Abstract

The controversial question of whether optical rotation data can be used to distinguish floral from honeydew honey was investigated. Specific optical rotation angles were determined for 41 honey samples, including floral, honeydew, and adulterated honey, indicating that moderate to high positive optical rotation angles were found for all adulterated samples measured. A strong correlation between the sugar profile and the specific optical rotation angle of honey was confirmed, and a method based on C NMR metabolomics was proposed to calculate specific optical rotation angles with good correlation with the experimental values. The results indicate that optical rotation is not a reliable method for distinguishing the origin of honey but could indicate adulteration.

摘要

是否可以利用旋光度数据来区分花蜜蜜和甘露蜜这一颇具争议的问题已得到调查。已针对包括花蜜蜜、甘露蜜和掺假蜜在内的 41 个蜂蜜样本确定了特定的旋光度，表明所测的所有掺假样本的旋光度均处于中高正值。确认了蜂蜜的糖分布与特定旋光度之间具有很强的相关性，并提出了一种基于 C NMR 代谢组学的方法，该方法可计算出与实验值具有良好相关性的特定旋光度。结果表明，旋光度不是区分蜂蜜来源的可靠方法，但可表明掺假情况。
