By feeding commercial bees with bee food that has high fructose corn syrup, the honey they produce has those chemicals in it.
Interpretive Summary: The composition of high fructose corn syrups (HFCS) from commercial manufacturers as well as from beekeepers was characterized by GC-MS. Sucrose syrups (SS) were also included in this work for comparison. We found complex carbohydrates, including Fructosyl-fructoses and fructosyl-glucoses were detected. The toxic degredation by product, Hyudroxymethylfurfural (HMF) content of the samples supplied by beekeepers was 64.61 ppm (plus or minus 16.92 ppm) above the 40 ppm that is toxic. The honey made from HFCS and SS was also analyzed and Fructosyl-fructose were detected mostly in honeys from HFCS, which was notably different from those honeys coming from free-flying bees or bees fed with SS.
