چکیده مقاله:
Aflatoxins are secondary fungal metabolites with carcinogenic potential and physical deformities, particularly with the effect on suppressor gene P 53. From this group of toxins, aflatoxin B1, throughcontamination of animal feed to some species of Aspergillus, most notably, species are flavus andparasiticus, can be converted to aflatoxin M1 in milk. Elimination of aflatoxin contamination in the corn infested by Tymarazn and citric acid can reduce the contamination of animal feed and foodproducts. Decontamination in the corn contaminated with aflatoxin, by ozone treatment and citric acid,can reduce contamination of animal feed and food products. HPLC with immunoaffinity column was used in the measurement from aflatoxin, but ozone in 3 levels with 3 replications with citric acid (N1) has done, and we determine its optimum value, then the effect of citric acid - ozone was studied.Results showed that the fungi Aspergillus flavus and parasiticus aflatoxin in corn contaminated equals 73.124 ppm, and the amount of aflatoxin in a sample with citric acid ppm 57.83, the amount of aflatoxin in the sample by ozone disinfection with 80/07 PPM, and the amount of aflatoxin in the ozonedisinfection and citric acid equivalent to 71.77 ppm that in samples treated with citric acid and ozone disinfection and ozone disinfection with citric acid reduced aflatoxin 1M in milk, respectively, 33, 36, 38 percent REPORTS were followed.
