荠菜中植酸的提取工艺研究

Study on the Extraction Process of Phytic Acid from Shepherd’s Purse

本试验对荠菜中植酸的提取条件进行优化,并对植酸粗提物的抗氧化活性进行了探究。试验采用单因素及正交试验方法,对植酸提取的时间、温度、盐酸浓度和液料比进行研究。研究结果,荠菜中植酸提取的最优条件为提取时间100 min、温度30℃、盐酸0.010 mol·L-1、液料比8∶1,在该条件下植酸提取率达到2.36%。

In this experiment,shepherd’s purse was used as raw material to optimize the extraction conditions of phytic acid.The extraction factors of phytic acid were studied by single factor and orthogonal experiments.The results showed that extracting time was 100 min,temperature was 30℃,the concentration of hydrochloric acid was 0.010 mol·L-1,and solidliquid ratio was 8∶1 were the optimal condition of extracting phytic acid from the Shepherd’s purse,under the condition of the phytic acid extraction rate reached 2.36%.
