Scope
Main technical content: Using adipic acid as an internal standard substance, a 10% (by volume) sulfuric acid-methanol solution is used to perform a methyl esterification reaction on free fatty acids in tea leaves at room temperature (around 25°C). The methyl esterified products are extracted with dichloromethane, and the free fatty acid content in the extract is determined using a gas chromatograph-mass spectrometer detector.
