For further information on Blackwell Publishing, visit our website: www.blackwellpublishing.com Preface The food industry reacted for many years to consumer demand for more appealing and convenient food products by using additives. More recently, the demands of consumers have grown to include still higher performance products but with less additives. The industry has responded accordingly. There are often significant scientific and technical obstacles to be overcome to make a product with less additives. It is these technical challenges that are addressed in this book. The approach taken in this book is to examine specific aspects of the industry where important contributions are being made to avoid or reduce the use of additives or to create new, natural and more acceptable additives which can replace the old ones. There is a tremendous amount of work underway in this field and to cover it comprehensively would fill many volumes. This volume addresses the areas where there has been a considerable amount of recent activity and published results. Chapter 1 was contributed by Keith Anderson of the London Metropolitan University and Principal Consultant with Ventress Technical Services Ltd of Surrey, England. This includes mechanical upgrading of underutilised carcass meat, meat surimi, upgrading of meats using fractionation techniques, ingredients from blood, egg and other products and potential techniques for the production of animal-derived ingredients. Chapter 2 addresses new marine-derived ingredients and was contributed by Torger Børresen, Research Director of the Danish Institute for Fisheries Research. The characteristics of marine foods and specific marine-derived compounds are addressed. In Chapter 3, Terry Sharp, Head of the Baking & Cereals Processing Department of Campden and Chorleywood Food Research Association, England covers reduced-additive breadmaking technology. The major areas of development covered in this area are com- pensating for raw material variation, improvement of dough-handling characteristics and extending the shelf-life of bread. Novel food packaging is reviewed in Chapter 4 by Kit Yam, Associate Professor of Food Packaging and Engineering at Rutgers University, New Jersey, USA and Michael Rooney, Principal Research Scientist with CSIRO Food Research Laboratory in Australia. The scope for avoidance of additives is covered as are properties of packaging materials, packaging processes, active packaging technologies and future opportunities. Chapter 5 on antimicrobial preservative-reduced foods by Nicky Beales of Campden and Chorleywood Food Research Association, England and the editor, Jim Smith of the Food Technology Centre in Prince Edward Island, Canada, addresses the control of micro- organisms in foods and various strategies for producing preservative-reduced or preservative- free foods. This includes evaluating the processing environment, processing methods and alternative natural food preservation systems as well as combinations of existing preservative mechanisms and natural preservatives. Nazmul Haq, Director of the International Centre for Underutilised Crops at the University of Southampton in England, has reviewed new plant-derived ingredients in Chapter 6. A wide variety of ingredient plants and food plants has been identified. These plants will vi PREFACE be invaluable over the years ahead as resources in their own right and as genetic sources for new varieties. Chapter 7 by Creina Stockley of The Australian Wine Research Institute, Terry Lee (formerly of The Australian Wine Research Institute and now with E&J Gallo Winery, Modesto, CA, USA) and Nigel Sneyd (formerly of The Australian Wine Research Institute) reviews reduced additive brewing and winemaking. Antimicrobial agents and antioxidant agents are the two main concerns facing the industry and these are covered with particular emphasis on reducing the use of sulphur dioxide. Food from supplement-fed animals is reviewed in Chapter 8 by Cameron Faustman of the Department of Animal Sciences at the University of Connecticut, USA. The use of feed supplements is a growing area of research for improvement of the quality of meat. Supplementation with Vitamin E, carotenoids and Vitamin C is addressed. Cholesterol reduction, alteration of fatty acid profiles and competitive exclusion are also covered. Chapter 9 covers starter cultures in dairy products, meat products and bread. The author is Gunnar Mogensen, Principal Consultant with GM-Consult, Denmark and former Director of Research and Development for Chr. Hansen’s Laboratorium. He examines develop- ments in starter culture technology and illustrates various ways in which starter cultures are replacing traditional additives in foods. Contributors Professor Keith G.

Description:
Since some food additives have been shown to be harmful to certain individuals, a common perception now is that all food additives are potentially dangerous. This had led to a large market for products making minimal use of additives. Tight regulatory control and labelling requirements provide furth
