| Abstract: |
| Glycidyl esters (GEs) and 3-monochloropropane fatty acid esters (3-MCPDE)are one of the main pollutants in the refining process of vegetable oil.GEs and 3-MCPDE are taken into human body with edible oil, hydrolyzed by human lipase,and the products glycidyl and 3-chloropropanol have nephrotoxicity and genotoxicity. GEs and 3-MCPDE in vegetable oil are mainly produced in the deodorization process of oil refining. Deodorization temperature and time have a great impact on the production of GEs and 3-MCPDE. The formation and removal of GEs and 3-MCPDE in the process of oil refining were reviewed, and it was pointed out that the decolorization and deodorization section promoted the formation of GEs and 3-MCPDE. The content of GEs and 3-MCPDE in vegetable oil could be reduced by inhibiting and removing their precursors, optimizing the deodorization conditions of vegetable oil, and removing GEs and 3-MCPDE from refined oil. Enzymes have the advantages of safety and non-pollution, and enzymatic transesterification is used to reduce diglyceride and monoglyceride in oil to be deodorized, thus reducing the formation of GEs and 3-MCPDE in the deodorization process will be the development trend to reduce GEs and 3-MCPDE. |
