Reduction of aflatoxin B1 contamination in Pakistani wheat varieties by physical methods

In the study of effect of physical treatments,such as washing and heating,on the afb1 contaminated wheat varieties,it was observed that the reduction of afb1 was directly proportional to washing time in all the varieties. the concentration of afb1 was reduced more by heating than washing. the level of afb1in dried wheat decreased to more than 50% and 90% by heating in oven at 150 and 200 °c,respectively. however,the reduction of afb1 in wet wheat in which water (10%) was intentionally added was higher on heating at 100 °c for 30 min than that in the dried wheat.
