Embodiment 1
[0041] The analysis method for detecting 4 kinds of furan compounds and 1 kind of pyran compound in beer in this embodiment adopts the method of solid phase extraction (SPE) analysis method combined with gas chromatography / mass spectrometry (GC-MS) analysis method, including The following steps:
[0042] The first step, preparation: exhaust the finished beer for standby, select the solid phase extraction column, and then activate the solid phase extraction column. Selection and activation of solid-phase extraction column: select polystyrene / divinylbenzene small column, and pass through the column with 4mL n-hexane, 10mL water, 4mL ethanol, and 10mL water to activate before loading the sample.
[0043]The second step, solid-phase extraction (SPE): take 10mL of wine and pass it through the solid-phase extraction column, wash with 5mL of pure water, and then use 2mL of ethanol to elute the measured components adsorbed on the solid-phase extraction column, and then Take 1 mL of t...
