| titleOfInvention | A kind of method for detecting mineral oil in chili oil by gas chromatography |
| abstract | The invention relates to the technical field of food detection, and specifically discloses a method for detecting mineral oil in chili oil by gas chromatography. The method includes the following steps: taking a mixed standard solution of C 7 to C 40 n-alkanes, diluting to a constant volume with n-hexane and performing isogradient dilution to obtain a series of standard working solutions, performing detection, recording chromatographic data and drawing a standard curve; using Ultrasound-assisted extraction of mineral oil in chili oil, the extract is subjected to centrifugation, concentration, and SPE column purification to obtain the sample to be tested; gas chromatography is performed to detect, record the chromatographic data, and compare with the standard spectrum and standard curve to obtain the sample to be tested. Type and content of mineral oil. The gas chromatogram obtained by the method provided by the invention has complete and clear peaks, high separation degree, and high sensitivity and accuracy. |
