Innovative packaging for UHT

21 November 2005 | By Paulo Bonometti, Technical Director, Centrale del Latte di Brescia Spa

In the field of food packaging it is particularly important to guarantee correct preservation of the product. This means that the food product, during its shelf life and prior to consumption, must retain its nutritional properties and organoleptic characteristics. Also, consumers prefer practical packaging. When considering liquid food, for example…

Detecting Salmonella antibodies in pork

21 November 2005 | By René Achterberg, Judith Maneschijn-Bonsing, Rinus Bloemraad, Manon Swanenburg and Kitty Maassen, Animal Sciences Group, Lelystad, The Netherlands

Programs for monitoring Salmonella in the pork production chain have begun in several European countries. For an assay to be used in a monitoring program, it is a prerequisite that the total testing time per sample is short and that regeneration is optimal. In collaboration with a major pork producer…

Dealing with decontamination

21 November 2005 | By Christian James, Food Refrigeration Process Engineering Research Centre, University of Bristol

There is no terminal step (such as cooking) to eliminate pathogenic organisms from raw meat before it reaches the consumer. The consumer is relied upon to ‘adequately’ cook the meat so that any pathogens that may be present are killed. Many studies have shown that at the time of slaughter…

Bacterial tolerance – the consequences

21 November 2005 | By Even Heir and Solveig Langsrud, Matforsk AS, Norwegian Food Research Institute, Norway

Failure in cleaning and disinfection increases the ability of bacteria to survive, adapt and establish in food processing equipment or other environments, with the potential to transfer to food products. The antimicrobial effects of disinfectants depend upon several factors. This article focuses on the properties and mechanisms of bacteria involved…
