Since a variety of smells can be made by blending multiple odor components, an odor recorder can reproduce smells as well as record them. Although recordable range of odor has been so far limited, this work enhances that range using mass spectrometer without GC. We proposed the algorithm to select appropriate odor components among huge number of candidates. In the simulation, the recipe was correctly obtained using odor components selected among 10,000 candidates. In the experiment, the flavors of apple, peach and strawberry were successfully blended using components selected among 82 candidates. Finally the similarity between target and blended ones was confirmed by sensory test.
