The study analyzed stable isotope composition (carbon, nitrogen, oxygen) of Bangladesh origin monofloral and multifloral honey for the first time to identify the C-4plant sugar adulteration, botanical and geographical differentiation. The C-4 sugar content (11.90 to 86.61%) using carbon isotope values of whole honey and protein extractidentified18% adulterated honeys.Whereas 82% honey have been detected as authentic with the δC ranges from -24.86 to -29.26‰ and the C-4 sugar values ranges from -6.75 to 5.67%. The chemometric approach using carbon and nitrogen isotopesvalues revealed discrimination among floral types of Bangladeshi authentic honeys indicating the influence of botanical source on isotopic composition. Canonical discriminant analysis (CDA) of C and N isotopes showed geographic distinction among Bangladeshi and overseas origin honeys. It is notable that the black seed honeys were correctly classified with the CDA analysis representing this type as unique Bangladesh brand as New Zealand manuka honey.
本研究首次分析了源自孟加拉国的单花蜜和百花蜜的稳定同位素组成（碳、氮、氧），以识别 C-4 植物糖的掺假、植物学和地理差异。利用整蜜和蛋白质提取物的碳同位素值，检测到 18%的掺假蜂蜜中含有 C-4 糖（11.90 至 86.61%）。而 82%的蜂蜜则被检测为纯正，其 δC 范围为-24.86 至-29.26‰，C-4 糖值范围为-6.75 至 5.67%。利用碳和氮同位素值的化学计量方法，可以在孟加拉国纯正蜂蜜的花卉类型之间进行区分，表明植物来源对同位素组成的影响。碳和氮同位素的典范判别分析（CDA）显示了孟加拉国和海外原产蜂蜜之间的地理差异。值得注意的是，黑种子蜂蜜通过 CDA 分析被正确分类，代表了这种独特的孟加拉国品牌，就像新西兰麦卢卡蜂蜜一样。
