In accordance with the national Appellation d'Origine Contrôlée and the European Protected Designation of Origin labels, Corsican honeys can be classified into six ranges (spring, spring maquis, honeydew maquis, chestnut grove, summer maquis and autumn maquis). Toward proposing a new and faster method for performing honey quality assessments, an headspace‐solid phase microextraction (HS‐SPME)/Gas Chromatography (GC)/GC‐Mass Spectrometry (MS) method with multivariate data analysis – principal component analysis (PCA), cluster analysis (CA), partial lest square (PLS) – was developed using 269 Corsican samples, for which the volatile compositions were established a priori. Corsican honeydew and blossom honey could be differentiated by the richness of 3‐furaldehyde in the category of “honeydew maquis”. This approach also allowed identification of chemical markers of the botanical origins of blossom honeys, including 2‐aminoacetophenone, p‐anisaldehyde, 4‐n‐propylanisole, isophorone, and isomers of lilac aldehyde. Therefore, characterization of the volatile fraction of Corsican honeys combined with chemometric analysis may be useful for detecting the nectar contribution of plant species in honeys with complex nectariferous origins.

挥发性成分是科西嘉蜂蜜的植物来源的化学标记

根据国家原产地名称和欧洲受保护的原产地标记，科西嘉蜂蜜可分为六个范围（春季，春季甜瓜，甘露甜瓜，板栗林，夏季甜瓜和秋季甜瓜）。为了提出一种新的，更快的蜂蜜质量评估方法，采用了具有多变量数据分析的顶空-固相微萃取（HS-SPME）/气相色谱（GC）/ GC-质谱（MS）方法-主成分分析（PCA） ，聚类分析（CA），局部最小二乘（PLS）–使用了269个科西嘉岛样品进行了开发，并针对这些样品先验建立了挥发性成分。科西嘉的蜜露和花蜜可以通过“蜜糖蜜”类别中3-呋喃醛的丰富度来区分。这种方法还可以鉴定开花蜂蜜的植物来源的化学标记，包括2-氨基苯乙酮，对茴香醛，4-正丙基苯甲醚，异佛尔酮和丁香醛的异构体。因此，结合化学计量学分析表征科西嘉蜂蜜的挥发性成分可能有助于检测具有复杂油桃起源的蜂蜜中植物物种的花蜜贡献。
