Aroma‐active compounds can usefully be employed to trace the production areas of two citrus cultivars (‘Eureka’ lemon and ‘Huapi’ kumquat) and to evaluate their aroma quality.RESULTS‘Huapi’ kumquat peel displayed higher monoterpene and sesquiterpene compound content, whereas ‘Eureka’ lemon peel exhibited higher monoterpene and monoterpene aldehyde compound content. ‘Eureka’ lemon peel (‘Wanzhou’ cultivar) had higher nerol acetate and geraniol acetate compound content. Kumquat peel (‘Suichuan’ and ‘Rongan’ cultivars) had higher sesquiterpene content. In addition, 30 and 31 aroma‐active compounds were observed in kumquat and lemon, respectively, based on their odor activity values. Principal component analysis (PCA) and hierarchical clustering analysis (HCA) results indicated that classification for production areas based on aroma‐active compounds was useful. The selected aroma‐active compounds have been checked as aroma quality parameters that could be used with multivariate analysis to establish a model of aroma quality evaluation. Higher aroma quality values from kumquat and lemon were collected from Rongan and Wanzhou cultivars, respectively.CONCLUSIONAroma‐active compounds can be used to discriminate production areas using multivariate statistics. An objective method was established to evaluate the aroma quality of citrus fruits. ‘Huapi’ kumquat and ‘Eureka’ lemon, which had the highest aroma quality, was harvested from the Rongan and Wanzhou production areas. This was the first time that the aroma quality of citrus fruits was evaluated using multivariate analysis. © 2019 Society of Chemical Industry
