【摘要】 为了评价黑米糠中铁的可利用程度,本文用Hb恢复法研完了黑米糠铁的相对生物利用率（RBA）。将复制成功的贫血大鼠分为甲、乙、丙、丁和戊五组,在低铁基础饲料基础上,甲组加FeSO₄铁;乙组加糠;丙组加糠和Vc,丁组加糠和熟瘦猪肉,戊组不加为阴性对照组。结果:甲、乙、丙、丁组饲料铁转化入Hb的效率依次为59%、33%、33%和39%,RBA依次为100%,56%、56%和66%。更多还原

【Abstract】 The bran of black rice contains 210～480 ppm iron, 50～70ppm zinc and 14.1% protein. In order to evaluate the bioavailability of bran iron, its relative biological availability (RBA) has been studied by means of the hemoglobin regeneration technique in anemic rats. All the rats were divided into five groups, the low-iron basal diet was supplemented with 23ppm Fe of ferrous sulfate in group A, 11.5% bran in group B, 11.5% bran plus 0.2% Vc in group C, 11.5% bran plus 2.3% cooked lean pork in group D and nothing in group E as the negative control The efficiencies of converting iron from the diet of group A, B, C, D into hemoglobin were 59%, 33%, 33% and 39% respectively and the relative biological availabilities were 100%, 56%, 56% and 66% respectively.更多还原
