%X A method of separation and quantitation of monoester, diester and triester in food additive sucrose fatty acid esters by TLC with dual-wavelength TLC scanner in the sawtooth scanning mode is described. The detective wavelength was 530 nm and the reference wavelength was 700 nm. A mixture of chloroform, methanol, acetic acid and water (80:10:8:1, V/V) was used as mobile phase. The calibration curve was linear over a range from 4 micrograms to 60 micrograms with correlation coefficients of 0.9949-0.9980. The average recoveries were 96.45%-98.73% (n = 3, RSD = 2.7%-3.2%). This method is accurate, simple and dependable, with a wide range of linearity. It has been applied to the analysis of various samples and can be used for the quality control of the food additive sucrose fatty acid ester.
