Emerging electrochemical sensing and biosensing approaches for detection of Fumonisins in food samples

Critical reviews in food science and nutrition, 2021
Fumonisins (FBs) can be found extensively in feedstuffs, foodstuffs, and crops. The consumption of the fumonisin-contaminated corn can result in esophageal cancer.

Molecular toxicology and carcinogenesis of fumonisins: a review.

Journal of environmental science and health. Part C, Toxicology and carcinogenesis, 2021
Fumonisins, discovered in 1988 are a group of naturally occurring toxins produced by fusarium pathogenic fungi. Besides their presence in animal feeds, contamination of human foods such as corn, millet, oats, rye, barley, wheat and their products are ...

Identification and Characterization of an Aspergillus niger Amine Oxidase that Detoxifies Intact Fumonisins.

Journal of Agricultural and Food Chemistry, 2020
Fumonisin contamination of maize damaged by Fusarium verticillioides and related species is a major problem when it is grown under warm and dry conditions. Consumption of fumonisin contaminated food and feed is harmful to both humans and livestock. Novel

Difficulties in fumonisin determination: the issue of hidden fumonisins

Analytical and Bioanalytical Chemistry, 2009
In this paper, the results obtained by five independent methods for the quantification of fumonisins B(1), B(2), and B(3) in raw maize are reported. Five naturally contaminated maize samples and a reference material were analyzed in three different laboratories.

Determination of fumonisins in milk

Journal of Environmental Science and Health, Part B, 1994
Fumonisin B1 (FB1) and fumonisin B2 (FB2) were determined in milk by liquid chromatography (LC) following immunoaffinity column cleanup. Recoveries from milk spiked with 5-50 ng each fumonisin/ml averaged 79-109%. The aminopentol hydrolysis product of FB1 (AP1) was determined by LC after cleanup on a C18 solid phase phase extraction column; mean ...

Fumonisins

International Journal of Food Microbiology, 1993
Fusarium moniliforme Sheldon is a common fungal contaminant of corn and produces a variety of mycotoxins. Among these are the recently discovered fumonisins, which are now known to cause certain animal diseases, namely leukoencephalomalacia in horses and pulmonary edema in swine.

Analysis of heat-processed corn foods for fumonisins and bound fumonisins

Food Additives and Contaminants, 2004
Thirty retail samples of heat-processed corn foods, i.e. corn flakes, corn-based breakfast cereals, tortilla chips and corn chips, were analysed for fumonisins--fumonisin B1 (FB1), fumonisin B2 (FB2) and hydrolysed FB1 (HFB1)--as well as for protein- and total-bound FB1. Bound (hidden) fumonisins cannot be detected by conventional analysis.

Free and hidden fumonisins in raw maize and maize-based products from China

Food Additives & Contaminants, Part B, 2019
The occurrence of free and hidden fumonisins in raw maize and maize-based products from China was investigated. A total of 58 samples were analyzed using high-performance liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS). Among all the

Fumonisins

2017
Fumonisins are fungal toxins found in maize and maize-based foods. Fumonisins are toxic to animals but their impact on human health is uncertain. Epidemiological evidence suggests that fumonisins are potential risk factors for neural tube defects (NTDs) and for growth retardation of young children living in areas where large amounts of fumonisin ...

Fumonisins and fumonisin analogs as inhibitors of ceramide synthase and inducers of apoptosis

Biochimica et Biophysica Acta (BBA) - Molecular and Cell Biology of Lipids, 2002
Sphingoid bases are growth inhibitory and pro-apoptotic for many types of cells when added to cells exogenously, and can be elevated to toxic amounts endogenously when cells are exposed to inhibitors of ceramide synthase. An important category of naturally occurring inhibitors are the fumonisins, which inhibit ceramide synthase through structural ...
