Abstract:
      γ-oryzanol is an important nutrient, and the content of γ-oryzanol in rice bran oil is 1% -2%, which is a natural antioxidant. Since the composition of γ-oryzanol is complex,its ingredients have not been detected one by one. The current common analysis and detection techniques of γ-oryzanol in rice bran oil at home and abroad were compared.UV spectrophotometer was used for the rough determination of γ-oryzanol content, high performance liquid chromatography as an advanced means had accurate determination results, and LC-MS and GC-MS could accurately separate and detect the composition of ferulic acids,which contributed to the further study of physiological activities of γ-oryzanol.
