Method for detecting content of acetaldehyde and furfural in grape wine

The invention relates to food safety detection, and discloses a method for detecting a content of acetaldehyde and furfural in grape wine in order to solve the problems of complex and tedious pretreatment and high detection cost. The method comprises the following steps: distilling a grape wine sample; adding an internal standard solution; using a gas chromatography-flame ionization detector (GC-FID) to carry out analysis and detection; and quantitatively calculating the content of acetaldehyde and furfural in the grape wine by an internal standard method. According to the method, saccharide and pigment interfering substances in the grape wine are removed through a distillation method, acetaldehyde and furfural in the grape wine are accurately detected and analyzed by using a gas chromatograph, the pretreatment of the test method does not need derivatization, the method is rapid and simple, and the detection result is reliable and stable. The method provides a new detection method for detection of acetaldehyd
