Abstract
A practical, short cut, sensitive method for more rapidly determining aflatoxin in peanuts and peanut products has been developed. This was in response to the need to reduce the time required for analyses of peanut products in process. Through reductions in solvent volumes, utilization of pressure filtration for clarification, and substitution of liquid:liquid extraction for a lengthy column clean up, equivalent results are possible in less than one half the time required for the current official procedures. Sensitivity, precision and accuracy are comparable to the current methods for raw nuts and peanut butter. It is now possible to analyze a given ground sample of peanuts within a period of less than 90 min and one analyst can assay more than 16 samples within an 8 hr working day.
