%X ABSTRACT The ability to readily determine the composition of brown rice vinegar is important for quality assurance purposes. To that end, solid每phase microextraction (SPME)每Arrow method was optimized for the determination of volatile organic compounds (VOCs) from brown rice vinegar. Compared to traditional SPME fibers, SPME每Arrow has a larger sorbent-phase volume and is more durable. The SPME每Arrow conditions, including coating material, extraction temperature, extraction time, and NaCl concentration, were examined, which led to optimum extraction conditions that include: carboxen/polydimethylsiloxane (CAR/PDMS) fiber, 50∼C, 30 min of SPME每Arrow, and 0% NaCl (i.e., no added NaCl). The developed method was compared to an optimized method based on conventional SPME. Twelve major VOCs, including acetates, alcohols, aldehydes, acids, and furan derivatives, were extracted by SPME每Arrow, while only seven VOCs were extracted using the traditional SPME. Moreover, SPME每Arrow extracted more 1.3每2 times more VOCs than SPME. Hence, the CAR/PDMS SPME每Arrow fiber is suitable for acquiring VOC profiles from brown rice vinegar
