Hi all,
Just saw this published. The authors are concerned with analyzing
the chemical composition of the honey made by free-flying bees vs.
those that are fed HFCS and kept to a confined area so as not to
forage. They do not look at bee health, or the honey made by free-
flying bees following HFCS feeding... Not sure how relevant that is,
since most people would be careful about not adding honey supers when
feeding, but here it is anyway...

Carbohydrate Composition of High-Fructose Corn Syrups (HFCS) Used for
Bee Feeding: Effect on Honey Composition

In this study, the carbohydrate 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. Fructosyl-fructoses and some
unknown carbohydrates, which could correspond to fructosyl-glucoses,
have been detected in HFCS for the first time, whereas SS were mainly
characterized by the high contents of sucrose. Hydroxymethylfurfural
(HMF) content of samples supplied by beekeepers was much more
variable; the mean level of HMF was 64.61 ppm (±16.92 ppm, 95% CI
ranging from 26.91 to 102.31 ppm). Syrups were used to feed caged
bees and the resulting honeys produced were analyzed in order to
determine their influence in carbohydrate composition. Fructosyl-
fructoses were mainly detected in honeys from bees fed with HFCS, but
not from those honeys coming from free-flying bees or bees fed with SS.
