从麦麸中提取菲汀的工艺条件优化

研究了从麦麸提取菲汀的工艺条件,并对菲汀含量进行了检验。通过正交实验得到优化实验条件为初始pH值2.0,60℃水浴浸泡6h。通过二次浸泡并进行摇床动态浸泡方式,改进了传统的一次、静态浸泡的方式,从而大幅度提高了菲汀的提取率。另外,采用铁盐法进行菲汀含量测定提取效果。该工艺操作简便,可以降低原料消耗,提高废渣质量,减少废水排放量。

Condition optimization study of extract phytin from bran

We investigate the process of extracting phytic acid from bran, and check the content of phytic acid. The best condition is determined through orthogonal experiment: initial pH is 2.0; bran soaked at 60?℃ for 6 hours. We improve the traditional single static soaking by twice and dynamic soaking in rocking bed. The extraction rate is increased significantly. The content of phytic is determined with iron-salt technique to identify the extracting results. This technique is easy to operate, decreases raw material expense, elevates residue quality, and cuts down waste water.
