Arabinoxylans (AXs) are dietary fibers in monocotyledon cell walls that benefit digestive health and enhance food functionality. Despite their importance, no standardized method exists for AX quantification gluten-free (GF) cereals. This study investigated the effect of hydrolysis parameters GF cereals (maize, rice, oat) with varying content nutritional profiles to address matrix effects. The effects trifluoroacetic acid (TFA) concentration (0.25-4 M), temperature (90-127 °C), time (1-5 h)...
Abstract The present paper describes the development of a new clean‐up strategy for analysis aflatoxins (AFs) in food. sample preparation method is based on immuno‐ultrafiltration (IUF) which, contrast to immunoaffinity chromatography, makes use antibodies free form. After selecting an appropriate ultrafiltration (UF) device and optimizing different operation conditions IUF was applied maize rice. Quantification AFs carried out by HPLC fluorescence detection, after postcolumn derivatization...
The duplicate method for estimating uncertainty from measurement including sampling is presented in the Eurachem/CITAC guide. applicability of this as a tool verifying plans mycotoxins was assessed three case studies with aflatoxin B1 animal feedingstuffs. Aspects considered included strategies obtaining samples contaminated lots, assumptions about distributions, approaches statistical analysis, log10-transformation test data and estimates. results showed that when aggregate are formed by...
Abstract Background Recent studies indicate that amylase-trypsin inhibitors (ATIs) and certain carbohydrates referred to as FODMAPs (fermentable oligo-, di-, monosaccharides polyols) play an important role in promoting wheat sensitivity. Hitherto, no study has investigated the accumulation of ATIs during development caryopsis. We collected caryopses common cv. ‘Arnold’ at eight different grain developmental stages compositional changes ATI FODMAP content. Results The harvested were analysed...
Automatic and manual sampling for ochratoxin A (OTA) in barley grain was compared under industrial conditions considering uncertainty as well practical technical aspects. Ten tonnes of inoculated with Penicillium verrucosum were incubated until the OTA concentration reached approximately 15 µg kg(-1) sampled automatic sampling. nested experimental design ANOVA used to estimate variance components from sampling, sample reduction, preparation analysis. Manual resulted a high concentrations...
Abstract BACKGROUND Mycotoxin surveys play an essential role in our food safety system. The obtained occurrence data form the basis for assessment of exposure humans and animals to these toxic fungal secondary metabolites. Liquid chromatography coupled with tandem mass spectrometry (LC‐MS/MS) has become gold standard mycotoxin determination because it enables selective sensitive multi‐toxin analysis. Simultaneous several hundreds metabolites is feasible using this technique. In study, we...
The prohibition of processed animal proteins (PAPs) has been relaxed gradually since 2007. official control method for PAPs in feedingstuff, a combination light microscopy (LM) followed by PCR, is no longer sufficient. Thus, targeted LC–MS/MS was developed, which enables tissue-specific distinction between egg and dairy products, gelatine, derived from blood or muscle tissue the species ruminants, pigs, poultry, fish. Tissue-specific were analyzed after tryptic digestion to peptides with...
Assessing the quality of wheat, one humanity's most important crops, in a straightforward manner, is essential. In this study, analysis variance (ANOVA) simultaneous component (ASCA) paired with near-infrared spectroscopy (NIRS) was used as an easy-to-implement and environmentally friendly tool for purpose. The capabilities combining NIRS ASCA were demonstrated by studying effects sampling site year on 180 Austrian wheat samples across four sites over three years. It found that year, sample...

Abstract Background Recent gastroenterology studies assume that amylase-trypsin inhibitors (ATIs) and FODMAPs (fermentable oligo-, di-, monosaccharides polyols) play an important role in promoting wheat sensitivity. Hitherto, no study has investigated the formation of ATIs during development caryopsis. We collected caryopses common cv. ‘Arnold’ at eight different grain developmental stages to compositional changes ATI FODMAP content. Results The harvested were analysed for their size,...
