The text also describes the refining process; the fat-modification processes; and the production of edible-fat products of high fat content. The technologies applied to speciality fats; the storage and transport of oils and fats; and energy demands of the oil-milling and edible-fat processing operations. People involved in the processing of edible oils and fats will find the book useful.

The Chemistry and Technology of Edible Oils and Fats contains the proceedings of a conference arranged by Unilever Limited and held at Port Sunlight in England on March 10-12, 1959. The papers explore the chemistry and technology of edible oils and fats, with emphasis on analytical procedures, the methods of industrial processing, and the pattern of dietary fat consumption seen from the viewpoint of the economist. This book is comprised of seven chapters and opens with a discussion on the physical and chemical properties of the constituents of edible oils and fats, with particular reference to the fatty acids, the glycerides, and those closely related compounds which are fatty in a general sense. The following chapters focus on the pattern of fatty food consumption in the United Kingdom; the methods used for the analysis of oils and fats; processing of oils and fats for edible purposes; the use of the isotopic dilution technique in the determination of linoleic acid; and the application of gas/liquid chromatography to the analysis of atheromatous plaques. The final chapter deals with the use of spectroscopic and X-ray techniques in the analysis of oils and fats. This monograph will be a useful resource for chemists and food technologists.

The purpose of the book is to provide its readers a comprehensive background and information about developments in the areas of fat science and fat technology. The book tries to provide information pertaining to both basic and technological aspects and to embrace new technology, like biotechnology, that the enormous commercial importance and potential in the 21st century. The book will help better understanding of extraction technology and would be useful to students & other readers involved in the area of refining.

Until recently fats and oils have been in surplus, and considered a relatively low value byproduct. Only recently have energy uses of fats and oils begun to be economically viable. Food value of fats and oils is still far above the energy value of fats and oils. Industrial and technical value of fats and oils is still above the energy value of fats and oils. Animal feeds value of fats and oils tends to remain below the energy value of fats and oils. With development of new technology oils and fats industry has undergone a number of changes and challenges that have prompted the development of new technologies, and processing techniques. Oils and fats constitute one of the major classes of food products. In fact oils and fats are almost omnipresent in food processing – whether naturally occurring in foods or added as ingredients for functional benefits and, despite the impression given by several sources to the contrary; they remain an essential part of the human diet. However, it is increasingly apparent that both the quantity and the quality of the fat consumed are vital to achieve a balanced diet. They are essential constituents of all forms of plant and animal life. Oils and fats occur naturally in many of our foods, such as dairy products, meats, poultry, and vegetable oil seeds. India is the biggest supplier of greater variety of vegetable oil and still the resources are abundant. The applications of oils are also seen in paints, varnishes and related products. Since the use of oils and fats in our daily life is very noticeable the market demands of these products are splendid. Special efforts has been made to include all the valuable information about the oils, fats and its derivatives which integrates all aspects of food oils and fats from chemistry to food processing to nutrition. The book includes sources, utilization and classification of oil and fats followed by the next chapter that contain details in physical properties of fat and fatty acids. Exquisite reactions of fat and fatty acids are also included in the later chapter. It also focuses majorly in fractionation of fat and fatty acids, solidification, homogenization and emulsification, extraction of fats and oils from the various sources, detail application in paints, varnishes, and related products is also included. It also provides accessible, concentrated information on the composition, properties, and uses of the oils derived as the major product followed by modifications of these oils that are commercially available by means of refining, bleaching and deodorization unit with detailed manufacturing process, flow diagram and other related information of important oils, fats and their derivatives. Special content on machinery equipment photographs along with supplier details has also been included. We hope that this book turns out to be considerate to all the entrepreneurs, technocrats, food technologists and others linked with this industry.

Fats are present in some form in the vast majority of processed foods we consume, as well as in many ‘natural’ products. Changes in consumer behaviour, centered around an increased emphasis on healthy food consumption, mean that it is more important than ever for food scientists to understand the properties, roles and behaviours that fats play in food and in diets. Fats in Food Technology, Second Edition is an in-depth examination of the roles and behaviours of fats in food technology and the benefits that they impart to consumers. It considers both fats that are naturally present in foods (such as milk fat in cheese) and fats that have been added to improve physical, chemical and organoleptic properties (like cocoa butter in chocolate). Newly revised and updated, the book contains useful information on the market issues that have driven change and the disciplines that have helped to regulate the trade and use of fats and oils in food technology. Drawing on the recent literature as well as the personal R&D experiences of the authors, the book highlights those areas where potential efficiencies in processing and economy in the cost of raw materials can be made. Issues concerning health, diet and lifestyle are covered in dedicated chapters. This book will be useful to anyone in industry and research establishments who has an interest in the technology of fat-containing food products, including scientists in the dairy, spreads, bakery, confectionery and wider food industries, as well those involved in the production of edible oils.

The three major macronutrients are proteins, carbohydrates, andlipids (oils and fats). This book is devoted to lipids, which arean important part of life for all of us. What are these materialsin molecular terms? Where do they come from? What happens to thembetween the harvesting of crops and the appearance of the oils andfats in different products in the supermarket? How does natureproduce these molecules and can we act on nature to modify thematerials to increase their beneficial properties? How importantare the minor products present in the fats that we consume? Sinceoils and fats vary, how can we analyse them? What are theirphysical, chemical and nutritional properties? How do the fats thatwe consume affect our health and well-being in both quantitativeand qualitative terms? What are their major food and non-fooduses? This book provides a broad source of reference on oils and fatschemistry for graduates entering the food and oleochemicalindustries, postgraduate researchers and nutritionists. It offers apoint of entry to the detailed literature.
