• Reference material
• Peanut oil
• Aflatoxins
• Quality assurance

The first peanut oil reference materials in naturally contaminated aflatoxins was developed, because of the high consumption of this product and the potential risk associated herewith. Based on liquid chromatographic method, homogeneity, short-term of 60 degrees C for seven days and long-term of 25 degrees C for twelve months' stability studies of candidates were assessed. The obtained data and statistical results showed a successful feasibility study, without any significant trend. Nine selected expert laboratories were invited to certify the contents of candidates using distinguish quantitative liquid chromatographic method. The certified values and expanded uncertainties (k = 2) for these two batches were 6.5 +/- 1.6 mu g/kg, 29.3 +/- 5.3 mu g/kg for aflatoxin B-1; 1.2 +/- 0.3 mu g/kg, 5.2 +/- 0.9 mu g/kg for aflatoxin B-2; 5.0 +/- 0.4 mu g/kg, 8.4 +/- 0.7 mu g/kg for aflatoxin G(1); and 2.1 +/- 0.2 mu g/kg, 3.5 +/- 0.2 mu g/kg for aflatoxin G(2), respectively.
