This new edition of a highly successful book retains the emphasis on the practical approach to rancidity in foods which was the hallmark of the previous editions. There has been substantial revision to bring existing chapters up-to-date with current techniques and the inclusion of additional chapters on spectrophotometric and chromatographic analysis of oxidation, legislative and labeling aspects, and HACCP in the avoidance of rancidity. There are also new chapters on rancidity in fish and in confectionery products.

This is the second volume in a series which presents the state of the art in chosen sectors of oil and fat chemistry, including its relevance to the food and pharmaceutical industries. The text in this book aims to provide an authoritative account of the use of a wide range of spectroscopic methods in the analysis of lipids, with an emphasis on topics that have attracted special attention.

This book has been written to ensure that it will be of benefit to industrial analysts. Most chapters explain some of the relevant theory as well as give some historical references to place the technique in its proper context. In addition the book should appeal to academic scientists who require a good source of applications and a good set of references. Since lipids have many uses the appeal of the book will extend from the food industry to the pharmaceutical industry. R.

This first volume in a series is intended to provide up-to-date information on specific topics in oils and fats. The book will be especially valuable for any practising scientist or technologist who deals in any way with oils and fats whether from a nutritional, surfactant, cosmetic or analytical chemistry point of view. In addition there is sufficient depth in most of the articles to catch the imagination of many more senior managers in the industry. The oils and fats industry is closely aligned with the food industry and it is no surprise to find that five of the chapters (1, 2, 3, 6 and 7) are written from a food perspective. The current arguments about diets and their fat content are well developed in Dr Enser's chapter on meat lipids. He has presented a very balanced picture explaining that there are many reports which contradict the fashionable 'saturated fatty acids are bad' theory. This chapter will do much to illustrate the dietary implications of meat lipids and should stimulate discussion and further research.

Since we produced Fats and Oils: Chemistry and Technology in 1980, the trend we anticipated to up-date the classical texts of oils and fats has manifested itself. Bailey's famous textbook has been completely revised and a second edition of Bernardini's work has been produced. The present text is an attempt to provide some insight into the current state of the art. Chapter 1 discusses the physical properties of oils and fats with special reference to those properties which can be monitored to give an in dication of the suitability of fats for chocolate production. The physical properties of the fats are often determined by the order in which the fatty acids are attached to the glyceride molecule. Ram Bhati, in the last article he wrote before his death, showed how mass spectrometry and chemical methods could be used to determine the sequence of fatty acids. Ram's essentially practical approach to the problem is exemplified by the section dealing with the experimental details of the techniques. Chapter 3 outlines some of the problems which can arise in industry when the lipid part of a foodstuff undergoes oxidation, whilst in Chapter 4 Patterson describes the major technique, hydrogenation, which is used to circumvent the problems caused by oxidation of the unsaturated fatty acids. In Chapter 4 the essentials of the theory are given to enable the reader to appreciate the design features of the apparatus. Chapter 5 deals with the analysis, mainly chromatographic, of lipids."
