While considerable effort has been expended to reduce the presence of Listeria monocytogenes in the food processing industry, new research suggests that contamination may be occurring at the retail level.
The Mecmesin MultiTest-i range of compressive and tensile test stands is particularly suited to the laboratory environment. They are available in a range of capacities.
Up to 30% of seafood is mislabelled when it enters the US, with unscrupulous dealers naming other species as grouper, for instance. Scientists have developed a handheld sensor that can bust mislabelled fish, even when it's cooked.
John Morris Scientific has announced the release of two Martin Christ benchtop freeze dryers: Epsilon 1-4 LSCplus and Epsilon 2-4 LSCplus.
Texas Tech researchers have discovered a new serotype of the Salmonella bacteria. The serotype was confirmed by the Pasteur Institute in Paris, the international reference centre for Salmonella.
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circuits printed with eco-friendly materials could take the guesswork out of knowing whether milk is actually out of date or whether it has a day or two left - no smelling required.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.
