This research investigated the optimal conditions of heat and chemical treatment for elimination aflatoxin. NaOH showed highest inhibition percentage (75.44%) Aspergillus flavus growth that was isolated from lowgrade maize. Low-grade maize contaminated with A. treated by varying three factors in levels: concentration (0, 2.5 5% w/v), temperature (25, 50 75°C) time (24, 48 72 h). Aflatoxin remov...
Residents of Qidong, People's Republic of China, are at high risk for development of hepatocellular carcinoma, in part from consumption of foods contaminated with aflatoxins.
