The demand for accurate and rapid quality inspection of agricultural and food products has progressively increased since it is one of the important key attributes in determining consumer preference. In this sense, electronic nose (e-nose) devices capable of capturing a “smellprint” of food products, combined to pattern recognition tools are advantageous for the discrimination of similar complex mixtures. The design of the sensing units composing the e-nose requires a judicious choice of materials with distinct selectivity and specificity for achieving outstanding performance. The present work reports on the development of an e-nose based on nanocomposites obtained by the combination of ZnO, In2O3, and ZnO/In2O3 nanoparticles with polypyrrole and poly(styrenesulfonate). The sensor array was composed by six sensing units, which were exposed to 17 coffee samples. The coffee samples were successfully discriminated by quality level with the aid of principal components analysis and Euclidian distances by dendrograms. Therefore, the sensor array made with nanocomposites is promising as an alternative tool for monitoring the quality and classification of coffee samples.

基于纳米复合材料的化学电阻电子鼻及其在咖啡分析中的应用
由于农产品和食品是决定消费者偏好的重要关键属性之一，因此对农产品和食品的准确和快速质量检验的需求逐渐增加。从这个意义上说，能够捕捉食品“气味”的电子鼻（e-nose）设备与模式识别工具相结合，有利于区分类似的复杂混合物。构成电子鼻的传感单元的设计需要明智地选择具有独特选择性和特异性的材料，以实现出色的性能。目前的工作报告了基于 ZnO、In 2 O 3和 ZnO/In 2 O 3组合获得的纳米复合材料的电子鼻的开发具有聚吡咯和聚（苯乙烯磺酸盐）的纳米颗粒。传感器阵列由六个传感单元组成，暴露于 17 个咖啡样品。借助主成分分析和树状图的欧几里得距离，咖啡样品成功地按质量水平进行了区分。因此，由纳米复合材料制成的传感器阵列有望成为监测咖啡样品质量和分类的替代工具。
