Aspergillus carbonarius can produce a possibly carcinogenic mycotoxin named ochratoxin A (OTA). The metabolism of this fungus also impact grape and wine quality as it influences the volatile phenolic profiles, which are related to aroma antioxidant activity, respectively. objective study was evaluate effect A. on OTA levels for first time profile activity grapes their respective wines. Cabernet Sauvignon (CS, red) presented higher susceptibility than Moscato Italico (MI, white) in musts were...
Compounds with toxic potential may occur in beer, such as carbonyl compounds (acetaldehyde, acrolein, ethyl carbamate [EC] and formaldehyde) furan derivatives [furfural furfuryl alcohol (FA)]. The objective of this study was, for the first time, to validate a method based on headspace-solid phase microextraction using PDMS-overcoated fibre gas chromatography mass spectrometric detection selected ion monitoring mode (HS-SPME-GC/MS-SIM) investigate target beers. Analytical curves showed proper...
Ethanol is the major matrix constituent of beer and has been reported as an important interfering volatile during headspace solid phase microextraction (HS-SPME) minor compounds due to its displacement effect. The addition a thin hydrophobic polydimethylsiloxane (PDMS) layer on commercial divinylbenzene/Carboxen/PDMS (DVB/Car/PDMS) fiber was evaluated, for first time, minimize effect caused by ethanol in quantitative determination profile five stages brewing. Analysis were performed through...
Carbonyl compounds and furan derivatives may form adducts with DNA cause oxidative stress to human cells, which establishes the carcinogenic potential of these compounds. The occurrence vary according processing characteristics beer. objective this study was, for first time, investigate free forms target carbonyl [acetaldehyde, acrolein, ethyl carbamate (EC) formaldehyde] [furfural furfuryl alcohol (FA)] during brewing stages ale lager craft beers. Samples were evaluated using...
ABSTRACT: The goals of this study were to verify the occurrence furfuryl alcohol (FA) and carbonyl compounds (acetaldehyde, acrolein, ethyl carbamate (EC), formaldehyde furfural) in sparkling wines evaluate, for first time, whether consumption samples under could represent risk consumers health. These are electrophilic; therefore, may covalently bind DNA, which result mutagenicity. EC present at low levels (<1μg L-1) all samples. Acetaldehyde, furfural acrolein also found (<1.5, 1.4...
Mouthwashes are the most common antiseptic used for buccal hygiene. However, some studies have shown that these compounds containing alcohol can induce genotoxic and carcinogenic effects. The human micronucleus cytome assay (BMCyt) has been widely to investigate biomarkers DNA damage, cell death, cytockinesis defects basal frequency in cells. Thus, aim of this study was assess whether mouthwashes could genetic damage exfoliated cells epithelium by BMCyt. Sixty individuals participated study,...
