NIR and class-modelling methods for brand protection in food and beverages

6 September 2011 | By Professor Gerard Downey, Teagasc Food Research Centre Ashtown

The penetration of on-line NIR equipment in the food processing industries continues to grow as companies realise the full potential of this technique. For the most part, it is deployed to monitor concentrations of key components in a raw material or finished food product and, with the use of feedback…

Profiling of intact wheat arabinoxylans by spectroscopy

6 September 2011 | By Gwénaëlle Le Gall, Peter R. Shewry, E.N. Clare Mills and Geraldine A. Toole, Institute of Food Research

Wheat is the most widely grown cereal in the world and is used to make a variety of baked goods, such as bread, biscuits, pasta, noodles and breakfast cereals. On hydration of flour to make a dough, the seed storage proteins form a cohesive mass known as gluten. This protein…

Stability of pork during frozen storage

6 September 2011 | By Lene Meinert, Consultant, Danish Meat Research Institute

Freezing is a well-known and widespread preservation method, prolonging the shelf-life of meat and many other food items. Freezing is popular, as it allows meat to keep a close-to-fresh quality for a long time, and it also allows long distance transports. However, depending on the time and temperature combinations during…

6 September 2011 | By Graham G. Stewart, GGStewart Associates and the International Centre of Brewing and Distilling, Heriot-Watt University

While the basic processes of malting, brewing and distilling were established long ago, it was in the late 19th century that the key scientific investigations commenced on beer and its production through the pioneering work of scientists such as Pasteur, Hansen, Sorenson, Brown and decades of subsequent research on process…

Emerging challenges and trends in UHT processing of milk and other dairy products

6 September 2011 | By Marina Witthuhn, Jörg Hinrichs and Zeynep Atamer, Universität Hohenheim, Institute of Food Science and Biotechnology, Department of Dairy Science and Technology

In order to obtain safe dairy products with a long shelf-life, heating processes have been designed to ensure the necessary inactivation of the indigenous microbial flora. One of the methods is the ultra-high temperature (UHT) processing of milk which has become widespread since the implementation of aseptic packaging processes1. Nowadays,…

The optimisation of freeze drying processes

6 September 2011 | By Javier Silanes Kenny, Associate Principal Scientist, Soluble Coffee Process Optimisation, Kraft Foods

From its infancy to today, lyophilisation has seen a constant but very slow evolution. Indeed, the techniques that we utilise today differ very little to those used industrially, after its development as a viable technique for the preservation of serum during World War II. Its application to pharmaceuticals and from…

Highly competitive retailers constantly squeezing down prices, rising raw material costs and soaring utility charges in a labour-intensive manufacturing environment; why shouldn’t food manufacturers look towards automating their manufacturing processes? Automating food production can reap many benefits. The ability to replicate the appearance and quality of a product with the…

Chocolate aeration – Art or science?

6 September 2011 | By Josélio Vieira, Principal Research Scientist, Nestlé Product Technology Centre and Venkata R. Sundara, Group Leader for Aerated and Filled Confectionery, Nestlé Product Technology Centre

Bubble inclusion into chocolate results in a foam in which the gas is dispersed in the continuous fat phase of mainly cocoa butter, which also contains sugar, cocoa and milk powder particles. Aeration allows chocolate products to have a low weight in relation to volume, thereby reducing the calories in…

Rapid and automated screening of priority β-agonists in urine using high resolution LC-MS technology

6 September 2011 | By Thorsten Bernsmann and Peter Fürst, Chemical and Veterinary Analytical Institute, and Michal Godula, Thermo Fisher Scientific

Beta-agonists (β-agonists) are synthetically produced compounds that are widely known for their bronchodilatory and tocolytic effects. At higher doses, these substances also have anabolic effects and can promote live weight gain in food producing animals. Clenbuterol is the most commonly used β-agonist for growth-promoting purposes, despite the fact that there…
