| Abstract: |
| The analysis methods for triacylglycerols (TAGs) and its oxidized polymers (TGP) in edible oil were reviewed，containing gas chromatography，high performance liquid chromatography and supercritical fluid chromatography for analysis of TAGs，as well as size-exclusion chromatography，near infrared spectrometry，viscosity，dielectric constant and nuclear magnetic resonance for analysis of TGP. Analysis methods for TAGs had already made breakthrough. However，TGP was still studied as a monomer at home and abroad，and its chemical structure and formation mechanism had not been reported yet，so it need further research on the separation and structure identification. The study had important significance for quality supervision and safety ensurance of the edible oil. |
