Non-invasive sensing for food reassurance
The main food quality traits of interest using non-invasive sensing techniques are sensory characteristics, chemical composition, physicochemical properties, health-protecting properties, nutritional characteristics and safety. A wide range of non-invasive sensing techniques, from optical, acoustical, electrical, to nuclear magnetic, X-ray, biosensor, microwave and terahertz, are organized according to physical principle.

Is food allergen analysis flawed? Health and supply chain risks and a proposed framework to address urgent analytical needs
Food allergy is an increasing problem. If we fail to realise the promise of current risk assessment and risk management of food allergens through lack of ability to measure them reproducibly and with traceability to an international unit of measurement, the analytical community will have failed a significant societal challenge.
Point-and-shoot: rapid quantitative detection methods for on-site food fraud analysis – moving out of the laboratory and into the food supply chain
Major food adulteration and contamination events occur with alarming regularity and are known to be episodic, with the question being not if but when another large-scale food safety/integrity incident will occur.

Over the past years, the application of electronic nose devices has been investigated as a potential tool for assessing food freshness.
Meat, the metabolites: an integrated metabolite profiling and lipidomics approach for the detection of the adulteration of beef with pork
Adulteration of high quality food products with sub-standard and cheaper grades is a world-wide problem taxing the global economy.
Multiplex surface plasmon resonance biosensing and its transferability towards imaging nanoplasmonics for detection of mycotoxins in barley
A 6-plex mycotoxin assay was developed on a portable nanostructured iSPR and compared with a benchmark double 3-plex SPR assay.

Reproducibility standard deviations from collaborative trials and from proficiency tests in the food analysis sector are compared and found to be closely similar over a wide range of mass fractions.
Assessing potato chip oil quality using a portable infrared spectrometer combined with pattern recognition analysis
The objective of this study was to evaluate the performance of a portable FT-IR spectrometer equipped with a 5-bounce heated ZnSe crystal to develop classification methods for the authentication of potato chip frying oils and to generate prediction models for monitoring oil quality parameters for real-time and field-based applications.

A simple, solvent-free extraction method for DNA facilitates the analysis for genetically modified organisms.
Chicken, beams, and Campylobacter: rapid differentiation of foodborne bacteria via vibrational spectroscopy and MALDI-mass spectrometry
This study is focused on the rapid differentiation of multiple Campylobacter species down to sub-species level, which may provide critical information and knowledge of risk factors, virulence, and distribution of these major foodborne pathogens.
A silica coated paper substrate: development and its application in paper spray mass spectrometry for rapid analysis of pesticides in milk
A novel silica coated paper substrate has been developed, which demonstrated a high capacity for direct analysis of pesticides in paper spray mass spectrometry.
Performance improvement and single laboratory validation of classical qualitative methods for the detection of adulterants in milk: starch, chlorides and sucrose
Simple modifications in classical methods for detection of milk adulteration were validated with significant performance improvement.

A new molecularly imprinted polymer (MIP)-chemiluminescence (CL) method has been developed for the detection of ethopabate (ETP) residues in chicken muscle.
A reliable and sensitive LCMS-IT-TOF method coupled with accelerated solvent extraction for the identification and quantitation of six typical heterocyclic aromatic amines in cooked meat products
A liquid chromatography-ion trap-time of flight tandem mass spectrometric assay coupled with accelerated solvent extraction was developed to identify and quantify six heterocyclic aromatic amines.
