ABSTRACT
The radio frequency (RF) heat treatment had effect to the enzymes activities. On treating temperature over 80 q
C for 10
minutes, the low activation of lipase was occurred. The better oil quality which has low level of hydrogen peroxide, peroxide
value and TBA value were achieved. RF heating treatments resulted in significantly lower number of A. flavus and aflatoxin B1
and the energy consumed than control treatment. Therefore, the RF stabilizing technique provided the high oil quality, less lipid
peroxidation and lower energy consumed than convectional drying
