提出了一种利用气味传感系统电子记录多种成分混合气味的新算法。由于人类对气味的印象主要取决于关键组分的种类，而不是准确的混合物组成，因此气味近似于几种组分的组合。此外，还建立了探索多组分组合气味近似配方的有效方法。然后，使用所提出的方法记录苹果香精的配方，并通过人体感官测试进行评价。结果，发现用多达八种组分近似的气味接近于目标苹果风味。此外，它被证实，QCM（石英晶体微天平）气味传感器阵列的响应模式是一个很好的指标，通过人类嗅觉检测到的气味。该方法有利于实现多气味成分的气味记录仪。
A new algorithm to electronically record an odor composed of the mixture of many components using the odor sensing system was proposed. Since the human impression on the odor mostly depends on the kinds of key components rather than the accurate mixture composition, the odor was approximated with the combination of several components. Moreover, the efficient method to explore the recipe for the odor approximation with the combination of many components was established. Then, the recipe of an apple flavor was recorded using the proposed method and was evaluated by the human sensory test. As a result, it was found that the odor approximated with up to eight components was close to the target apple flavor. Furthermore, it was confirmed that the response pattern of the QCM (quartz crystal microbalance) odor sensor array was a good indicator of the odors detected by human olfaction. The proposed method was useful to realize the odor recorder with many odor components.
