Identification and mapping of new sources of resistance to aflatoxin accumulation in maize
Maize (Zea mays L.) susceptibility to ear rot and aflatoxin accumulation by Aspergillus flavus (Link:Fr) has caused significant economic losses for farmers in the U.S. over the past 30 years. Aflatoxin outbreaks are generally associated with high temperatures and low moisture levels common to the southern U.S. To identify aflatoxin accumulation resistance quantitative trait loci (QTL) and linked ...

Evaluation of maize inbred lines for resistance to aspergillus and fusarium ear rot and mycotoxin accumulation
Mycotoxin contamination in corn (Zea mays L.) grain is a worldwide threat to safety of both human food and animal feed. A select group of inbred corn lines was evaluated in field trials for ear rot caused by Aspergillus flavus and Fusarium verticillioides and mycotoxin accumulation in grain. Our goal was to identify lines resistant to both fungi. In separate tests, 20 inbred lines were inoculated ...

Zeolite and Mycotoxins: Aflatoxin Detoxication of Animal Feed by KMI Zeolite
General statement: Zeolites are crystalline, hydrated aluminosilicates of alkali and alkaline earth cations which possess three-dimensional crystal structures. They have the ability to lose and gain water reversibly, to adsorb molecules of appropriate cross-sectional diameter and to exchange their constituent cations (NH4+, Na+, K+, Ca2+ ). In a structural standpoint, clinoptilolite like zeolite ...

AFLATOXINS Toxins in Peanuts, Vegetable Matter and Milk
Aflatoxins occur naturally in peanuts, peanut meal, cottonseed meal, corn, dried chili pepper, etc. However the growth of mold does not always indicate the presence of toxin since the yield of Aflatoxins is dependent on growth conditions such as moisture, temperature, and aeration. The Aflatoxins are characterized as B for blue fluorescence and G for green fluorescence. The numerical subscripts ...

Analysis of Aflatoxin B1, B2, G1, and G2 in Corn Meal, Wheat Meal, and Raw Peanut Paste Matrices
The Supel Tox AflaZea SPE cartridge was used to demonstrate the cleanup of corn meal, wheat meal, and raw peanut paste matrices prior to the analysis of Aflatoxin B1, B2, G1, and G2. In the procedure, corn meal, wheat meal, and raw peanut paste extracts were spiked with Aflatoxin Standard Mix (Product No. 34036) and run through the Supel Tox AflaZea SPE cartridges. The eluate was collected and ...

Studies on the efficacy of physical, chemical and biological aflatoxin B1 detoxification approaches in red chilli powder
Aflatoxin free powdered red pepper (100 g) was spiked with 100 ppb of aflatoxin B1 (AFB1) in methanol and was subjected to various physical (UV irradiation, heating, microwave); chemical (oxidation, bleaching, ammoniation, sulphitation) and biological (enzymatic) treatments. The residual AFB1 was quantified by standard methods to find the efficiency of different treatments in degrading AFB1. ...

Multi-residue mycotoxin analysis single run analysis of deoxynivalenol, aflatoxins, ochratoxin a, zearalenone and fumonisin by HPLC and post-column derivatization
Although Aspergillus (Aflatoxins, Ochratoxin A) are generally associated with peanuts and Fusarium (Deoxynivalenol , Zearalenone) with wheat, these fungi and those that produce other toxins are not host selective and so can cross plant species. This situation is complicated by the fact that the microscopic mold may not be visible to the naked eye. Also, when infected grains are processed, any ...

Reduction of aflatoxin B1 and Ochratoxin A in cocoa beans infected with Aspergillus via Ergosterol Value
Aflatoxigenic and ochratoxigenic isolates were used to contaminate cocoa beans in this study and Ergosteol Values (EV) were assessed by means of visual inspection, Reverse Phase-High Performance Liquid Chromatography (RP-HPLC) and Gas Chromatography?Mass Spectrometer (GC?MS), respectively. Different concentrations of Aframomum danielli essential oils at 500, 1,000, 1,500, and 2,000 ppm were used ...

Feed to food risk assessment, with particular reference to mycotoxins in bovine feed
Recent food safety scares, in particular those relating to bovine spongiform encephalopathy and Escherichia coli, have highlighted the need to assure consumers of the quality of the food they eat. It is necessary to highlight the procedures in place for minimising potential risks to animals and subsequent risks to consumers from animal derived food products. The potential dangers of mycotoxins in ...

Multi-residue mycotoxin analysis of dry distillers grains
Distillers grains (DG) are the still residues after the ethanol has been collected. Approximately 90% of US production is used in domestic animal feed. Any Mycotoxins present in the fresh corn can be concentrated by a factor of three. Contamination can also occur during storage. This raises concern about the potential animal and human health hazards from the use of Mycotoxincontaminated ...

Vegetable Oil Processing Industry - Pollution Prevention Guidelines
Introduction Pollution Prevention Guidelines to provide technical advice and guidance to staff and consultants involved in pollution-related projects. The guidelines represent state-of-the-art thinking on how to reduce pollution emissions from the production process. In many cases, the guidelines provide numerical targets for reducing pollution, as well as maximum emissions ...
