| Abstract: |
| The aflatoxin B1 content and quality indexes of peanut oil pressed from peanut which was treated by alkaline solution were measured. The results indicated that the treatment of peanut with alkaline solution had a certain effect on removing aflatoxin B1 from peanut oil. Under the conditions of pH 13.40, alkaline solution dosage 10% and treatment time 15 min, the removal rate of aflatoxin B1 in peanut（grade four）oil was 93.3%. Under the conditions of pH 13.44, alkaline solution dosage 7.5% and treatment time 25 min, the removal rate of aflatoxin B1 in peanut（grade three）oil was 98.0%. Alkali solution treatment had certain influence on the acid value of peanut oil, which was within the standard range, and it had no definite influence on the peroxide value, iodine value and fatty acid composition. |
