تأثير اِستعمال الفرن ثنائي الغرض في تحطيم سموم ألافلا و الخواص الكيميائية للذرة الصفراء

الملخص EN

The aim of this study was to study the effect of destruction treatments of aflatoxins contaminated corn by dual purpose oven (microwave and heating).

Aflatoxins B1and G1 destruction on chemical constitutes treatments were as follows: 100:0, 80:20, 60:40, 40:60, 20:80 and 0:100 for 3, 5 and 10 minutes.

The percentage of the two aflatoxins destruction and the effect of aflatoxin destruction treatments on chemical properties of corn were calculated.

These were included moisture, protein, fat, ash, and carbohydrates %.

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

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

There was a significant (p<0.05) change in the chemical components of the corn in oven treatment.

Moisture percent decreased and this was resulted in increasing in protein, fat, ash and carbohydrates percent.

Changes in the components percent were different according to the percent of the microwaves energy and ordinary used and exposure period.
