Determination of moniliformin in maize by ion chromatography

Analytical and Bioanalytical Chemistry, 2002
An ion chromatographic method for the determination of the mycotoxin moniliformin in maize was developed. The method contains a fast and simple clean-up procedure, which allows high volume sample injection. No further pre-concentration step is required. The limit of quantification was estimated to be 0.12 mg/kg moniliformin in maize. In contrast to the

Moniliformin in barley inoculated withFusarium avenaceum

Food Additives and Contaminants, 2002
To assess production of the mycotoxin moniliformin, inoculation trials with four barley cultivars and local isolates of Fusarium avenaceum were performed at two different experimental farms in southern Manitoba, Canada, during 1997-99. In the 1997 study, moniliformin was detected in 11 of 16 barley rows at levels between 0.19 and 1.62 mg g(-1), and F ...

Moniliformin production byFusarium species isolated from Argentinian corn

Mycotoxin Research, 1996
Forty-one isolates ofFusarium obtained from the main Argentinian corn production area were tested for their ability to produce moniliformin. One of 22 isolates ofF. moniliforme, 2/10 of F.proliferatum and 3/9 ofF. subglutinans, produced moniliformin in a range between 0,3 to 2,7 mg/g.

[Detoxification of moniliformin].

Wei sheng wu xue bao = Acta microbiologica Sinica, 1994
Moniliformin is highly toxic to animals. It can be detoxified by treating with Ozone (O3). The structure of moniliformin treated with O3 was analysed by means of IR and NMR spectrum etc. It was proved that the double bond was disappeared and the 4-C ring structure was opened.

Enzyme-Assisted Extraction of Moniliformin from Extruded Corn Grits

Journal of Agricultural and Food Chemistry, 2005
Water has been known to be the ideal solvent for moniliformin but is not suitable to extract this toxin from cooked matrices due to instant swelling upon addition of the solvent. In this study, an improved method to extract moniliformin from extruded corn grits using alpha-amylase was developed.

Moniliformin and the European Corn Borer (Ostrinia nubilalis)

Mycotoxin Research, 1991
A representative survey was made of maize ears of the 1988 and 1989 crop in Austria to establish the influence of corn borer injuries onFusarium species involved in ear fusariosis andFusarium toxin production.TheFusarium species most frequently isolated from rot-damaged ears wereFsacchari var. subglutinans (about 50 %) andF.

Analysis of the Fusarium Mycotoxin Moniliformin in Cereal Samples Using ¹³C₂-Moniliformin and High-Resolution Mass Spectrometry

Journal of Agricultural and Food Chemistry, 2012
Moniliformin is a mycotoxin produced by fungi of the Fusarium genus and occurs as a contaminant of different cereals worldwide. This study describes the first application of isotopically labeled (13)C(2)-moniliformin for the analysis of moniliformin in cereals. Moniliformin is a small and ionic molecule that forms only a single sensitive fragment ion

Quantitative determination of moniliformin in vegetable foods and feeds

Fresenius' Zeitschrift für analytische Chemie, 1984
A suitable and simple method for the quantitative determination of moniliformin in vegetable foods and feeds is described. The mycotoxin was extracted by Soxhlet extraction with methanol from mouldy maize, rice, rye, oats, wheat and barley samples. Moniliformin was determined by thin-layer chromatography (TLC) using N-methylbenzthiazolon-2-hydrazone ...

Synthesen von Moniliformin, einem Mycotoxin mit Cyclobutendion‐Struktur

Helvetica Chimica Acta, 1978
Syntheses of Moniliformin, a Mycotoxine with a Cyclobutenedione StructureSix different routes to 3‐hydroxy‐3‐cyclobutene‐1, 2‐dione (4), the free acid of the mycotoxine Moniliformin (=alkali salt of 4) are described. A common feature of all pathways is the synthesis of cyclobutanes having the oxidation level 6.

Reduction of Moniliformin in Corn by Heat Processing

Journal of Food Science, 2003
ABSTRACT: The effects of autoclaving, baking, extrusion, frying, and roasting on the stability of moniliformin (MON) in spiked (5 μg/g of MON) corn‐based food products were investigated. Roasting corn meal at 218 °C for 15 min had the most significant effect (p ≤ 0.05) on the reduction of MON (44.6%).
