| Abstract | ||
| The aim of the study was to investigate the effect of citric acid and ammonium hydroxide on the detoxification of aflatoxines in rice . results indicated : 1-The using of citric acid with heating at 100 C° and shaking for one hour resulted in the detoxification of aflatoxins B1,B2,G1 and G2 in rice by the percentage 91.2,55.8, 100 and 55.6% respectively .While the using of citric acid with heating at 100 C° and incubation for one week at 20 C° resulted in the detoxification of the mentioned aflatoxins in rice by the percentage 100,32.9, 100, and 47.6% respectively. 2- The use of ammonium hydroxide with heating at 100 C° and shaking for one hour detoxificated the aflatoxins B1,B2,G1 and G2 in rice by the percentage 73.6,79.5,90 and 67.4% respectively. While the use of ammonium hydroxide with heating at 100 C° only ,then incubation the rice samples for one week at 20 C° resulted in the detoxification of the flatoxins mentioned above by the percentage 87.4,88.9,97.9 and 98.7% respectively. Statistical analysis did not show significant differences (at a=0.05) between the two chemical detoxification methods applied on rice samples. | ||
