Development of a DNA Barcoding-Like Approach to Detect Mustard Allergens in Wheat Flours.

The spread of food allergens is a topic of global importance due to its impact on public health. National and International regulations ask food producers and manufacturers to declare product compositions on the label, especially in case of processed raw materials. Wheat flour () can be contaminated by a wide range of species belonging to the Brassicaceae in the field or during grain harvests, storage, and processing.

Ion mobility spectrometry coupled to gas chromatography: A rapid tool to assess eggs freshness.

Egg products freshness is a crucial problem for the production of safe and high quality food. Ion Mobility Spectrometry (IMS) coupled to Gas Chromatography (GC), provides a rapid, sensitive, cost-effective tool for the detection of freshness issues. A chemometric model was created recording the volatile fingerprints of the different egg products batches, analyzed as fresh, then left at room temperature and daily controlled: 97% was correctly predicted by the model.

Determination of Ochratoxin A in Rye and Rye-Based Products by Fluorescence Polarization Immunoassay.

A rapid fluorescence polarization immunoassay (FPIA) was optimized and validated for the determination of ochratoxin A (OTA) in rye and rye crispbread. Samples were extracted with a mixture of acetonitrile/water (60:40, /) and purified by SPE-aminopropyl column clean-up before performing the FPIA. Overall mean recoveries were 86 and 95% for spiked rye and rye crispbread with relative standard deviations lower than 6%.
