|Searching for Urinary Biomarkers of Exposure to Heterocyclic Amines (HCAs)|
Rosa Busquets, Henrik L. Frandsen, Kerstin Skog
Heterocyclic amines (HCAs) are foodborne carcinogens present in cooked meat and fish, mainly. Metabolites of HCAs have been determined in urine from volunteers following a controlled meal.
|Rapid Quantification of Proteins in Complex Matrices using the DeNovix DS11 Microvolume Spectrophotometer|
Mebs A Surve & Dan Schieffer
In this poster, we will introduce the DeNovix DS-11 as the next generation in microvolume spectrophotometry.
|Mixtures Analysis of Complex Mixtures|
Michael Bernstein; Carlos Cobas; Santi Domínguez; Manuel Pérez; Agustín Barba
We describe an NMR method to quantify mixture components in wine, edible oils, etc. The method is fully customizable, and amenable to high throughput operation.
|A Complete Wine Analysis Using Multiplets Detection|
Dr Michael Bernstein1; Agustín Barba1; Dr Susanne Klein2; Dr Andrea Dreiseitel2; Daniel Heidger2 and Volker Heidger2
NMR mixtures analysis can be used to determine the concentration of key components in wine. Here we show the analysis using SMA from Mestrelab.
|DPPH scavenging activities of selected flavonoids and their mixtures|
The aim is to identify the ati-oxidant activity of selected flavonoids (quercetin, luteolin and galangin) and their mixtures using DPPH method including their synergistic or antagonistic interactions.
|Effects of aquaculture effluents on nitrogen characteristics in two Chinese estuaries|
David Kaiser, Lucia S. Herbeck
The poster describes similarities and differences of the effects aquaculture effluents have on the nitrogen composition in estuarine waters of two sites in southern China
|Correlation between plasma levels of lutein and oxidized low density lipoproteins: a short human intervention study|
Tiziana Bacchetti, Gianna Ferretti
The increase of plasma carotenoids, in particular lutein, after dietary treatment for two weeks is associated with a significant protective effect against lipid peroxidation of plasma lipoproteins.
|Analysis of 10 systemic pesticide residues in various baby foods using liquid chromatography-tandem mass spectrometry|
Jae-Han Shim, Angel Yang, A. M. Abd El-Aty, Jong-Hyouk Park, Ayman Goudah, Md. Musfiqur Rahman, Jung-Ah Do
The method developed was sensitive and selective, and detected the analytes below the MRL established by the European Commission and the Korea Food and Drug Administration. The combination of QuEChERS sample preparation and LC-MS/MS analysis provided acceptable quantitative and qualitative results in baby food.
|Residue Analysis of Etoxazole in Red Pepper using Gas Chromatography: Application to Dissipation Pattern|
Sung-Woo Kim, Jin Jang, Md. Musfiqur Rahman, A. M. Abd El-Aty, Ah-Young Ko, Jong-Heui Choi, Jae-Han Shim
The dSPE of QuEChERS was replaced with an SPE cartridge, which provided a very clean chromatogram, although a small recovery percentage was obtained. The method fulfilled all validation criteria and was useful for monitoring etoxazole residues in red pepper. It can also be used and optimized for other fruit and vegetable matrices.
