Detoxification of groundnut seed and products in India
1989
Shantha, T.
The exposure of groundnut oil contaminated with aflatoxin B1 to bright sunlight for a given period of time completely destroyed the toxin. The safety and shelf life of the sunlight-exposed oil have been confirmed. Aflatoxin is present in finely suspended solids in the oil and most of it can be removed by filtration or by extraction with 10 per cent NaCl. Aflatoxin-contaminated groundnut kernels (0.5-mm thick flakes) can be partially detoxified if exposed to sunlight for 14 h. To remove aflatoxin from groundnut cake, 50 per cent alcohol, acetone, methanol, or 1 per cent calcium chloride can be used. Treating the protein isolate with hydrogen peroxide, and groundnuts in the form of thin flakes or groundnut cake powder with urea and soyabean flour, with or without formaldehyde can destroy 90 per cent of their aflatoxin content
