Occurrence, toxicology and strategies for reducing acrylamide levels in foods

4 July 2012 | By Monica Anese, Department of Food Science, University of Udine

The discovery in 2002 that cooking of various foods at high temperature (exceeding 100°C) results in the formation of high levels of acrylamide1 has caused considerable concern because this compound has been classified as ‘probably carcinogenic to humans’ by the International Agency for Research on Cancer2. In fact, acrylamide levels…

Progress on coffee roasting: A process control tool for a consisten roast degree – roast after roast

4 July 2012 | By Chahan Yeretzian, Flurin Wieland & Alexia N. Gloess, Zurich University of Applied Science, Institute of Chemistry and Biological Chemistry and Marco Keller, Andreas Wetzel & Stefan Schenker, Bühler AG

A real-time automated process control tool for coffee roasting was developed to consistently and accurately achieve a targeted roast degree. It is based on timeresolved on-line monitoring of volatile organic compounds (VOC) in the off-gas of a drum roaster, using Proton-Transfer-Reaction Time-of-Flight Mass-Spectrometry (PTR-TOF-MS). These experiments provide a detailed, real-time…

Microbial biofilms – a concern for industry?

3 July 2012 | By Dr Evangelia Komitopoulou, Head of Food Safety, Leatherhead Food Research

Many bacteria are able to attach to and colonise environmental surfaces by producing a biofilm, which allows the organisms to persist in the environment and resist desiccation, UV light and treatment with antimicrobials and sanitising agents. Biofilms are formed when microbes attach to a solid support and to each other…
