method for removing propanedial (MDA) from oils includes the following steps: 30g of edible soybean salad oil (its MDA content was determined to be 1.50 μg·g⁻¹ using the TBA colorimetric method) is weighed into a 100ml round-bottom flask. 30mg of 98% concentrated phosphoric acid is added, and the mixture is stirred at 50 rpm for 30 min at 50°C. Then, 0.3g of sodium glutamate is added, and the mixture is stirred at 50 rpm for 60 min at 50°C. After the reaction, the soybean oil is centrifuged to recover 28.3g of soybean salad oil. The MDA content was determined to be 0.40 μg·g⁻¹ using the TBA colorimetric method, and the MDA removal rate was 73.3%. |

ChEBI: A dialdehyde that is propane substituted by two oxo groups at the terminal carbon atoms respectively. A biomarker of oxidative damage to lipids caused by smoking. It exists in vivo mainly in the enol form. | [Uses]
Propanedial, exists in horseradish hairy root taht has shown strong antioxidant capacity under arsenic stress which indicates possible use of Armoracia rusticana plants for phytoremediation. | [storage]
Unstable and easily polymerizes. The generation of MDA in situ from the hydrolysis of its bis-acetals results in the formation of a number of side products, including β- alkoxyacrolein, 3,3-dialkoxypropionaldehyde, and fluorescent condensation polymers of MDA. Crystalline sodium MDA, which is much more stable than MDA, is the recommended synthetic reagent. Sodium MDA, if stored under nitrogen in a refrigerator, is stable for months. |
