In this research, 47 wine samples produced from 2001 to 2002 harvest period in four Turkish regions were analyzed for the presence of ochratoxin A (OTA). Based on the results, the OTA levels of red wines are generally higher than those of white and rose wines.

Flour delivered to a school in the Bournemouth area was found by thinlayered chromatography to contain up to 6.25 mg/dg of ochratoxin. A. Penicillium cyclopium, a fungus known to produce this toxin, was found in discoloured portions of the caked flour. Ochratoxin was also found in a second sack delivered to the school, but not in samples of sound flour

Metabolic Pathways of Ochratoxin A
Current Drug Metabolism, 2011Ochratoxin A (OTA) as a carcinogenic of group 2B to humans is produced by various fungi strains as Aspergillus and Penicillium. It is one of the most common contaminant in foodstuff. OTA is nephrotoxic, hepatotoxic, teratogenic, and immunotoxic and is assumed to cause Balkan Endemic Nephropathy (BEN), a chronic kidney disease in humans when it is ...

Ochratoxin A from a toxicological perspective
Journal of Veterinary Pharmacology and Therapeutics, 2000Ochratoxin A (OTA) is a widespread mycotoxin which is produced mainly by the mould fungi Aspergillus ochraceus and Penicillum verrucosum during the storage of cereals, cereal products and other plant‐derived products such as herbs, spices, grapes, etc.

Ochratoxin A and Related Mycotoxins
2014Ochratoxins are toxins produced by fungal species belonging not only to Aspergilli but also to Penicillia with ochratoxin A (OTA) being the main toxin of the group followed by ochratoxin B (OTB) and ochratoxin C (OTC). These mycotoxins are formed in a variety of plant products as well as in some animal-derived products following fungal invasion.

A New and Expedient Total Synthesis of Ochratoxin A and d5-Ochratoxin A
Synthesis, 2009A new total synthesis of the mycotoxin ochratoxin A (OTA) is presented, in which it is prepared in 9% overall yield from commercially available substrates. The key step consists of the condensation reaction between protected L -phenylalanine and 5-chloro-8-hydroxy-3-methyl-1-oxoisochromane-7-carboxylic acid (ochratoxin α, OTα). The same strategy could

A broad-specific photoelectrochemical (PEC) immunosensor was developed for the simultaneous detection of ochratoxin A, ochratoxin B and ochratoxin C (OTA, OTB, OTC) by using the direct growth of CdS nanorods on FTO as the photoelectrode and Au nanoflowers-modified glass carbon electrode (GCE) as the bioelectrode.

Ochratoxin A and ochratoxin-producing fungi on cereal grain in China: a review
Food Additives & Contaminants: Part A, 2015The mycotoxin ochratoxin A (OTA) is known to be the main contaminant of cereal grain and has become increasingly important in recent years. Therefore, a survey of ochratoxigenic fungi and OTA contamination in China is a special challenge. This paper summarises data on cereals and moulds (Aspergillus niger, Penicillium verrucosum, Aspergillus ochraceus,

Recommendations. Studies should be conduced to clarify the mechanism by which ochratoxin A induces nephhrotoxicity and carcinogenicity. Appropriate sampling procedures should be developed for food commodities likely to be contaminated with ochratoxin A.

Mycotoxins are produced by fungi, commonly known as mold. Ochratoxins are a dangereous group of mycotoxins produced as secondary metabolites by several fungi of the Aspergillus or Penicillium families. Ochratoxin have been detected in foods and beverages, including grape juice and wine.
