Over and above quotas
6 November 2012 | By Mike Mitchell, Director of Quality and Corporate Responsibility, Young’s Seafood
The subject of sustainable seafood seems to be continually in the news. In this short article, we look at how today’s seafood brands and processors are rising to the challenge, we discuss why good marine stewardship is important and explore why future growth of the seafood market depends on factors…
Plastic packaging for fish and seafood
6 November 2012 | By Kata Galić, Faculty of Food Technology and Biotechnology, University of Zagreb
In the past few decades, there has been a significant increase in the amount of plastics being used in food packaging applications. This is because plastics bring in enormous advantages, such as thermosealability, flexibility in thermal and mechanical properties, permit integrated processes (i.e. plastic packages can be formed, filled and…
The chemistry of beer
6 November 2012 | By Charles W. Bamforth, Anheuser-Busch Endowed Professor of Malting & Brewing Sciences at UC Davis
It has variously been estimated that there are between 1,000 and 2,000 different chemical species in beer, probably twice as many as are present in wine. It is an extraordinarily complex liquid. Not all of those chemical components make a substantial contribution to the quality of beer, but many do.…
Implementation of removing trans fatty acids originating from PVHO
6 November 2012 | By Sergey Melnikov, Lead Technologist and Oil Processing and Fat Blends Team Leader and Hans Zevenbergen, Nutrition & Health Europe and Cross-Category Nutrition & Health Director, Unilever
Trans fats (also known as trans fatty acids, or TFA) are formed in the digestive system of ruminants. In the food industry, a similar process called ‘partial hydrogenation’ is used to convert vegetable oils into solid fats for enhanced functionality and shelf life stability. The main sources of TFA in…
Benefit risk assessment of microbial food cultures
6 November 2012 | By François Bourdichon, Nestlé Research Centre; Joerg Seifert, International Dairy Federation and Egon Bech Hansen, Technical University of Denmark
Fermentation as a chemical process was initially described in the mid-19th century by Louis Pasteur as ‘a vie sans l’air’, the metabolic process of deriving energy from organic compounds without the involvement of an exogenous oxidising agent. Fermentation, as a process for manufacturing fermented foods, is today used more broadly…
Application of vacuum in the food industry
6 November 2012 | By Frank Moerman, European Hygienic Engineering & Design Group and Nico Desanghere, Sterling Fluid Systems
Vacuum allows processes to be performed that cannot otherwise be done under atmospheric conditions. Moreover, it offers a huge advantage in the processing of heat and oxygen sensitive materials. There are numerous applications in the food industry that rely on vacuum. The vacuum required in the food industry extends in…

Dr. Doris Engesser-Sudlow of DuPont Nutrition & Health looks at how customers can benefit from a complete safety and ingredients portfolio.
Imaging lipids in native specimen with TCS SP8 CARS – CARS at video rate
17 September 2012 | By
Sophisticated food studies rely mainly on chemical techniques which reveal only a few and often isolated aspects of a sample. As the focus of food science concentrates more on a whole system, like dynamics of lipid components or water in various types of food, more detailed information of these structures…
Unravelling chocolate aroma
6 September 2012 | By Angela Ryan and Alison Hemesley, Nestlé Product Technology Centre
It’s been almost 500 years since Aztec Emperor Moctezuma reputedly introduced Hernando Cortéz to his favourite cocoa-based beverage Xocolatl, but our demand for cocoa and more recently chocolate has continued to grow ever since. Today, world cocoa production is estimated to be 3990 million metric tons and the major cocoa…
Packaged chillers with ammonia as a refrigerant: the natural choice
6 September 2012 | By René van Gerwen, Global Lead Engineer Refrigeration & HVAC, Unilever Engineering Services
Industrial chillers for the supply of chilled water, cold glycol or brine, are frequently used over a long time, and have become even more attractive for several applications to replace direct refrigeration systems. Greenhouse gas footprint and lifecycle costs of ownership of industrial chillers can be significantly reduced by using…
Innovative freezing technologies for foods
6 September 2012 | By Stephen J. James & Christian James, Food Refrigeration and Process Engineering Research Centre, Grimsby Institute of Further and Higher Education
Freezing is a well-established food preservation process that produces high quality nutritious foods that offer the advantage of a long storage life. However, freezing is not suitable for all foods and freezing does cause physical and chemical changes in many foods that are perceived as reducing the quality of the…
Practical examples of innovative NMR approaches to food analysis
6 September 2012 | By Luisa Mannina, Dipartimento di Chimica e Tecnologie del Farmaco, Sapienza Università di Roma & Laboratorio di Risonanza Magnetica Annalaura Segre, Istituto di Metodologie Chimiche, CNR and Anatoly P. Sobolev Laboratorio di Risonanza Magnetica Annalaura Segre, Istituto di Metodologie Chimiche, CNR
NMR spectroscopy is currently one of the key methods for food characterisation1. Foodstuff is a complex matrix including many different compounds with different chemical structures, concentrations, solubility, properties and nutritional values. Each food type contains primary and secondary metabolites. Primary metabolites, i.e. organic acids, amino acids and sugars, involved in…
