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 of fruit-containing non-carbonated bever ages is the highly successful marketing of ready-to-drink products.
In the Seventeenth Symposium on Biotechnology for Fuels and Chemicals, leading researchers from academia, industry, and government present state-of-the-art papers on how bioengineering can be used to produce fuels and chemicals competitively. This year's program covered topics in thermal, chemical, and biological processing; applied biological processing; bioprocessing research; process economics and commercialization; and environmental biotechnology. The ideas and techniques described will play an important role in developing new biological processes for producing fuels and chemicals on a large scale, and in reducing pollution, waste disposal problems, and the potential for global climate change.
