• Comparison study of conveyor belt materials
  Author: Satu Salo, VTT Technical Research Centre of Finland
  Food safety is dependent on several factors and one important issue is the hygiene of food contact surfaces in food factories. Regarding cleanability and disinfectability, no common regulations are available in EU for the food contact material surfaces. In hygiene regulation EC 852/2004 (EC, 2004a), the requirements are general and control authorities do not require certificates providing evidence for the compliance with the regulation. An ideal food contact surface would be easy to clean and disinfect; the rougher the surface, the more readily soil particles will adhere to it, resulting in adverse effects on the cleanability of the surface…
• Mineral oil from recycled paperboard: recent progress
  Author: Koni Grob, Official Food Control Authority of the Canton of Zurich
  In 1989, the European Scientific Committee on Food (SCF), the predecessor of the EFSA, evaluated mineral oil and established a temporary tolerable daily intake (TDI) of 0.005-0.05 mg/kg body weight (bw) depending on oil quality. Using the usual assumptions this relates to migration limits of 0.3-3 mg/kg food. As the mineral oil migrating from recycled board contains 15 – 20 per cent mineral oil aromatic hydrocarbons (MOAH), the lower limit applied, which was usually exceeded roughly 100 times…
• In-pack electrical mild preservation techniques for liquid food products
  Author: Bart Roodenburg, Researcher, Delft University of Technology
  Microorganisms are the main cause of food spoilage and foodborne diseases, therefore most products are pasteurised. Thermal pasteurisation, which is one of the most common preservation techniques, strongly affects the original taste of these products. The deterioration in taste is mainly caused by a too high heat-load during processing. In the past decade, there has been increased consumer demand for more fresh-like products with an extended shelf life (e.g. for fresh squeezed fruit juices). For that reason, several electrical mild preservation techniques have been developed. A valuable and logical next step would be the development of a post-packaging variant of these techniques. This could, for instance, eliminate the need for aseptic packaging. Figure 1 shows an overview of the most common mild preservation techniques and their main operating principle. Three of them have a direct electrical origin…
