Yeast forensics: methods for identification and tracking

3 December 2008 | By Dr Suzanne Jordan, ­Molecular Methods Manager, Campden BRI

Yeasts are a diverse range of organisms, many of which are beneficial to the food and drinks industry in fermentation and the flavour development of dairy, meat and beverage products. There are also strains that spoil products, resulting either in blowing packs or off odours and flavours.

New analytical approaches to investigate the fate of bisphenol A diglycidyl ether (BADGE) in foods

3 December 2008 | By Leon Coulier & William van Dongen, TNO Quality of Life and Emma Bradley & Laurence Castle Central Science Laboratory, York

Many new developments in analytical chemistry are driven by needs for life science applications. Examples are the various –omics technologies, i.e. genomics, transcriptomics, proteomics and metabolomics and the use of isotope labelling. Food analysis is often thought to be less complex when one thinks of the determination of specific contaminants…

Food safety: no room for complacency

3 December 2008 | By Professor Patrick Wall, Associate Professor of Public Health, University College Dublin

In the 1990s, a chronology of food scares, culminating in BSE, damaged consumer confidence in the safety of food, in the commitment of industry to produce safe food and in the ability of the regulatory agencies to police the food chain. These scares precipitated a review by many EU Member…

Nanotechnology in the food industry

3 December 2008 | By NF

Applications of nanotechnology in the food industry mean different things to different people and this influences the perception of benefits and risks of nanotechnology. Nanotechnology is not a discrete area, but rather a broad spectrum of applications concerned with the rational modification of food structures at the molecular or macromolecular…

Energy, nutrition and the quality of breads; an overview of ‘EU-FRESHBAKE’

3 December 2008 | By A. Le-Bail and R. Zuniga, ENITIAA – GEPEA; T. Lucas, Cemagref; M. Sikora, University of Agriculture Balicka; C. M. Rosell, IATA-CSIC; D. Curic, University of Zagreb; T. Park, TTZ-EIBT; V. Kiseleva, Russian Academy of Science, IBCP RAS; M. Pitroff, MIWE; I. Van Haesendonck, PURACOR; M. Bonnand-Ducasse, BIOFOURNIL; M. Koczwara, BEZGLUTEN; V. Cerne, SCHAER R&D

The European bread industry is using refrigeration more and more to extend the shelf life of bakery products. The associated technologies, called bake-off-technology, allows the retail of freshly baked breads made from industrial frozen (and non frozen) products. Energy used for bread making, nutrition facts and quality of the final…

The holy grail of a single food safety specification

3 December 2008 | By Kath Veal, Business Manager Regulatory Services, Leatherhead Food International

Global regulatory food advice is one of the core areas of expertise at consultancy and research firm Leatherhead Food International. The regulatory advisors work within three teams specialising in United Kingdom, European (EU) or International regimes. Working with not only generic EU controls, but the detail of individual member states…

Quick shelf life prediction: TNO develops unique microbial genomics toolbox

3 December 2008 | By TNO, Food and Biotechnology Innovations

Consumers demand healthy, tasty foods with a fresh appearance and a long shelf life. To meet these expectations, the food industry has to be innovative in product and process optimisation. TNO has developed a unique microbial genomics toolbox that enables food manufacturers to quickly predict shelf life and design new…

Understanding microbial ecology essential for controlling microbial food spoilage

3 December 2008 | By Johanna Björkroth, Professor of Food Hygiene, Helsinki University

As a Professor of Food Hygiene, I have been teaching my students to understand the limitations associated with the determination of total aerobic bacterium levels when used for predicting food shelf life or as quality indicators. It is almost touching to notice how difficult it is to understand that the…

Measurement of water dynamics by low-field NMR

18 August 2008 | By Dr Hanne Christine Bertram. Senior Project Scientist, University of Aarhus

Water is a major constituent in many foods. For example, in several of our basic food items such as muscle-based foods and vegetables, water is the dominating component and is in many ways of primary importance for the quality of these products. Low-field proton NMR relaxometry is an excellent technique…

Mapping food composition using NIR hyperspectral imaging

18 August 2008 | By S.J. Millar, M.B. Whitworth, A. Chau, Campden & Chorleywood Food Research Association and J.R. Gilchrist, Gilden Photonics Ltd

Near infrared (NIR) spectroscopy is widely used in the global agri-food industry for the non-destructive assessment of both the compositional and physical characteristics of a wide range of raw materials and finished products. This is particularly so in the cereals and related industries where, following the commercial development of suitable…

A perspective on actual technologies and future developments

18 August 2008 | By Giuseppe Mensitieri, University of Naples Federico II and Giovanna Giuliana Buonocore, Institute for Composite and Biomedical Materials – National Research Council

In this contribution, the topic of Modified Atmosphere Packaging (MAP) is reviewed by describing the actual status of this technology and its possible developments, which are mainly related to the combination of MAP with other preservation technologies. Among them, particular attention is devoted to active packaging with antimicrobial properties.

The risks of psychrotrophic Clostridium botulinum in MAP and vacuum packed chilled foods

18 August 2008 | By Greg Jones, Senior Research Officer for the Preservation, Processing and Spoilage Group, Campden & Chorleywood Food Research Association

Foodborne botulism is a severe illness that is caused by the consumption of foods containing a neurotoxin produced by a bacterium called Clostridium botulinum. Very little of this toxin is required to cause illness; for example, in 2002, a 35 year old man put a piece of baked potato in…

A new generation of natural and nutritious pleasure-foods

18 August 2008 | By Joy Wilkinson, Mark Berry, Peter McClure and Susie Turan, Unilever Plc

Key driving forces for new foods are naturalness and nutrition. Consumers also expect pleasurable eating experiences. Unilever have recently launched “Frusi” , a completely new concept in ice cream that addresses the ‘enjoyment versus health’ paradox – the idea that something that tastes good cannot be healthy and vice versa.…

An introduction to food safety and HACCP law

18 August 2008 | By Carol Wallace, Principal Lecturer, University of Central Lancashire and Sue Powell, Co-ordinator for the North West Teaching Public Health Network

All businesses need to make sure that they operate within the law for a wide range of measures, including health & safety, environmental issues, weights and measures, et cetera. For food businesses, it is crucial that the food sold does not endanger public health, therefore adequate control systems must be…
