【摘要】 本文用动物血红蛋白（Hb）再生实验法研究黄豆中铁的相对生物利用率及促进因子对黄豆铁吸收的作用,比较了斜率比法和Hb再生效率法的优缺点。结果表明,黄豆中铁的相对生物率为76～78％,与硫酸亚铁（FeSO₄）组比较无显著差异。黄豆粉中加入抗坏血酸、瘦猪肉、半脱氨酸,均有升高Hb,促进黄豆中铁吸收的作用,相对生物利用率分别增至102％、102％、95.95％。更多还原

【Abstract】 Hemoglobin regeneration assay in rats was used to investigate the bioavailability of iron from soybean and effect of some enhancers on absorption of iron from soybean. The pros and cons on availability of iron between a slope-ratio assay and a hemoglobin regeneration efficiency in anemic rats were compared. The result showed that relative bioavailability of iron in soybean was 76 percent to 78 percent, no statistical significance was found to compare with those of FeSO4 groups. Hemoglobin and absorption of iron from soybean will be increased when asdorbic acid, meat, and cysteine were added to soybean powder, the relative bioavailability were 102%, 102%, 95.95%.更多还原
