The purpose of this study was to develop the simultaneous analytical method for vitamin A and E in foods and functional food and to evaluate the applicability into commercial products in Korea market. The developed analytical method for vitamin A and E was standardized by detailedly describing the conditions of saponification in preparation process based on the international certified test methods. The simultaneous analytical conditions of vitamin A and E were 325 nm, 298 nm, respectively, using liquid chromatography UV detector. The validity of the method was satisfactory by performing validation (linearity, LOD, LOQ, accuracy, precision and interlaboratory cross-check) according to MFDS guideline. The established method was applied in sample including cereals, infant formula and health functional foods, as results of analysis, these were suitable to the standard specification, respectively. Thus, this study is available as standard method for various foods and health functional foods containing vitamin A, E.
