【摘要】 以蚕豆为研究对象,探讨了发芽过程中植酸和铁在蚕豆不同部位含量分布及变化情况。植酸随发芽时间延长含量在不断减少,发芽至第8天,子叶中植酸含量减少50%。在发芽过程中,铁含量在子叶中最高,其次是胚轴,而胚根和胚芽中含量最低。蚕豆发芽过程中铁的化学价态发生改变,其中有利于人体吸收的二价铁的比例显著增加。因此,通过发芽处理可提高蚕豆中铁的生物有效性。更多还原

【Abstract】 Phytic acid and iron content in faba bean fractions during germination are investigated.Germination is an effective approach to reducing phytic acid in cotyledon and phytic acid is removed by 50% in cotyledon of the bean on the eighth day during germination.The cotyledon has the highest content of Fe,followed by embryonic axis,radicle and plumula.During germination,some mechanisms of faba bean can lead to the changing of iron chemical forms.By this mechanism the content of soluble ferrous iron increases obviously.So germination is a good way to improve the iron bioactivity in faba bean.更多还原
