Aflatoxin B1 elimination in low-grade maize by co-influence of heat and chemical treatment

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 removed low-grade after sprinkling w/v at 50°C 24 h reduced aflatoxin B1 content to 4.25 µg/kg 60.35% reduction initial value. The use solution simple influenced fungal contamination B1.
