Odours can be complex: different forms of the same molecule of carvone, for instance, can smell like either spearmint or caraway. While the human nose can easily distinguish between these two smells, until now, machines haven't been able to.
Milk Orange: sounds like a bizarre new brand of flavoured milk. In fact, it's the world's first fluorescent sensor that rapidly measures the level of fat in milk.
Cheap electronic circuits printed with eco-friendly materials could take the guesswork out of knowing whether milk is actually out of date or whether it has a day or two left - no smelling required.
Researchers have developed a low-cost 'e-tongue', an electronic 'tongue' that could one day sample food and drinks to check for quality before they hit the shelves - or even monitor water for pollutants.
The good old litmus test has been adapted to detect pathogens such as E. coli in liquids. A research team set out to make testing liquids faster, easier and more affordable by using litmus dyes and paper to detect the presence of bacteria.
state of conservation of poultry and detects malformations by analysing its electrical properties. It is a non-invasive system that would help to guarantee the quality of the final product before it is delivered to the consumer.
The Retsch Camsizer system for the determination of particle size and particle shape has been upgraded. Compared to the previous model, the analyser has faster cameras with higher resolution, a stronger light source and new software features.
Mexican researchers have developed a microbiosensor that detects beneficial bacteria in food. The micromechanical device has been used to evaluate the growth of L. plantarum 299vm.
Malaysian researchers are developing a testing kit that identifies non-halal ingredients within one minute. The kit, developed by the University of Selangor, can be used to test food, cosmetics and medicines.
Researchers from Universiti Teknologi MARA in Malaysia have developed a PCR kit that provides a sensitive and specific means of screening, detecting and identifying sarcocystis spp.
Kansas State University master's student Lance Noll has developed and validated a molecular assay that can detect and quantify major genes specific to E. coli O157.
Research presented at the Society for General Microbiology's annual meeting shows that the disease-causing E. coli O157:H7 interacts directly with plant cells, allowing it to anchor to the surface of a plant where it can multiply.
To combat food fraud, we need to identify which factors play a role in vulnerability of organisations and the food chain, according to Saskia van Ruth, the newly appointed Professor of Food Authenticity and Integrity at Wageningen University.
A new study may have cemented hospital food's bad reputation. The study found that more than 80% of raw chicken in hospitals was contaminated with an ESBL-producing E. coli strain which is resistant to antibiotics.
Non-destructive food quality testing could soon be a reality, thanks to researchers from the University of Western Australia. The technique is similar to using infrared thermometers to detect body temperature.
