‘Nano’ or small-scale technologies are an exciting area of science involving work at the nano scale; far smaller than micro-scale technology and impossible to view with the human eye. No-one yet knows the extent to which nanotechnology could transform our world, but it is generally acknowledged that the technology could…
In the last 30 years, membrane processes have become major tools in the food industry.1,2 This industry represents the second sector of membrane applications, after water treatment, and on equal terms with pharmaceutical and biotechnology applications.

Did you know that Finland is the leader in functional food innovations? It seems as though the Finns turn their weaknesses into strengths; they may not be very talkative, but they are leading producers of mobile phones, and they may not have a very rich food tradition, but they are…

The past ten years have seen many changes in both food science and technology as well as in food regulations. Contrary to the decades before then, most of it has been consumer driven. Consumers have become more aware of the influence of eating habits on their lives, in particular their…

Shortly after Reading Scientific Services Ltd formed its Emergency Response Service (ERS) in 1987, the UK food industry faced one of the biggest, and most public, extortion attempts ever to occur. A former Metropolitan police detective, Rodney Witchelo, had begun his campaign to extort money by contaminating jars of baby…

The Danish swine industry produces more than 20 million slaughtered pigs each year. For many years most of the production has been exported, with England, USA and Japan being some of the most important markets.

Refrigeration is a vital part of modern food production. Without a means to cool and keep food cold, the quality and safety of food would be compromised and the sophisticated cold chain we are used to would not be possible. The whole food chain is underpinned by refrigeration from primary…

Food packaging is traditionally required to have many functions: to contain and protect the food, to provide a surface for information labels, to add a distinct brand identity and to present the food attractively so that consumers will purchase it.
Titration is an analytical technique that is widely used in the food industry. It allows food manufacturers to determine the quantity of a reactant in a sample. For example, it can be used to discover the amount of salt or sugar in a product or the concentration of vitamin C…

Food preservation implies that micro-organisms are inactivated or suppressed in order to enhance the safety and quality of the product. Alternative physical techniques aim to combine the stability and microbial safety of foods with a minimal loss of quality attributes. Because these techniques have little or no thermal effects on…

Most solid foods are heterogeneous on one level or another. Minced meat or an intact piece of meat, for example, will have smaller or larger local regions that are almost pure fat, pure lean meat or pure connective tissue. For such heterogeneous foods the distribution of the local differences is…

This article focuses on the main principle of the liquid chromatographic tandem mass spectrometric (LC-MS/MS) determination of mycotoxins in foodstuffs. It also provides an overview of recent developments in mycotoxin analysis.

The colour and appearance of baked products are important quality attributes. Printed images of products are often displayed in production areas to illustrate the required appearance, but frequently provide a poor match to the actual product colour.Calibrated imaging methods are now available that enable accurate, consistent images to be taken…

There are many naturally bioluminescent organisms existing in nature and the mechanisms whereby some of these creatures emit light have been fully characterised1. These include the luciferin-luciferase system of bacteria, insects (fireflies and click-beetles) and the jellyfish Aequorea victoria. In essence, bioluminescence involves the conversion of chemical energy into light…

The evaluation of shelf life of perishable foods is a key aspect of modern production and distribution. Food ‘freshness’ is one of the most required attributes by consumers and is strongly influenced by storage conditions – temperature abuse being one of the main factors affecting the shelf life (Labuza, 1982;…
