Besides this, for most samples analyzed the concentrations observed for HMF were also much higher than those reported in the literature by other researchers (1.3–1410 mg kg1) Cane syrups were characterized by lower amounts of HMF (109.2–893.1 mg kg1) (Table 3) and so as observed above for corn syrup, the concentrations of this contaminant found in Brazilian samples were higher than that reported in literature (100–300 mg kg1) Differences in HMF concentrations of cane and corn syrups can be explained considering several factors that promote the formation this contaminant in foods (thermal processing involving high temperatures, long storage
times and food chemical composition)
