This study aims to measure the scent of banana juice from different brands using the electronic (e-) nose FF-2A in order to identify the characteristics, time-related changes, and the differences among them.

Methods: We standardized the scent value of banana juice measured using FF-2A and determined the absolute value in three different shops.
