Optimal drying is no easy task

18 August 2008 | By Maarten Schutyser, Maykel Verschueren, Han Straatsma, Hadiyanto, Coen Akkerman, Peter de Jong, NIZO food research

Drying processes in the food industry often operate at a suboptimal level. The most important reason for this is that to obtain optimal drying, a complex balance must be found among variables such as energy costs, product quality, dryer design and safety. Therefore, there is a need for a systematic…

Measurement of water dynamics by low-field NMR

18 August 2008 | By Dr Hanne Christine Bertram. Senior Project Scientist, University of Aarhus

Water is a major constituent in many foods. For example, in several of our basic food items such as muscle-based foods and vegetables, water is the dominating component and is in many ways of primary importance for the quality of these products. Low-field proton NMR relaxometry is an excellent technique…

Mapping food composition using NIR hyperspectral imaging

18 August 2008 | By S.J. Millar, M.B. Whitworth, A. Chau, Campden & Chorleywood Food Research Association and J.R. Gilchrist, Gilden Photonics Ltd

Near infrared (NIR) spectroscopy is widely used in the global agri-food industry for the non-destructive assessment of both the compositional and physical characteristics of a wide range of raw materials and finished products. This is particularly so in the cereals and related industries where, following the commercial development of suitable…

A perspective on actual technologies and future developments

18 August 2008 | By Giuseppe Mensitieri, University of Naples Federico II and Giovanna Giuliana Buonocore, Institute for Composite and Biomedical Materials – National Research Council

In this contribution, the topic of Modified Atmosphere Packaging (MAP) is reviewed by describing the actual status of this technology and its possible developments, which are mainly related to the combination of MAP with other preservation technologies. Among them, particular attention is devoted to active packaging with antimicrobial properties.

The risks of psychrotrophic Clostridium botulinum in MAP and vacuum packed chilled foods

18 August 2008 | By Greg Jones, Senior Research Officer for the Preservation, Processing and Spoilage Group, Campden & Chorleywood Food Research Association

Foodborne botulism is a severe illness that is caused by the consumption of foods containing a neurotoxin produced by a bacterium called Clostridium botulinum. Very little of this toxin is required to cause illness; for example, in 2002, a 35 year old man put a piece of baked potato in…

An introduction to food safety and HACCP law

18 August 2008 | By Carol Wallace, Principal Lecturer, University of Central Lancashire and Sue Powell, Co-ordinator for the North West Teaching Public Health Network

All businesses need to make sure that they operate within the law for a wide range of measures, including health & safety, environmental issues, weights and measures, et cetera. For food businesses, it is crucial that the food sold does not endanger public health, therefore adequate control systems must be…

Breathing new life into hydrocolloids

18 August 2008 | By Dr Pretima M. Titoria, Section Manager: Ingredients, Leatherhead Food International

Food and drink manufacturers are under relentless pressure from consumers to produce products that can not only deliver exciting textures and tastes, but can also be healthy and shelf-life stable. This is then reflected in the challenge posed to the hydrocolloid suppliers and manufacturers, who must deliver thickeners, stabilising agents…

Pasta is recognised as a family menu staple because it offers a number of unique benefits that other foods do not, such as a broad taste appeal, the versatility of usage, the convenience of preparation and being an inexpensive alternative to other main entrees.

IFR: the future on a plate

13 June 2008 | By Zoe Dunford, Media Relations & Science Writer, John Innes Centre and Institute of Food Research and Professor Tim Brocklehurst, Head of Microbial Ecology Platform & Head of the IFP Food and Health Network, Institute of Food Research

IFR is publicly funded and can undertake the kind of long term fundamental research that cannot economically be undertaken by industry, but will lead to product and processing innovations in years to come. Past breakthroughs include pioneering work in the 1930s on controlled atmosphere storage to enable the transport and…
