ABSTRACT
OBJECTIVE:
To establish a method for the determination of three furfural compounds in coffee and its products by gas chromatography-tandem mass spectrometry.METHODS:
The samples were extracted with ethanol water(1â¶2, Vâ¶V) solution, ultrasonic with 10% Na_2CO_3 solution for 5 min, purified with 100 mg C_(18), 50 mg Srong Cation exchang(SCX), 150 mg anhydrous MgSO_4, separated by HP-INNOWAX capillary column(30 m×0.25 mm, 0.25 µm), detected by gas chromatography-tandem mass spectrometry, and quantified by isotope internal standard method.RESULTS:
The correlation coefficients(r) of the three furfural compounds were all greater than 0.999, the limits of detection were 0.004-0.011 mg/kg, and the limits of quantitation were 0.013-0.031 mg/kg. The average recoveries were 86.0%-112% and the relative standard deviations were 4.1%-10.6%(n=6), at 3 supplemental levels in 3 different coffee substrates. Nine samples of coffee beans, instant coffee and coffee drinks were tested, and all three components to be tested were detected.CONCLUSION:
The method is simple, rapid, sensitive, with good accuracy and precision. It is suitable for the determination of three furfural compounds in coffee and its products.Palavras-chave
