“…It also suggests that the molecule structure in post-treated aflatoxin contaminated samples changes, the lactone ring may be opened. Thus, detoxification initially involves the formation of the b-keto acid structure (catalyzed by de acidic medium), followed by hydrolysis of the lactone ring yielding the AFD 1 molecule, derivated from decarboxylation of the lactone ring-opened form of AFB 1 (Méndez-Albores et al 2005), which is 130 times less mutagenic in the Ames test and presenting 20-fold toxicity decrease (Schroeder et al 1985). Therefore, the fluorescence strength varies in the HPLC chromatograms at the same retention time values.…”

“…Considering that the acidic treatment protects ducklings from chronic aflatoxin toxicity and greatly reduces the mutagenic and carcinogenic activity of aflatoxins in the Ames test (Méndez-Albores et al 2005), the purpose of the present study was to determine the effect of dietary CA on the stability of B-aflatoxins in feed, as well as on growth performance and biochemical parameters in the blood of young broiler chickens.…”

“…It is one of the least susceptible foods to mycotoxins contamination while it can affected during the pre-or post harvest stage (1). Aflatoxins (AFT s) are the secondary metabolites mainly produced by Aspergillus flavus (2,3). This toxic substance, with four out of 20 different types which are known; including B1, B2, G1, and G2 could lead to some health problems (4).…”

Background: Rice is common foodstuffs in Iran. Aflatoxin contamination of rice can be hazardous human health and causes economic problems. Objectives: Determination of Aflatoxin levels was investigated on the imported rice which is consumed as the main food in this area. Materials and Methods: Two hundred samples of imported rice consisting; yellow (100) and white (100) rice were selected randomly. These samples were assessed for Aspergillus infection and the Aflatoxins B, G was detected by high performance liquid chromatography (HPLC) method. Results:The results showed, 33% and 47% of yellow and white rice samples had contaminated 0.34 and 0.58 part per billion (ppb) with Aflatoxin B1 respectively. It was observed 13% and 21% following samples had also contaminated 0.06 and 0.08 ppb Aflatoxin B2 respectively. The levels of G1 and G2 Aflatoxins were impossible to identify in these samples. Conclusions: According to proposed standards, none of the imported rice sample had not contaminated more than the maximum allowable concentrations of Aflatoxin.

“…Water content was determined by measuring the change of weight of approximately 2 g substrates after 24 h drying at 105 °C (modified from Mendez-Albores et al, 2005). Water content loss was calculated from the total weight of remaining substrate and water content per gram of dry substrate (Smits et al, 1996b).…”

Aims:The growth and metabolic activity of Aspergillus oryzae KKB4 in AFB1-contaminated corn and later coincided with AFB1 reduction and detoxification were investigated. Methodology and results:The decreasing of AFB1 amount by A. oryzae KKB4 could be clearly observed if the initial AFB1 concentration in corn was increased. Thus, moist-heated corn was artificially inoculated with Aspergillus flavus FNCC 62C7 to increase AFB1 content. AFB1-contaminated corn was applied as solid substrate and then inoculated with A. oryzae KKB4. During fermentation periods, the growth, metabolic activity, and AFB1 decline were investigated by glucosamine content, water content loss, and AFB1 concentration, respectively. The maximum growth was occurred in 4 th day at 1.499 ± 0.028 g glucosamine/ 100 g dry matter. The metabolic activity was going on up to the end of fermentation days, as shown as water content loss at 0.175 ± 0.007 g/g dry matter. In accordance with the growth and metabolic activity, the amount of AFB1 reduction was 37.04 ng AFB1/g dry matter during 5 days fermentation. According to toxicity analysis, it was found that the residues of AFB1 were not toxic to Bacillus megaterium cells. Conclusion, significance and impact of study: A. oryzae KKB4 is able to be applied in solid substrates as AFB1 reduction and detoxification agent. These lucrative effects are also important in relation with food and feed safety.
