OAR@ICRISATComparison of different methods for extraction and estimation of aflatoxin B1 in groundnutV KMehanauthorT NBhavanishankarauthorJ SBediauthorAflatoxin extraction methods namely Best Food (BF), Contaminant Branch (CB), Pous’ and Romer’s and analytical methods namely thin-layer chromatography, spectrophotometric and minicolumn techniques, in different combinations, were compared for their efficiency for determining aflatoxin B1 occurring naturally in groundnuts and also for estimating aflatoxin B1 levels in groundnut meal samples spiked with known quantity of the toxin. The BF and Pons’ methods gave better efficiency than the other two methods. Spectrophotometric method was more effective than TLC and minicolumn techniques. BF method was found relatively less expensive and less time consuming as compared to other extraction methods. The Pons’ method was found convenient while handling large numbers of samples especially in the absence of centrifuge facilities required for the BF method.GroundnutEntomology1985Association Food Scintist and Technologist IndiaArticle
