High-fructose corn syrup (HFCS) is a widely used liquid sweetener produced from corn starch by hydrolysis and partial isomerization of glucose to fructose. During these processing steps, sugars can be considerably degraded, leading, for example, to the formation of reactive α-dicarbonyl compounds
Glyoxal (GO) is one of the major toxic intermediates generated during lipid oxidation and degradation. We investigated the inhibitory activities and mechanisms of propyl, octyl, and dodecyl gallates (PG, OG, and DG) on the formation of GO in buffer and during thermo-processing of corn oil, and the
Sugar-sweetened carbonated soft drinks (CSDs) are broadly consumed worldwide. The added sugar, particularly high-fructose corn syrup (HFCS), can be an important source of sugar degradation products, such as α-dicarbonyl compounds. This study recorded the α-dicarbonyl profile in CSDs by
Dietary oils--tuna, salmon, cod liver, soybean, olive, and corn oils--were treated with accelerated storage conditions (60 degrees C for 3 and 7 d) and a cooking condition (200 degrees C for 1 h). Genotoxic malonaldehyde (MA), glyoxal, and methylglyoxal formed in the oils were analyzed by GC. Salmon
Three α-ketoaldehydes, potentially present in high fructose agave syrups (HFASs) as intermediates of the Maillard reaction, were determined. A previously reported HPLC-FLD procedure based on pre-column derivatisation with 4-methoxy-o-phenylenediamine was adopted, yielding the method quantification
