Acrylamide: Formation, Occurrence in Food Products, Detection Methods, and Legislation
(2014)This review aims at summarizing the most recent updates in the field of acrylamide (AA) formation (mechanism, conditions) and the determination of AA in a number of foods (fried or baked potatoes, chips, coffee, bread, ... -
Analytical methods of biological monitoring for exposure to pesticides: Recent update
(2007)Extensive use of synthetic pesticides for agricultural and nonagricultural purposes began in the past 50 years. As a result of their wide and extensive application, exposure to hazardous pesticides is a concern to the ... -
The application of an improved method for trans-resveratrol to determine the origin of Greek red wines
(2001)A rapid and sensitive method has been developed for the determination of trans-resveratrol in wine. This method consists of a solid phase extraction step followed by a rapid HPLC quantification step (30 min). The improvement ... -
Applications and Biomonitoring Issues of Recombinant Erythropoietins for Doping Control
(2011)The biochemical actions and side effects of recombinant erythropoietins (rhEPOs), their analogs and mimetics, their misuse as doping agents, and the principal analytical strategies developed to identify them in athletes' ... -
Assessment of polyphenolic content, antioxidant activity, protection against ROS-induced DNA damage and anticancer activity of Vitis vinifera stem extracts
(2013)Grape extracts and wine have been studied widely due to their beneficial effects on human health. However, there are only few studies from grape stems extracts. Therefore, the main objective of the present study was the ... -
Determination of diphenylamine in contaminated air of agricultural buildings using active sampling on solid sorbents
(2012)This paper reports the results of a study carried out with solid sorbents in order to establish the optimum procedure for sampling and determination of diphenylamine (DPA), the most widely used post-harvest chemical in ... -
Determination of xylazine and its metabolites by GC-MS in equine urine for doping analysis
(2004)Xylazine and its main metabolites were detected in equine urine after a single-dose intravenous administration of 0.98 and 1.01 mg/kg body weight xylazine, respectively, in two horses, in order to be used for equine doping ... -
Development and validation of an HPLC-DAD method for the simultaneous determination of most common rice pesticides in paddy water systems
(2012)Rice crop is mainly cultivated in large river basins which constitute unique ecosystems and their ecological quality is invaluable. However, the high loads of pesticides used in rice cultivation contribute to the contamination ... -
Development of GC-MS/MS method with programmable temperature vaporization large volume injection for monitoring of 17 beta-estradiol and 2-methoxyestradiol in plasma
(2012)Monitoring of estradiol and its metabolites in biological samples is essential for the accurate diagnosis of a number of endocrine diseases. In this study, a sensitive, precise and specific GC-MS/MS method for the ... -
Gas chromatographic - Mass spectrometric cardiotonic glycosides detection in equine urine doping analysis
(2004)A screening method for the detection of cardiotonic glycosides in horse's urine is presented in this paper. This method is based on the detection by gas chromatography-mass spectrometry (GC-MS) and gas chromatography-high ... -
Headspace single-drop microextraction of common pesticide contaminants in honey-method development and comparison with other extraction methods
(2012)In the present study the main factors that may influence the headspace single-drop microextraction (HS-SDME) of common pesticide contaminants (diazinon, lindane, chlorpyrifos ethyl, p,p'-DDE, and endosulfan) that may occur ... -
Implementation of hazard analysis critical control point (haccp) system to the non-alcoholic beverage industry
(2001)Non-alcoholic beverages, particularly, bottled water and fruit juices (carbonated and non-carbonated) are the most widespread food industries worldwide. The industry objective is to process at the lowest possible cost while ... -
Implementation of quality control methods (physico-chemical, microbiological and sensory) in conjunction with multivariate analysis towards fish authenticity
(2005)Nowadays authenticity of foods and fish in particular has become of crucial importance because of high number of adulteration cases. Authenticity control has gained ground thanks to the development of several rapid ... -
