Our previous study of spices was designed to evaluate the metal content in the spices for evidence of contamination by heavy metals or for adulteration and counterfeiting by notable concentrations of wear or additive metals. This study targeted the same spice samples to quantify the characteristic primary and secondary market compounds for each spice group.

With greater portability than real-time PCR instrumentation, the AmpliFire produces rapid and accurate results in the field or in the lab without cumbersome equipment or reagents. In a recent study, the AmpliFire® accurately detected the presence of Salmonella enterica using both purified genomic DNA and a crude sample preparation method, making it a powerful tool for point of use applications.

Nucleic Acid Testing (NAT) is a powerful tool for the quantification of microorganisms and are used in many fields. In this study commercially available microbial NAT kits were successfully miniaturized from 20 µL to 1.6 µL reaction volumes using the IntelliQube. The IntelliQube delivers efficient and economical high throughput sample processing for microbial qPCR applications.

As many biodetection assays, especially nucleic-acid based tests, require a more or less complex sample preparation protocol, microfluidics is seen as one of the key enabling technologies to realize the integration of these sample prep protocols with the detection scheme on a single device.

In this work, we will present the fundamentals of Foodomics, discussing the role of this new discipline to solve some current and future challenges in food science and nutrition, and showing several Foodomics applications carried out in our laboratory related to food quality and food bioactivity.

We report a more-than-six-year experience with food oral immunotherapy (FOIT) in a private allergy practice setting. Most patients can be desensitized to one or more allergenic foods. Ongoing evaluation and modification of the FOIT procedures improves outcomes and acceptability. FOIT can be successfully performed in an allergy office.

Changes in gastrointestinal microbiota have been suggested to drive the increasing prevalence of food allergy. Our aim was to determine the impact of mouse and human intestinal microbiota on modulation of allergic parameters including IgE.

The expanded measurement uncertainty of a sample preparation method based on QuEChERS procedure for the determination of fumonisin B1 in four types of rice, using HPLC-FLD after precolumn derivatisation with ortho-phthaldialdehyde, was estimated from in-house validation data.
