Food processing can be considered as a set of practices – using defined technologies and techniques, either individually or in combination, to transform raw foods / food ingredients into food ready for consumption. Some basic techniques of food processing are for example drying, curing, smoking, fermentation, canning, pasteurisation (by heat…

Today, consumers are demanding high quality, fresh tasting foods free from additives, microbiologically safe and with an extended shelf-life. The most commonly used preservation method has been thermal processing, such as pasteurisation and sterilisation. However, these processes entail considerable organoleptic and nutritional quality losses. Food scientists and the food industry…

This article highlights the possibility of using molecularly imprinted polymers (MIPs) for the selective extraction of mycotoxins in food, instead of immunoaffinity columns which are based on the binding of an analyte, to the corresponding antibody. An overview of MIPs, developed for mycotoxin analysis, will be presented.

Meat quality has many different meanings. To some, quality refers to aspects of the carcass in respect to weight, fat cover and distribution, muscling/conformation and bruising. To others, quality refers to aspects such as chiller assessment attributes ie. meat colour, intermuscular fat colour and marbling. In pork, the attention of…
Important tasks of the fruit juice industry are to protect the good and healthy image for its whole product range and protect the market against any unserious producers. In order to assure fair competition, safe products and consumer satisfaction, the fruit juice industry has installed independent and centralised control bodies…

Foods such as guacamole, whole shell oysters, salsa, ready-to-eat meats, jams and jellies, salsa, chopped onions and peppers can be found in the global marketplace and are processed to some extent using high hydrostatic pressure. Essentially, this means the products have been submersed in water and then subjected to compression…

Ready-to-eat, fresh-cut consumer products are one of the few segments within the industry that has shown consistent growth within the last few years. Cutting however, increases senescence rate and the shelf life of the products can be very limited. Modified atmosphere packaging (MAP), combined with a good cold chain can…

The determination of organic trace compounds in food analysis is of major importance for food quality and food safety aspects. Both the separation of the analyte from potential inferences in the food matrix, as well as the qualitative and quantitative determination of the target compound, are vital steps in analytical…

Food manufacturers face challenges in optimising speed and efficiency, reducing product inventory, simultaneously responding to microbiological and chemical contaminants and entering the production process, via ingredients or the environment. Currently, most official or reference methods for pathogen or contaminant detection are laborious, costly, and often take a long time (3-7…

In 2004, the systematic non-compliance of lids for glass jars packed with oily foods was detected and compelled authorities to factually lift existing rules. This shows that not all industry performs satisfactory self control. It was a regulatory disaster and might, 4 years later, end in another regulatory disaster, if…

Appearance is an important factor, determining the perceived product quality. Consumers usually develop strong associations through appearance and often, base their pre-purchase judgements on the appearance of the product. Colloids, because of their ability to interact strongly with light, either in simple form or organised in more complex structures, offer…

You most probably rely on it for the operation of your food processing and storage systems – but how much do you know about your refrigerating equipment and the environmental obligations you have for the refrigerant they contain under UK law?

During manufacture, food can be exposed to microbiological cross-contamination from surfaces and air which may give rise to food spoilage and safety issues. The traditional approach to controlling such contamination has been to target specific sites within the manufacturing environment with cleaning and disinfection regimes.
