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…

Ingredients: Microencapsulation of food ingredients: still a field to be explored?

10 September 2009 | By Adem Gharsallaoui, Temporary Associate Professor, AgroSup Dijon (France)

The food industry uses more and more purified natural and synthetic fragile substances today, and consequently, there is an increased need to protect these ingredients. Functional food ingredients, such as flavours, vitamins or antioxidants, are sensitive to environmental stress during manufacturing, storage and consumption of the food product. Furthermore, loss…

One drop at a time: a revolution in drying evaluation technology

10 September 2009 | By Jakob Sloth, Research Scientist, GEA Niro

The ability to test products and processes has always been an essential part of new product development. Until now, food processing companies have had to conduct exhaustive tests to establish the most appropriate formulations to optimise taste and the manufacturing process. But now a new particle analysis process, pioneered by…

Ingredients: Modulation of saliva flow, saliva lubricating properties and related lingering perceptions by refreshing water ice consumption

10 September 2009 | By D. Labbe & N. Martin, Department of Food Consumer Interaction, Nestlé Research Centre

Refreshing in foods and drinks is a perception strongly related to mouth state after product consumption. Oral dryness and roughness are lingering perceptions negatively related to refreshing perception whereas mouth wetting perception is a positive driver of refreshing perception. Since saliva seems to be related to mouth wetting, we explored…

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…

Future applications for brewers’ spent grain

10 September 2009 | By Annika Wilhelmson, Pekka Lehtinen, Niklas von Weymarn, Merja Itävaara, Juhani Sibakov, Raija-Liisa Heiniö, Pirkko Forssell & Johanna Buchert, VTT Technical Research Centre of Finland

The brewery by-product Brewers' Spent Grains (BSG) is composed of the insoluble cereal residue that is separated from the mash before fermentation. It is estimated that the annual production of BSG is approximately 30 million tonnes worldwide. BSG consists mainly of the insoluble covering layers of the barley malt, i.e.…

Cisgenesis: a novel way to combat late blight

10 September 2009 | By Anton Haverkort, Senior Researcher, Wageningen University and Research Centre

In most countries with temperate climates, cereal, notably wheat, is the most important arable crop. In a few countries such as the Netherlands, potato dominates. In the European Union, over 50 million hectares of wheat is grown against approximately two million hectares of potato, yielding some 70 million tons of…

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…
