Study of odor recorder for recording recipe of orange flavor

The smell reproduction technique in addition to that for vision and hearing will be useful in the fields of virtual environments, games and e-commerce. In this study, citrus flavors were electronically recorded using "odor recorder" composed of quartz crystal microbalance odor sensors. First, an artificial orange flavor composed of 14 constituents was successfully recorded with its approximated recipe of 3 odor components. The human sensory test revealed that the reproduced odor was close to the target odor for the human olfaction. Next, we tried to record natural smells from citrus essential oils. The mixture smells of two essential oils were successfully recorded using the odor recorder.
