摘要
植酸是所有植物种子的成分之一。植酸通常以混合态的Ca-Mg-K盐(即菲丁,Phytin)的形式存在于种子的不同部位。植酸的应用非常广泛。植酸的生产方法有两种:提取法与合成法。提取法制取植酸主要以农产品加工副产物如脱脂米糠、玉米浸渍水等为原料经分离、除杂、中和等工序制取;合成法主要是以非植酸化合物为原料(如六羟基苯、淀粉等)通过化学反应制得。目前合成法制取植酸的费用远远高于提取法制取植酸,所以一般采用提取法制取植酸。本文论述了现有提取法制取植酸的研究现状,并对现有生产工艺进行了分析,指出了今后提取法制取植酸的发展方向。
Phytic acid is one ingredient of all plant seeds and exists in different positions of seeds in the form of mixed state of Ca-Mg-K （i.e. phytin）.Phytic acid can be used in many fields. There are two methods to produce phytic acid, extractive and synthesis method. In extractive method, the byproducts in farm product processing such as defatted rice bran and corn-soaking water are used as raw materials, and through separation, removal impurities and neutralization processes to produce phytic acid. In synthesis method, the non-phytic acids such as hexahydroxy-benzene and starch are passed through chemical reactions to produce phytic acid. At present, the cost of synthesis method is far higher than that of extractive method, so the extractive method is commonly used to produce phytic acid. In this paper, the recent progress of preparing phytic acid with extractive method is summarized, and the productive processes are analyzed, which points out the development trend of preparing phytic acid.
