Detecting bacterial spores in soup manufacturing

10 September 2009 | By A.C.M van Zuijlen & S.J.C.M Oomes, Unilever R&D; P. Vos, Check-Points B.V. and S. Brul, University of Amsterdam

Spores from mesophilic aerobic sporeforming bacteria (Bacillus) are sometimes able to survive the thermal process of commercial sterile products and sporadically cause spoilage or food poisoning. Because of an increasing demand for more fresh products, ideally the processing temperatures should be tailored to inactivate the actual spore load rather than…

Hyperspectral chemical imaging maps food composition in laboratory and on-line

10 September 2009 | By T. Hyvärinen & H. Karjalainen, SPECIM, Spectral Iimaging Ltd; D. Nilsson, Umbio AB and K. Lynch, Gilden Photonics

Hyperspectral imaging combines digital imaging with precise spectral information in each image pixel. It enables composition mapping in food and agricultural raw materials and products based on differences in the spectral signatures of the various chemical ingredients. Advances in hyperspectral cameras and image processing solutions are now making hyperspectral imaging…

Online detection of foreign bodies in packaged foods using ultrasound

10 September 2009 | By Gauri S. Mittal, Professor, School of Engineering, University of Guelph

The presence of foreign bodies (FBs) in processed foods is one of the major concerns of the food industry, and their detection and identification are important in quality assurance and safety. An FB is any undesirable piece of solid matter present in a food product. When foods are manufactured or…

Use of molecular techniques in the food industry

1 June 2009 | By Mieke Uyttendaele and Andreja Rajkovic, Laboratory of Food Microbiology and Food Preservation, Ghent University

Microbial analysis in foods is an integrated part of management of microbial safety in the food chain. Both competent authorities and individual food business operators use microbial analysis for monitoring of the actual situation and trend analysis in order to detect emerging risks. For compliance testing to defined microbiological criteria…

New developments in low field NMR for the characterisation of food microstructure

1 June 2009 | By Matthieu Adam-Berret and François Mariette, Cemagref & Université européenne de Bretagne

Fats are present in most food products and they have a significant importance for fat-containing products such as chocolate and butter. The physical properties of fats depend on the polymorphic behaviour and inter-solubility of their major triacylglycerol components and the phase behaviour of these mixtures is of paramount importance for…
