Background: This cross sectional study was conducted to evaluate the effect of &gamma-rays and electron-beam irradiation with a commercial toxin binder-milbond-TX on the performance, feed components, and meat quality of Japanese quails challenged with aflatoxin B1. Methods: Overall, 168 One-d-old chicks (Japanese quails) were allocated to eight treatments with three replicates based on a com...

RNA synthesis (5, 8, 20), a secondary consequence of inhibition of RNA polymerase activity (6, 9, 10). The present experiments were undertaken to provide further information on several aspects of hepatocyte nuclear responses. Specifically, earlier studies have, for the most part, involved observations made at one or a few fixed time intervals following toxin treatment. Also, they have often bee...

background: aflatoxins cause health hazards to human and animals and has also economical problems. therefore, the de­toxification effect of citric acid was investigated in rice as the main food of iranian people. methods: initially 275 samples of rice were examined for aflatoxins by hplc. the aflatoxins contaminated samples were later treated by aqueous citric acid and detoxification of aflatox...

Evaluation of kinetic model aflatoxin B1 adsorption by Saccharomyces cerevisiae treated with acid and ultrasonic in Sangak bread dough

West African Aspergillus flavus S isolates differed from North American isolates. Both produced aflatoxin B1. However, 40 and 100% of West African isolates also produced aflatoxin G1 in NH4 medium and urea medium, respectively. No North American S strain isolate produced aflatoxin G1. This geographical and physiological divergence may influence aflatoxin management.

Thirty-three samples of wheat of the 1982 crop year from Kansas and Nebraska were analyzed for deoxynivalenol, T-2 toxin, zearalenone, and aflatoxin. Deoxynivalenol was identified in 31 of 33 samples, zearalenone was identified in 3 of 33 samples, and aflatoxin B1 was identified in 23 of 31 samples. One 1982 wheat sample from Illinois and one from Texas were also contaminated with deoxynivaleno...

BACKGROUND Aflatoxins are the most common mycotoxins that contaminate crops. They are produced by fungi such as Aspergillus flavus and Aspergillus parasiticus. Wheat (Tricitumaestivum) is one of the most important staple foods used in Iran, and the environmental conditions in the north of Iran are favorable to fungal growth. This study was designed in order to determine the aflatoxin concentrat...

A simple procedure was developed for in vitro synthesis and characterization of aflatoxin B1-lysine adduct using aflatoxin B1, N-alpha-acetyl lysine and m-chloroperbenzoic acid (MCPBA). At a molar ratio of 1:16 (aflatoxin B1:N-alpha-cetyl lysine), the recovery of adduct was 62%. Analysis of the adduct by thin-layer chromatography showed a single spot (Rf = 0). Absorption spectra of the adduct s...
