Inhaltsangabe

The term magnetic resonance covers a wide range of techniques, spectroscopy, relaxation and imaging. In turn, these areas are evolving and leading to various new applications of NMR and ESR in food science and nutrition. This book is part of the continuing series of proceedings of the biennial conferences on applications of magnetic resonance to food science. As always, the aim of the book is to bring the reader up-to-date with the state-of-the-art of the subject. The speakers came from Europe, North and South America, Asia and Australasia giving a global perspective to the event. The range of the conference was broad covering sensory science, authenticity, functionality, solid state methods and new methods. Magnetic Resonance in Food Science is a global survey written by leading authorities. It provides readers with an awareness of current activity in the field and potential applications.

CHAPTER 1

HIGH RESOLUTION NMR ANALYSIS OF COMPLEX MIXTURES

1 INTRODUCTION

Advances in analytical techniques and reduced computation times have facilitated broad ranging characterisation of complex chemical and biochemical systems. Resolution and sensitivity enhancements have ensured a key role for high-resolution liquid state nuclear magnetic resonance (NMR) spectroscopy for the determination of compositional variation in complex matrices including foods. A range of studies utilising NMR spectroscopy and advanced data exploration techniques have illustrated the applicability of these techniques to issues facing the food and agricultural sectors.

In the era of the discerning consumer, attitudes toward food choice have changed markedly from the need to provide basic nutrition to the desire to make informed choices relating to food intake. Consumer choices in relation to food intake are often made on the basis of the perceived health benefits that food borne components may impart, where scientific methods to substantiate these claims are often lacking. Whilst the organoleptic properties of food are doubtless a major factor for continued food consumption, it is also clear that initial choices are often made on the basis of promotional labelling. Information that is present on food labels acts as a comparative index by which initial consumer choices are made. For example, regional produce may be associated with a distinctive flavour. Similarly, production processes including organic, com-fed or free range are associated with superior quality produce or morality probing implications.

Informed consumer preferences are thus leading to a greater range of choices and a concurrent increase in the number of claims that are made by food producers, manufacturers and the broadcast media. These choices can only be considered as informed when public awareness of current scientific knowledge is prevalent. In the scientific communities an extensive phase of evidence gathering is being undertaken in relation to food composition. This is largely being driven by a desire to fully understand the composition of food and its implications with respect to consumer choice and public health. Large bodies of data are being collected and interpreted against specific claims relating to food authenticity, quality, safety and nutrition.

An insight is provided here into the current state-of-the-art for the compositional analysis of molecules in food utilising high-resolution NMR spectroscopy in conjunction with multivariate data analysis techniques. The recent Human Metabolome Project (http://www.metabolomics.ca) has identified 2,500 metabolites, 1,200 drugs, and 3,500 food...
