The high proportion of seed coat of legume lupins results in big milling lose during kernel flour production, though the seed coat could be value‐added as human food. The physicochemical and nutritional properties and antioxidant capacities of seed coats of six Australian sweet lupin cultivars grown at two locations were evaluated. Results showed that genotype, environment and their interaction were significant for seed coat percentage, proximate composition, dietary fibre content, polyphenols and antioxidant capacities. Strong correlations between seed coat lightness and polyphenol content were found. A comparison using multivariate analysis of the seed coat properties showed clear separation based on growing sites. This study indicates the enormous potential of Australian sweet lupin seed coat as an ‘antioxidant dietary fibre’ food source. The results could also benefit to breed varieties with desirable levels of nutrients and phytochemicals.

羽扇豆种皮是有前途的食品成分：物理化学，营养，抗氧化特性以及基因型和环境的影响

尽管种皮可以作为人类食品增值，但豆类羽扇豆种皮的比例很高，导致籽粒粉生产过程中损失大量制粉损失。评价了在两个地点生长的六个澳大利亚甜羽扇豆品种的种皮的理化和营养特性以及抗氧化能力。结果表明，基因型，环境及其相互作用对种皮百分比，附近成分，膳食纤维含量，多酚和抗氧化能力具有重要意义。发现种皮亮度与多酚含量之间有很强的相关性。使用种皮特性的多元分析进行的比较显示，基于生长部位，分离清晰。这项研究表明，澳大利亚甜羽扇豆种皮作为“抗氧化膳食纤维”的食物来源具有巨大的潜力。
