| 摘 要： | 大豆及其加工制品用１．２％ＨＣｌ１０％Ｎａ２ＳＯ４试剂提取，１５％ＴＣＡ试剂沉淀酸性蛋白质，０．７５ｍｏｌ／ＬＮａＯＨ调节上清液ｐＨ值到６．０～６．５，用０．３％磺基水杨酸０．０３％ＦｅＣｌ３６Ｈ２Ｏ试剂比色，于可见光５００ｎｍ处检测，并用标准加入法进行定量分析。结果，测定一种样品１０次变异系数为３．３３％，７种样品回收率范围为８９．８８％～１０３．３８％，１５种样品植酸含量为０．５１％～１．９２％。

| Abstract: | Phyate in 15 kinds of soybean and its products was determined by colorimetic method with ferric chloride. CV% of one kind of sample was 3.33% (n=10).Recovery of 7 kinds of sample was 89.88%-103.38% (n=4).Phyate content of 15 kinds of sample was 0.51%-1.92%. It revealed that this method was quick, simple and relatively correct compared with Ellis method. |
