Abstract EN

The aim of this study was to investigate the treatments of aflatoxins B1 and G1 which contaminated the corn by dual purpose oven oven (microwaves or ordinary and mixing) as follows: 100:0 , 80:20 , 60:40 , 40:60 , 20:80 and 0:100 for 3 , 5 and 10 minutes.

The percentage of aflatoxins destruction and the effect of aflatoxin destruction treatments on corn oil constants such as effect on free fatty acids percent, acid number and peroxide value.

Data show that treatment of the corn by dual purpose oven resulted reduction of aflatoxin B1 and G1 by about 25.4-100 and 32-100% respectively.

The reduction percent was increased with increasing the percentage of used microwaves energy and exposure period.

The percent of free fatty acids and acid value were significantly (P<0.05) changed according to nature of the treatment and microwave energy percent used.

Both parameters were significantly decreased in microwave treatment by 100 , 80 and 60%.

Whereas, peroxide number was generally found high (especially in control treatment) and then significantly decreased with increasing exposure period in dual purpose oven.
