| titleOfInvention | Propyl esterification analysis method of organic acids in tobacco and tobacco products |
| abstract | The invention provides a method for analyzing propyl esterification of organic acids in tobacco and tobacco products, comprising the following steps: 1) Adding sulfuric acid-n-propanol solution to tobacco and tobacco products for propyl ester derivatization and then vibrating extraction to obtain samples solution; 2) add the standard samples of various organic acids to dilute and constant volume with solvent respectively, and obtain the mixed standard solution; 3) carry out the gas chromatography-mass spectrometry measurement with the sample solution and the mixed standard solution respectively, compare retention time qualitatively, determine Various organic acids in the sample solution, and then calculate the content of various organic acids in the sample solution by the internal standard standard curve method. The propyl esterification analysis method of organic acids in tobacco and tobacco products provided by the present invention can simultaneously quantitatively detect volatile organic acids, non-volatile organic acids and higher fatty acids in tobacco and tobacco products, with high precision , good repeatability and excellent recovery rate. |
