Standardized method based on extraction, filtration, and gas chromatography (GC) was developed for propylene glycol analysis to set hygienic norm of safety measure for foods under governmental control. Various columns were tested for propylene glycol analysis by GC with flame ionization detector. Known amount of propylene glycol was spiked into wheat flour dough and analyzed by developed method. Results showed 101.60% recovery rate for propylene glycol with HP-5 column. Reproducibility test of standards recorded 0.30 for standard variation and 0.42% for relative variation.
