For food processing applications, ohmic heating may be defined as a process where an electric current is passed through the food with the main purpose of heating it. Under these circumstances, heat is internally generated due to the food's electrical resistance1 and this simple fact is responsible for the particular…

Some of you may have read details of the standard ISO 21469 which covers ‘Safety of Machinery - Lubricants with Incidental Product Contact - Hygiene requirements,' and may wonder why the food industry or the lubricants industry need yet another standard to which they should adhere.

Application of thermal heat in today's industrial scale food production and preservation is still the most commonly used processing technique, yet thermal treatment of foods affects their physical and chemical properties severely, which is often not intended but inevitable in order for sufficient preservation. Usually, sensorial appearance (colour, flavour, structure)…

The process technology landscape in the chocolate industry has changed markedly over the last decade. Following the key business trends, research and development in most organisations has incorporated all the key ‘buzzwords', with focus given to terms such as efficiency, speed, low cost, flexibility, trade secrets, patentability, open innovation and…

Increasing interest by consumers, producers and retailers in food safety, supported by several regulations of the European Commission (e.g. EC-regulation 178/2002; EC-2073/2005 amended by EC-regulation 1441/2007), gives accurate shelf-life determination of products a new consequence. Although there is rapid progress in food processing and new concepts such as predictive microbiology…

Moulding and demoulding is a processing operation commonly used in the manufacturing of candy and confectionary products for two main purposes: setting and shaping/forming. During moulding, a food material in the form of either flowable fluid (such as a melted sugar solution, a melted gel, etc) or semi-solid (such as…

Consumers today make well-informed choices about the food products they purchase. Savvy shoppers have access to a wealth of information and select their products based on brand recognition, nutritional labelling and differentiating attributes such as Certified organic, allergen-free and fair-trade. The food processing industry must continually evolve to keep pace…

Globalisation has been a significant factor behind the financial meltdown in which we all find ourselves now, but it has also led to significant changes in the variety and origin of the foodstuffs which line our supermarket shelves. In previous articles, I have discussed some analytical responses to the concerns…

In the mid-nineties, genetically modified crops (GM) that had been obtained through recombinant DNA technology were grown commercially at a large scale for the first time. The agricultural area that is covered with these crops has since then grown steadily, reaching 114 million hectares globally in 20072. GM crops and…

Consumers prefer food products, convenience products and ready-to-eat meals to have the taste of being freshly made. Moreover, it must be nutritious, safe, of high quality and originate from sustainable production. High-pressure (HP) technology can be utilised to its full potential as a minimal processing method to address consumers preferences…

The consumers want to see the product they are purchasing. The shops use special lighting in order to sell more, at the same time as prolonging the opening hours. The price the consumer pays for the combination of increased light exposure and the desire to see food products is that…

Since the introduction of atmospheric pressure ionisation liquid chromatography-mass spectrometry (API-LC-MS) in the early 1990s, there was a continuous effort to further improve the performance of the LC-MS instruments concerning sensitivity and robustness. One result of this development is the trend towards methods that are designed to simultaneously analyse a…

This paper argues the case for increased awareness of the importance of training and competence in management of food and water safety, prevention of food-borne and waterborne illnesses and improvement of health and nutritional status. The challenge is huge as almost everyone needs to receive education commensurate with his or…
