Aflatoxin B1, B2, G1, G2 (HPLC-FLD)

Aflatoxins are natural toxins produced by mould fungi and associated with liver cancer risk. In exports of nuts, dried fruit, cereals and spices the aflatoxin limit is set very tightly by country and product and is one of the most common reasons for rejected consignments.

Sample preparation begins with grinding and homogenisation so as to represent the lot; extraction, immunoaffinity column clean-up and HPLC fluorescence detection follow. B1, B2, G1, G2 and total aflatoxin are reported separately.
