绪言植酸即肌醇六磷酸,其分子式为C_6H_(18)O_(24)P_6,它是多种饲料原料中的一种天然的抗营养成分,由于它能与许多二阶和三价阳离子如Ca~(2+)、Zn~(2+)、Mg~(2+)、Fe~(2+)、Fe~(3+)结合而形成不溶性的复合物,使这些营养元素不能被单胃动物所吸收,同时植酸还能与蛋白质结合,影响动物蛋白质的利用,因此研究快速测定植酸的方法,有着重要的现实意义。据文献报道,测定植酸的方法有铁沉淀法,阴离子交换法,高压液相色谱法,核磁共振法和酶法等,以往的方法都需要费时的
Phytic acid phytate phytic acid, its molecular formula C_6H_ (18) O_ (24) P_6, which is a variety of feed ingredients of a natural anti-nutritional ingredients, because it can with many second and trivalent cation such as Ca2 +, Zn2 +, Mg2 +, Fe2 +, Fe3 + to form insoluble compounds, so that these nutrients can not be monogastric animals The absorption of phytic acid also binds with proteins and affects the utilization of animal proteins. Therefore, it is of great practical significance to study the rapid determination of phytic acid. It has been reported in the literature that methods of determining phytic acid include iron precipitation, anion exchange, high pressure liquid chromatography, nuclear magnetic resonance and enzymatic methods. The conventional methods require time-consuming
