Soft drinks and fruit juices are produced in almost every country in the world and their availability is remarkable. From the largest cities to some of the remotest villages, soft drinks are available in a variety of flavours and packaging. Over the last decade, soft drinks and fruit juices have been the subject of criticism by the health community and there is considerable pressure on beverage manufacturers to reduce, or even remove, the sugar content of these products. Chemistry and Technology of Soft Drinks and Fruit Juices, Third Edition provides an overview of the chemistry and technology of soft drinks and fruit juices, covering ingredients, processing, microbiology, traceability and packaging as well as global market trends. This fully revised edition now includes chapters on topics that have become prominent in the industry since publication of the previous edition namely: water use and treatment, and microbiology technologies. The book is directed at graduates in food science, chemistry or microbiology entering production, quality control, new product development or marketing in the beverage industry or in companies supplying ingredients or packaging materials to the beverage industry.

The need for a further edition of a book is gratifying for contributors and editor alike. When faced with the corresponding challenge to identify what has changed in one sector of a particular industry, however, initial enthusiasm frequently declines. Nowhere is this more evident than in this book on food flavourings, because the industry still remains the tantalising blend of art, science and technology that was alluded to in the first edition. Instrumentation and analytical skills can now identify flavour components down to nanogram and picogram concentrations and yet the skilled flavourist is often still able to defeat this scientific ability. Many parts of the food industry, and in particular the more traditional outlets such as baking and confectionery, use flavours and methods of application that have changed little in fifty years. At the other end of the spectrum, advanced synthetic chemistry methods and computer-controlled natural product processes can give the flavour industry a greater selection of higher quality materials than ever before. The industry itself has, in recent years, undergone many commercial changes, and in the U.K. some manufacturers' names known for a century or more have disappeared to become part of larger corporate entities. Flavours are for the first time controlled, albeit in a small way, by statute based on a European Directive.

In the period of about five years since the first edition of this book appeared, many changes have occurred in the fruit juice and beverage markets. The growth of markets has continued, blunted to some extent, no doubt, by the recession that has featured prominently in the economies of the major consuming nations. But perhaps the most significant area that has affected juices in particular is the issue of authenticity. Commercial scandals of substantial proportions have been seen on both sides of the Atlantic because of fraudulent practice. Major strides have been made in the development of techniques to detect and measure adulterants in the major juices. A contri bution to Chapter 1 describes one of the more important scientific techniques to have been developed as a routine test method to detect the addition of carbohydrates to juices. Another, and perhaps more welcome, development in non-carbonated beverages during the past few years is the rapid growth of sports drinks. Beverages based on glucose syrup have been popular for many years, and in some parts of the world isotonic products have long featured in the sports arena. A combination of benefits is now available from a wide range of preparations formulated and marketed as sports drinks and featuring widely in beverage markets world-wide. A new chapter reviews their formulation and performance characteristics. Another major trend in the area offruit-containing non-carbonated bever ages is the highly successful marketing of ready-to-drink products."

Fruit and fruit products, in all their many varieties and variations, are major world commodities and part of the economic life blood of many countries, particularly in the developing world. The perception of the healthy nature of fruit is a major reason for its increased consumption in the developed world, and many consumers today find a wider selection of fruit varieties, available at all times of the year, than ever before. This volume, however, is not so much concerned with fresh fruit as those principal areas of processing to which it may be subjected. Fruit processing arose as a means of utilising a short-lived product and preserving its essential nutritional qualities as far as possible. A chapter on the nutritional aspects of fruit is included in this work to reflect the importance of this topic to most consumers. After a general introduction, the chapter on fruit storage is the only contribution which deals with a process from which fruit emerges in essentially the same physical condition. Beyond that the book sets out to cover most of the major areas in which fruit may be processed into forms which bear varying semblances to the original raw material.

The flavour industry is now a vital element in the growth and success of the food and beverage industries worldwide. The development of many new products is directly related to the use of an appropriate flavouring - which, among other benefits, has allowed the use of many novel raw materials as food ingredients.
