But odor is normally produced by a set of stimuli, and odor interactions among constituents significantly influenced their mixture\u2019s odor intensity. This study investigated the odor interaction principle in odor mixtures of aldehydes and esters, respectively. Then, a modified vector model (MVM) was proposed and it successfully demonstrated the similarity of the odor interaction pattern among odorants of the same type. Based on the regular interaction pattern, unlike a determined empirical model only fit for a specific odor mixture in conventional approaches, the MVM distinctly simplified the odor intensity prediction of odor mixtures. Furthermore, the MVM also provided a way of directly converting constituents\u2019 chemical concentrations to their mixture\u2019s odor intensity. By combining the MVM with usual data-processing algorithm of e-nose, a new e-nose system was established for an odor intensity rating. Compared with instrumental analysis and human assessor, it exhibited accuracy well in both quantitative analysis (Pearson correlation coefficient was 0.999 for individual aldehydes (n = 12), 0.996 for their binary mixtures (n = 36) and 0.990 for their ternary mixtures (n = 60)) and odor intensity assessment (Pearson correlation coefficient was 0.980 for individual aldehydes (n = 15), 0.973 for their binary mixtures (n = 24), and 0.888 for their ternary mixtures (n = 25)). Thus, the observed regular interaction pattern is considered an important foundation for accelerating extensive application of olfactory evaluation in odor pollution monitoring.<\/jats:p>","DOI":"10.3390\/s17071624","type":"journal-article","created":{"date-parts":[[2017,7,13]],"date-time":"2017-07-13T10:31:57Z","timestamp":1499941917000},"page":"1624","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":44,"title":["The Regular Interaction Pattern among Odorants of the Same Type and Its Application in Odor Intensity Assessment"],"prefix":"10.3390","volume":"17","author":[{"given":"Luchun","family":"Yan","sequence":"first","affiliation":[{"name":"School of Materials Science and Engineering, University of Science and Technology Beijing, Beijing 100083, China"}]},{"given":"Jiemin","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Chemistry and Biological Engineering, University of Science and Technology Beijing, Beijing 100083, China"}]},{"given":"Shen","family":"Jiang","sequence":"additional","affiliation":[{"name":"School of Chemistry and Biological Engineering, University of Science and Technology Beijing, Beijing 100083, China"}]},{"given":"Chuandong","family":"Wu","sequence":"additional","affiliation":[{"name":"School of Chemistry and Biological Engineering, University of Science and Technology Beijing, Beijing 100083, China"}]},{"given":"Kewei","family":"Gao","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, University of Science and Technology Beijing, Beijing 100083, China"}]}],"member":"1968","published-online":{"date-parts":[[2017,7,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"205","DOI":"10.1016\/j.atmosenv.2016.05.043","article-title":"Aromatic compound emissions from municipal solid waste landfill: Emission factors and their impact on air pollution","volume":"139","author":"Liu","year":"2016","journal-title":"Atmos.
