Application of a fast high-performance liquid chromatography method for simultaneous determination of furanic compounds and glucosylisomaltol in breakfast cereals.

The high-performance liquid chormatography method reported in the present paper provides a fast, low-cost, precise, and simple technique to analyze simultaneously 3 different indicators of nonenzymatic browning, i.e., hydroxymethylfurfural (HMF), furfural, and glucosylisomaltol (GIM), in breakfast cereals. These compounds were extracted in aqueous solution and separated on a reversed-phase C18 column with water-acetonitrile (95 + 5, v/v) mobile phase under isocratic conditions. Average recovery rates for HMF, furfural, and GIM were 99.1, 98.4, and 99.4%, respectively. The coefficients of variation were 3.67, 2.42, and 1.59% for HMF, furfural, and GIM, respectively. The detection limit was 0.01 mg/kg, and the quantitation limit was 0.05 mg/kg for the 3 studied compounds.
