The possible effect of ascorbic acid, citric acid, proteins and phytate on dialysability of Ca, Fe, Zn and Cu in soy-based infant formulas is studied, taking dialysability as a measure of the amount of element available for absorption. Different dialysis percentages for similar element contents in different formulas are found. A regression analysis was applied between Ca, Zn, Cu and Fe dialysis percentages and soy-based formula components to estimate the possible influence of the latter on the dialysability of the elements. Significant correlations were found between citric acid contents and dialysability of Zn and Fe. No correlations were found between protein, ascorbic acid and phytic acid contents and the dialysis percentages of the four minerals. However, we must to point out that the range of protein contents was narrow and the ascorbic acid: iron ratio was high in our formulas.
研究了抗坏血酸、柠檬酸、蛋白质和植酸盐对大豆基婴儿配方奶粉中钙、铁、锌和铜透析性的可能影响，将透析性作为可吸收元素量的一种衡量指标。发现不同配方中相似元素含量的透析百分比不同。对钙、锌、铜和铁的透析百分比与大豆基配方成分进行了回归分析，以估计后者对元素透析性的可能影响。发现柠檬酸含量与锌和铁的透析性之间存在显著相关性。未发现蛋白质、抗坏血酸和植酸盐含量与四种矿物质的透析百分比之间存在相关性。然而，我们必须指出，我们的配方中蛋白质含量范围较窄，且抗坏血酸与铁的比例较高。
