Περιγραφή
Fats in Food Technology, 2nd Edition
This is a book about the roles and behaviours of fats in food technology and the benefits that they impart to consumers. It is about fats that are naturally present in foods (e.g. milk fat in cheese) or fats that have been added to improve physical and chemical properties (e.g. cocoa butter in chocolate). Now in a revised and updated second edition, 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 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 relevant chapters. This volume will be useful to anyone in industry and research establishments who has an interest in the technology of fat-containing food products, eg scientists in the dairy, bakery, confectionery and wider food industries as well those involved in the production of edible oils.
