Fifty individual figs which had been rejected as potentially contaminated by sorting under UV light were separately analysed to identify the presence of fungi and their mycotoxins. Aflatoxin B-1 was found in 49 samples with levels ranging from 0.7 to 222 ng g(-1), with 40 individual figs containing more than 2 ng g(-1), indicating the efficacy of the UV screening process in identifying contaminated fruit. Ochratoxin A (OTA) was found in 32 of the figs at levels from 0.4 to 1710 ng g(-1), with 50% of the samples containing levels above 1 ng g(-1). There was no evident correlation between levels of aflatoxin B-1 and levels of OTA. Twenty fungal species were isolated from the outer and inner surfaces of the figs, some of which were subsequently cultured on YES and PDB and the media analysed for the presence of aflatoxin B-1 and OTA to establish their toxigenicity.

Trace level determination of beryllium in natural and flavored mineral waters after pre-concentration using activated carbon KILINÇ, ERSİN; Bakirdere, Sezgin; YAMAN, MEHMET (Informa UK Limited, 2011-01-01) The concentrations of beryllium (Be) in natural and flavored mineral water samples were determined by flame atomic absorption spectrophotometer (FAAS) after pre-concentration based on the complexation of Be(+2) with a mixture of acetylacetone (pentane-2,4-dione) plus morin (3,5,7,2',4'-pentaoxyflavone) and adsorption on activated carbon. The adsorbed complex was eluted with 1.5 ml of 2.0 M HNO(3) and evaporated to dryness. After adding 1.5 ml of 2 M HNO(3) and centrifuging, Be in acid solution was determine...
A critical review of the specifications and performance of antibody and DNA-based methods for detection and quantification of allergens in foods Senyuva, Hamide Z.; Jones, Ivona Baricevic; Sykes, Mark; Baumgartner, Sabine (Informa UK Limited, 2019-01-01) Despite the availability of a large number of antibody and DNA based methods for detection and quantification of allergens in food there remain significant difficulties in selecting the optimum technique to employ. Published methods from research groups mostly contain sufficient detail concerning target antigen, calibration procedures and method performance to allow replication by others. However, routine allergen testing by the food industry relies upon commercialised test kits and frequently the suppliers...
Determination of minor and trace elements in Turkish diet by duplicate portion technique Parr, R. M.; Mumcu, Taşkın; Gökmen, İnci; Gökmen, Ayfle Filiz; Aras, Namık Kemal (Springer Science and Business Media LLC, 1988-10) The minor and trace element content of diet samples from two different social population groups were determined. Samples were prepared by duplicate portion technique by colecting everything 16 subjects ate and drank during a 3-day period. Samples were homogenized, freeze-dried and elemental concentrations of Br, Co, Cr, Cs, Fe, K, Na, Rb, Sc, Se and Zn were determined by instrumental neutron activation analysis. Elemental concentrations and daily dietary intake of the elements were compared with the diets o...
Analysis of cellulase and polyphenol oxidase production by southern pine beetle associated fungi Valiev, Abduvali; Ögel, Zümrüt Begüm; Klepzig, Kier D. (Springer Science and Business Media LLC, 2009-09-01) In this study, the production of extracellular enzymes by fungi associated with southern pine beetle was investigated for the first time. Cellulase and polyphenol oxidase production were analyzed for three beetle associated fungi. Only the mutualistic symbiont Entomocorticium sp. A was found to produce cellulases and polyphenol oxidase. In time course analyses of cellulase production in batch cultures, Entomocorticium sp. A showed maximum activity of 0.109 U/ml and 0.141 U/ml for total cellulase and endoglu...
Rapid LC and LC/MS for routine analysis of mycotoxins in foods Senyuva, H.; Gilbert, J.; Özcan Kabasakal, Süreyya; Gurel, N. (Wageningen Academic Publishers, 2008-08-01) Affinity column clean-up of food samples for mycotoxin analysis produces extracts which are free of co-extractives and therefore require little chromatography for separation and quantification of the target analytes. Using such clean extracts, we report rapid chromatographic methods for aflatoxins B(1), B(2), G(1) and G(2), aflatoxin M(1), ochratoxin A, zearalenone and fumonisins. Using short columns with small particle size packing, HPLC conditions have been developed reducing analysis time typically by 75...
