Fluid flow in cleaning of closed processes

9 March 2006 | By Assistant Professor Bo Boye Busk Jensen and Associate Professor Alan Friis, Food Biotechnology and Engineering, BioCentrum-DTU

The efficiency of Cleaning-In-Place (CIP) procedures greatly depends on fluid flow (i.e. the motion of detergent and rinsing water). Thorough understanding of the physical action of fluid flow during cleaning allows for redesign of equipment and design of CIP procedures with respect to optimal cleaning characteristics. This article discusses the…

Innovative uses of NIR to improve baking

21 November 2005 | By Dr. Richard Dempster, American Institute of Baking

Near Infrared Reflection (NIR) is an established and valid measurement method for many specific compounds, (moisture, protein, fat, etc.) within the food industry. Recently, two ideas have emerged from the American Institute of Baking (AIB). The first is to use NIR to monitor processes and the second is to use…

Bran, bread and bubbles

21 November 2005 | By Grant M Campbell, Satake Centre for Grain Process Engineering, School of Chemical Engineering and Analytical Science, The University of Manchester

The greatest challenges facing the domestic chef or his/her industrial counterpart frequently concern the creation, retention and control of aerated structures in foods. Many food products – and most of the more high profile and attractive ones – derive their distinction and appeal from the incorporation and manipulation of bubbles:…

Standard for food safety management

21 November 2005 | By Jacob Færgemand, Project Leader, ISO 22000 working group

Food safety hazards may be introduced at any stage of the food chain and adequate control throughout the food chain is therefore essential. Thus, food safety is a joint responsibility that is principally assured through the combined efforts of all the parties participating in the food chain.

Why is microstructure important in food systems?

21 November 2005 | By Peter Edmondson, Cadbury Trebor Bassett Ltd

Traditionally the food industry’s aim has always been to produce safe, convenient, good quality foods in sufficient volume to feed a growing and prosperous population. In the past food processes have been designed using practical experience. This has involved the culmination of the knowledge of product quality requirements, such as…

Considering hygiene in food factories

21 November 2005 | By Mandy Drabwell, New Food

Well informed consumers demand the highest quality food, which means fresh, nutritious, safe products. It is in the manufacturers’ interest to ensure that their products reach consumers in perfect condition and that – at the very least – it is safe to consume. Of course, this feat requires careful attention…

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…

Where is the nut oil in chocolate?

29 July 2005 | By Greg Ziegler and Kristin Szlachetka,Cocoa, Chocolate and Confectionery Research Group, Department of Food Science, Penn State University

Oil migration is responsible for the poor keeping qualities of many composite confectionery products with nut-based centres, coated biscuits, or nut inclusions. Quality defects arising from oil migration include softening of the coating; hardening of the filling; deterioration in sensory quality and a greater tendency to fat bloom. For this…

Implementing food safety and hygiene

29 July 2005 | By Dr Ken Burgess, Technical Director, Dairy Crest

Responsibility for safety from ‘farm to fork’ is obviously shared between farmers, manufacturers and processors, distributors, consumers and various government authorities. The perspective of the manufacturer is in ensuring that known food safety risks are managed and controlled, while the areas of new and emerging food safety risk have traditionally…

The benefits of automated pathogen testing

3 May 2005 | By Eric Maucci, Food Hygiene Technical Manager, Laboratoire Inter-Départemental des Analyses Laitières (LIDAL)

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,…
