[摘要]
本文从120份蜂蜜样品中筛选出15份无蛋白蜂蜜样品,应用元素分析-同位素质谱联用技术(EA-IRMS)、液相色谱-同位素质谱联用技术(LC-IRMS)、液相色谱测定蜂蜜还原糖含量等检测方法,进行无蛋白蜂蜜样品真实性系统研究。发现15份无蛋白样品皆为掺假掺杂蜂蜜,无蛋白蜂蜜样品的三类典型掺假掺杂手段为:一是掺入碳-4植物源水解产物;二是掺入碳-3植物源水解产物;三是以碳-3植物源高纯度果葡糖浆造假。

[Abstract]
Fifteen honey samples which found to contain no protein from 120 specimens were further investigated by element analyzer-isotope ratio mass spectrometry, liquid chromatography-isotope ratio mass spectrometry and liquid chromatography, the protein components in the honey samples were detected. It was found that adulteration existed in all the tested fifteen samples. The samples were found to be adulterated by C-4 plant hydrolyzate, C-3 plant hydrolyzate or C-3 plant high fructose corn syrup.
