The study was carried out keeping in view the recently emerging concern of adulteration of natural honey on the honey markets. This study intended to investigate honey adulteration detection using physical and chemical composition to achieve a foreign component (a marker) that is present in the honey that confirms either the adulteration or authenticity of the honey. The technique was evaluated on honey samples that were 5-50% adulterated with various common adulterants in Ethiopia. Preliminary quick tests and characterization of physicochemical and antioxidant properties were tested as alternative analytical approaches for honey adulteration detection. Preliminary quick test methods were used to detect adulterated honey, but these methods were found specific to adulterant materials. The proline and pH levels decreased as molasses, sugar, and banana adulterants increased, while increased as melted candy and shebeb adulterants increased. Moisture content decreased as sugar, melted candy, and shebeb adulterants were increased, while decreased as molasses and banana adulterants increased. HMF content increased as molasses, melted candy, and shebeb adulterants were increased. The sugar compositions are key differential criteria to detect the adulteration of honey with sugar. Based on their physical characteristics, PCA demonstrated a considerable difference between samples of pure and contaminated honey. In conclusion, it was observed that honey adulteration was detected based on significant deviations of physicochemical and biochemical components from expected values in the concentration of naturally occurring components. This study successfully demonstrated a method to rapidly and accurately classify and authenticate honey. Accordingly, it is recommended that frequent training for stakeholders on adulteration detection methods should be carried out to avoid adulteration of honey from the markets.
这项研究是鉴于蜂蜜市场上近期出现的天然蜂蜜掺假问题而开展的。本研究旨在利用物理和化学成分来调查蜂蜜掺假检测情况,以找出蜂蜜中存在的外来成分(一种标志物),从而确认蜂蜜是否掺假或是否为真品。该技术在埃塞俄比亚用各种常见掺假物掺假5%-50%的蜂蜜样本上进行了评估。对物理化学和抗氧化特性的初步快速测试及表征作为蜂蜜掺假检测的替代分析方法进行了测试。初步快速测试方法用于检测掺假蜂蜜,但发现这些方法对掺假物质具有特异性。随着糖蜜、糖和香蕉掺假物增加,脯氨酸和pH值水平下降,而随着融化糖果和舍贝布掺假物增加则上升。随着糖、融化糖果和舍贝布掺假物增加,水分含量下降,而随着糖蜜和香蕉掺假物增加则下降。随着糖蜜、融化糖果和舍贝布掺假物增加,羟甲基糠醛含量上升。糖的成分是检测蜂蜜是否被糖掺假的关键鉴别标准。基于其物理特性,主成分分析表明纯蜂蜜样本和受污染蜂蜜样本之间存在显著差异。总之,观察到基于物理化学和生化成分与天然存在成分浓度预期值的显著偏差可检测出蜂蜜掺假。本研究成功展示了一种快速准确地对蜂蜜进行分类和鉴定的方法。因此,建议对利益相关者进行关于掺假检测方法的频繁培训,以避免市场上的蜂蜜掺假。
