This study proposed an approach using Nafion as a binder to immobilize poly (diallyldimethylammoni-umchloride) (PDDAC) on a common capillary to prepare PDDAC-Nafion coated fiber. The adsorption of target molecule (2-acetyl-1-pyrroline, 2-AP ) in rice on the fiber was tracked by gas chromatography. We investigated and optimized the experimental parameters related to extraction efficiency such as desorption temperature, des-orption time and extraction time. The linear regression of 2-AP is found to be from 0.50 to 8.00 ng·mL-1,and the detection limit 0.10 ng·mL-1. This proposed method was successfully applied to the determination of 2-AP in rice samples.
