Sugarcane honey (SCH) is a black syrup recognized by its excellent quality, being produced in Madeira Island using the regional sugarcane cultivars and following a traditional and peculiar manufacturing and storage processes. However, some low-quality commercial products have been labeled as SCH but do not respect its criteria, revealing the need of develop powerful strategies in order to detect and prevent adulterations. The knowledge of furanic derivatives (FDs) profile, produced during browning reactions that occurs during food processing and storage, emerged as a promising strategy in food quality and fraud prevention. Therefore, the aim of this study was to establish the FDs profiling of typical SCH produced by certified and non-certified producers, in different geographical regions (Madeira and Brazil), based on microextraction by packed sorbent (MEPS) combined with ultra-high performance liquid chromatography (UHPLC) as a useful approach to define its typicality and authenticity. These parameters are defined through the differentiation and discrimination of FDs profiles among other sugarcane-derived products using multivariate statistical analysis (ANOVA with post-hoc Tukey, principal components analysis, partial least square, linear discriminant analysis and hierarchical clustering). The results demonstrated that SCH samples from non-certified producers present the highest levels of FDs. In addition, SCH samples from Brazil present higher levels of FDs than samples from Madeira region. The obtained results revealed that the proposed approach is a valuable strategy to establish the typicality of SCH, ensuring its quality, authenticity, safety control and a useful support regarding the application of SCH from Madeira Island to EU certification.

以指纹图谱为目标的甘蔗蜂蜜真实性的化合物-一种基于色谱和统计数据的方法

甘蔗蜂蜜(SCH)是一种黑色糖浆,以其卓越的品质而著称,它是使用当地的甘蔗品种在马德拉岛上生产的,并遵循传统且特殊的制造和存储过程。但是,一些低质量的商业产品已被标记为SCH,但不遵守其标准,这表明需要开发强大的策略以检测和防止掺假。在食品加工和存储过程中发生的褐变反应过程中产生的呋喃衍生物(FDs)概况的知识,已成为食品质量和预防欺诈的一种有前途的策略。因此,本研究的目的是建立在不同地理区域(马德拉和巴西)由认证和非认证生产商生产的典型SCH的FD分布图,基于填充吸附剂(MEPS)的微萃取结合超高效液相色谱(UHPLC)的方法,是确定其典型性和真实性的有用方法。这些参数是通过使用多元统计分析(带有事后Tukey的ANOVA,主成分分析,偏最小二乘,线性判别分析和层次聚类)对其他甘蔗衍生产品中的FDs谱进行区分和区分来定义的。结果表明,来自非认证生产商的SCH样品显示出最高水平的FD。此外,来自巴西的SCH样品比来自马德拉地区的FD含量更高。获得的结果表明,该方法是建立SCH典型性,确保其质量,真实性,
