The sugar profile in honey can be used as a fingerprint to confirm the authenticity or reveal the adulteration of the product by sweetener addition. In this work, we have accurately determined the profile of 20 minor saccharides in a set of 46 European acacia honeys using a recently proposed NMR approach based on the CSSF-TOCSY experiment. Comparison of this reference profile with the sugar composition of several Chinese honey samples of the same declared botanical origin has revealed important differences. A detailed analysis of the saccharide profile of these Chinese honeys suggests product adulteration by overfeeding bee colonies with industrial sugars syrups during the main nectar flow period.
蜂蜜中的糖谱可以用作指纹，以确认产品的真实性或揭示通过添加甜味剂进行的掺假。在这项工作中，我们使用最近提出的基于 CSSF-TOCSY 实验的 NMR 方法，准确地确定了 46 种欧洲金合欢蜂蜜中 20 种微量糖的图谱。将此参考图谱与同一宣称植物来源的几种中国蜂蜜样本的糖组成进行比较，揭示了重要差异。对这些中国蜂蜜的糖谱进行详细分析表明，在主要花蜜流期间，通过过度喂养蜜蜂殖民地工业糖糖浆来对产品进行掺假。
