Studies on aflatoxin in rice: description and evaluation of a new apparatus for the separation of husk from dehulled rice contaminated with aflatoxin

Studies on aflatoxin in rice: description and evaluation of a new apparatus for the separation of husk from dehulled rice contaminated with aflatoxin

Journal of the Science of Food and Agriculture 46(3): 311-318

A simple apparatus and method developed for the separation of husk from dehulled (brown) rice contaminated with aflatoxin is described. The performance and efficiency of the apparatus was evaluated by passing a series of dehulled rice and husk mixtures through it. Subsequently the aflatoxin distribution in both rice and husk was determined. The range was 24 to 81% for aflatoxin B1 and 11 to 76% for B2, depending on the rice grain category and variety. The study indicates that the apparatus can be used conveniently to separate husk from aflatoxin-contaminated rice with a minimum hazard to personnel. It is therefore recommended for use particularly in developing countries, where laboratory test mills may not be available.
