| Abstract: | High-performance ion chromatography(HPIC) was used to analyze the hydrolization products of sodium phytate. The method was developed to determine the hydrolytic rate of sodium phytate directly. After eluted by the trinary mobile phase composed of sodium hydroxide, water and iso-propylacohol, the hydrolysates(inositol phosphates and inorganic phosphate) and the unreacted sodium phytate were eluted at different retention time. The effluents were measured by a conductivity detector. The detection results were used to calcuate the hydrolytic rate within 15 minutes. The method had been used to determine the hydrolytic rate of sodium phytate in the absence of enzyme with satisfactory result. |
