Abstract
The effects of different inactivating treatments including hot air roasting normalpressure steaming highpressure steaming infrared roasting and microwave heating on the storage properties and flavor quality of oats were studied These methods significantly inactivated the lipase of oats even if using infrared roasting treatment had a worse inhibition effect of hydrolysis As a result the storage properties of oats were improved with different inactivating treatments except infrared roasting PCA analysis showed that all the oat flours could be clearly discriminated by the electronic nose Sensory evaluation showed that the qualities of oat flour were hot air roasting 725 infrared toasting 717 microwave heating 592 highpressure steaming 585 and normalpressure steaming 557 It was concluded that there was a significant relationship between inactivation treatment and oat flavor That is to say dry heating resulted in more favorable sensory quality of oat flour
