Renowned for its ‘postcard’ lake-side setting surrounded by snow-capped mountains, the beautiful French town of Annecy is perhaps less well known as the home of famous regional raw cows’ milk cheeses, such as Reblochon and Tomme. Controlling the quality of these cheeses and the raw milk used to produce them,…

The UK cheese market is now worth £1.7 billion per annum and, despite being a very mature product that’s already consumed in 98 per cent of UK homes, its growth shows little sign of slowing. The whole category is being driven forward by a wide range of domestic manufacturers producing…

The process used for commercial ice cream manufacture has changed little in the past 75 years – since the first continuous scraped surface freezer was introduced in the 1930s. In recent years, however, several key technological developments have taken place in the way ice cream is manufactured and these are…

Modified atmosphere packaging (MAP) of fish extends the shelf life of high quality products at low temperatures by inhibiting bacterial growth, oxidative reactions and unwanted components such as TMA (trimethylamine). CO2 is the most important gas used in MAP because of its negative effect on bacterial growth. An initial alteration…

Increasing microbial safety and extending the shelf-life of packed food and other products sensitive to microbial spoilage is often performed by relatively slow thermal processes. The adverse effects of the corresponding heating periods can be decreased by using technologies that put a vast amount of energy into the product quickly,…

Pressure from consumers has forced manufacturers to take greater care and be even more accountable for their products. This requires assurance at every level of the supply chain and particularly within the factory. Mandy Drabwell investigates how food grade lubricant manufacturers are playing their part in meeting the challenge. All…

The demands that are placed on product and process within the food production industry are interconnected. Therefore, it is not appropriate to use a largely sequential approach to designing a production facility, where you first address the primary function of the product, i.e. product quality and then consider other issues…

In recent years a wide-reaching recognition of the importance of production consistency and quality has emerged in the food industry. With the recent recognition by the American Food and Drug Administration (FDA), Process Analytical Technology (PAT) has become the key issue in statistical process design, monitoring and control for pharmaceutical…

During the last 25 years, there has been a steady evolution in the way the food industry organised itself to ensure delivery of safe and consistent quality food to the consumer. In the late 1970s, it was still common to see extensive laboratories in factories with large numbers of people…

Advances in food science, product development and analytical chemistry continuously drive the need for state-of-the-art food safety evaluations by both the food industry and regulators. Considering the scope and complexities involved in this process, industry and regulators are beginning to form collaborations to enhance the food safety evaluation process and,…

In trying to understand the functionality of food materials, the microstructure has been universally recognised as important – hence the wide use of various forms of microscopy in food science. Conventional light microscopy is well developed and widely used in characterising food structures (J.G.Vaughan 1979). The next level of information…

NIR is widely used in food analysis with application to many sectors. In this article Gerry Downey addresses its value to the dairy industry. The dairy industry is of enormous financial significance in Ireland and many other European countries and it is currently undergoing a period of large scale rationalisation…

A new technique for the detection of transmissible spongiform encephalopathies, such as scrapie in sheep or BSE in cattle, is based on IR (infrared) spectroscopy of serum and subsequent spectral analysis by advanced pattern recognition techniques. Within the scope of two validation studies, IR spectra from sera of scrapie-infected Syrian…

The microbiological analysis of food has an important role in assessment of the quality and safety of foods. There is a direct relationship between bacterial numbers and product shelf life as growth of bacteria can result in organoleptic changes in the food, including off-colours and off-odours, rendering it unacceptable to…
