinc bioaccessibilities of 11%, 21%, and 12%, respectively. Compared to some other pulses, ASL had better iron bioaccessibility and poorer calcium and zinc bioaccessibilities. Dehulling increased calcium bioaccessibilities of almost all lupin cultivars. The effect of dehulling on iron and zinc bioaccessibilities depends on the ASL cultivar.
在本研究中，我们旨在确定品种和去皮处理对澳大利亚甜羽扇豆（ASL）钙、铁和锌生物可利用性的影响。使用了2011年、2012年和2013年在西澳大利亚种植的10个ASL品种进行该研究。采用透析法测定了全籽和去皮羽扇豆样品中钙、铁和锌的生物可利用性。品种对钙、铁和锌含量及其生物可利用性有显著影响。全籽的钙、铁和锌平均生物可利用性分别为6%、17%和9%。去皮ASL的钙、铁和锌平均生物可利用性分别为11%、21%和12%。与其他一些豆类相比，ASL的铁生物可利用性较好，而钙和锌生物可利用性较差。去皮提高了几乎所有羽扇豆品种的钙生物可利用性。去皮对铁和锌生物可利用性的影响取决于ASL品种。
