EFFECT OF DEPHYTINIZED SOY FORMULA ON TRACE ELEMENT STATUS

在美国，大豆配方奶粉通常用于婴儿。最近 研究表明，大豆配方食品中的一种成分植酸， 从这些产品中吸收矿物质。 现在可以生产 含有脱植酸大豆蛋白分离物的大豆配方。 此外，本发明还提供了一种方法， 可获得部分水解的脱植酸大豆分离物，其可 还改善这些产品的蛋白质消化率。 在本研究中， 恒河猴幼猴从出生起就被喂食常规的大豆配方食品， 已经脱植酸或既脱植酸又脱植酸的大豆配方食品 水解配方。 婴儿随访4个月， 每月一次。 结果表明，婴儿的锌状态较低， 普通大豆配方奶粉的比例高于其他组。 然而，铜的地位， 在脱植酸配方中较低，但在脱植酸/水解配方中没有 产品 这些结果表明， 大豆配方奶粉中的蛋白质可改善婴儿的微量元素状况。

Soy formulas are commonly used for infants in the united states. Recent studies have shown that a component of soy formula, phytic acid, reduces mineral absorption from these products. It is now possible to produce soy formula with dephytinized soy protein isolate. In addition, partially hydrolyzed dephytinized soy isolate is available, which may also improve protein digestibility of these products. In this study, infant rhesus monkeys were fed from birth either regular soy formula or soy formula that had been dephytinized or both dephytinized and hydrolyzed formula. Infants were followed for 4 months and weight drawn monthly. The results show that zinc status was lower in infants fed regular soy formula than in the other groups. Copper status, however, was lower in dephytinized formula, but not in the dephytinized/hydrolyzed product. These results suggest that dephytinization and hydrolysis of proteins in soy formula improves trace element status of infants.
