In response to this need, we have decided to change the title of the book to Quality Control for the Food Industry, and to bind it in two volumes. The first volume remains largely the same as before except for updating and omission of some material which by no stretch of the imagina¬ tion can be considered fundamental. Thus, Chapter 10 on Micro- analytical Methods has been rewritten to include Microbiological Methods. The former Chapter 11 on Water, Waste Control, and Sanitation has been deleted from Volume 1 and now appears in ex¬ panded form in Volume 2 on Applications. Instead, we have in¬ serted a complete new Chapter 11 on Chromatographic Methods. The new material in Chapter 10 has been provided largely by Dr. John G. Kaffezakis, National Can Corporation, and the new Chapter 11 by Drs. William H. Stahl and William G. Galetto, McCormick & Company, Inc. During the last few years there has been a steady and increasing volume of material published on the classifications of quality attri¬ butes, or “parameters,” and attempts made to measure such quality attributes of food strictly in physical terms without reference to the buyer or consumer response. We therefore found it necessary to revise and elaborate Chapter 2 to include some of the new valid findings as well as to attempt to reduce the confusion created largely by the use of different terms or different classifications of the same concepts, or by the introduction of concepts which are not funda¬ mentally sound. Having made these changes in Volume 1, we were then able to put together a second volume specifically on applications. In addition to the material transferred from Volume 1, Volume 2 is organized mainly on the basis of commodities. Amihud Kramer Bernard A. Twigg Jan. 20, 1970 V VI QUALITY CONTROL FOR THE FOOD INDUSTRY Preface to the Second Edition In this revised edition corrections and additions have been made to practically every chapter to up-date the material so as to include new relevant findings developed during the last five years. With the tremendous research output in flavor measurement in recent years, it is now possible to devote a more complete chapter to this subject. The chapter on flavor still remains relatively moder¬ ate in size, however, because even now the objective measurement of flavor by techniques that would be applicable to quality control are still few, with major emphasis remaining in sensory evaluation as performed by taste panels. A brand new chapter on Evolutionary Operation has been added, since this procedure has come into its own as a quality control tech¬ nique only within a few years. Amihud Kramer Bernard A. Twigg July 1,1966
