Four pearl millet cultivars of two different species--Kordofani and Ugandi (Pennisetum typhoideum) and Madelkawaya and Shambat (Pennisetum glaucum)--were germinated for 6 days. The germinated grains were dried and milled. Phytic acid and polyphenol contents and hydrochloric acid (HCl) extractability of minerals from the malt flours were determined at intervals of 2 days during germination. Phytic acid and polyphenol contents decreased significantly (P <0.01) with an increase in germination time, with a concomitant increase in HCl extractable minerals. However, the major mineral content was significantly decreased while that of trace minerals was increased with germination time. When the grains were germinated for 6 days, Madelkawaya had higher extractable calcium while Ugandi had higher extractable phosphorus, whereas iron and manganese recorded high levels in Shambat and Madelkawaya, respectively. There was good correlation between antinutritional factors reduction and the increment in extractable minerals with germination time.
对两个不同品种的四个珍珠粟品种——科尔多法尼和乌干迪（黍稷）以及马德卡瓦亚和尚巴特（非洲狼尾草）进行了6天的发芽处理。将发芽的谷粒干燥并研磨。在发芽过程中每隔2天测定麦芽粉中的植酸和多酚含量以及矿物质的盐酸（HCl）提取率。随着发芽时间的增加，植酸和多酚含量显著降低（P<0.01），同时盐酸可提取矿物质含量相应增加。然而，主要矿物质含量随着发芽时间显著降低，而微量元素含量则增加。当谷粒发芽6天时，马德卡瓦亚的可提取钙含量较高，而乌干迪的可提取磷含量较高，而铁和锰分别在尚巴特和马德卡瓦亚中含量较高。抗营养因子的减少与发芽时间导致的可提取矿物质增加之间存在良好的相关性。
