| Abstract: | A high performance liquid chromatography was used to determine the amount of lactic acid in maize soaking water.The column was Spherisorb NH2 column.The mobile phase was aqueous solution of 0.1% phosphoric acid. The flow rater was 1.0mL/min with a detecting wavelength of 214nm.It took about 10min to analyze a sample. The relative standard deviation was 1.1%,and the recovery was between 95% to 100.5%. It was a simple and rapid method. |
