| Research Abstract |
Acrolein (ACR, CH_2=CH-CHO) is a toxic aldehyde generated from exhaust gas, smoke of cigarette or heated frying oil. In this research, we targeted to the ACR from heated frying oil and inhibitory effect of some antioxidative oils or antioxidants on generation of ACR.At first we prepared the closed trapping apparatus of ACR in vapor phase from the heating oil. The level of ACR was determined by a specific ELISA method after completely trapping the vapor to distilled water. It was proved that the high level of ACR was generated in the vapor phase from heating oil with air bubblins, whereas lower in oil phase. The ACR generation was inhibited by the roasted seed oils rather than the unroasted seed oils. From roasted sesame seed oil, it was identified sesaminol as one of the antioxidants. It was proposed that the sesaminol may be produced during roasting from some sesaminol glycosides. The banboom charcoal was a powerful inhibitory material of ACR generation from heated oil. On the other hand, modification of lipase by ACR caused the lowering of its activity.
