Effect of light and duration of exposure in counteracting aflatoxin B1 in broken rice

Effect of exposure of aflatoxin (AF) for its reduction was studied under sunlight or UV light. The broken rice was artificially contaminated with aflatoxin B1 (209.99 +/- 4.39 ppb) and was exposed to either sunlight or UV light for different periods, viz. 0, 1, 2, 4, 8 and 16 h. The reduction in aflatoxin content in feedstuff was recorded with TLC method. It was revealed that both the type of exposure reduced the AF content and the reduction was proportion to the exposure period. After 16 h of exposure the per cent reduction in AF content was recorded to be 74.85 and 53.63 in sunlight and UV light, respectively. It could be concluded that the sunlight can be efficiently used in counteracting aflatoxin B1 in broken rice.
