Alternative green food processing technologies have gained much technical and industrial attention in recent years as a potential means of reducing costs and promoting consumer awareness of corporate environmental responsibility. However, utilizing green principles is now becoming an effective business approach to enhance vegetable oil processing profitability. Two years have passed since the first edition of Green Vegetable Oil Processing was published. The Revised First Edition includes much of the content of the first edition, but incorporates updated data, details, images, figures, and captions. This book addresses alternative green technologies at various stages of oilseed and vegetable oil processing. This includes oil extraction technologies such as expeller, aqueous and supercritical methods, and green modifications of conventional unit operations such as degumming, refining, bleaching, hydrogenation, winterizing/dewaxing, fractionation, and deodorization. While most chapters describe soy oil processing, the techniques described equally applicable to oils and fats in general.

Traditional thermal and freezing processing techniques have been effective in maintaining a safe high quality food supply. However, increasing energy costs and the desire to purchase environmentally responsible products have been a stimulus for the development of alternative technologies. Furthermore, some products can undergo quality loss at high temperatures or freezing, which can be avoided by many alternative processing methods. This second edition of Alternatives to Conventional Food Processing provides a review of the current major technologies that reduce energy cost and reduce environmental impact while maintaining food safety and quality. New technologies have been added and relevant legal issues have been updated. Each major technology available to the food industry is discussed by leading international experts who outline the main principles and applications of each. The degree to which they are already in commercial use and developments needed to extend their use further are addressed. This updated reference will be of interest to academic and industrial scientists and engineers across disciplines in the global food industry and in research, and to those needing information in greener or more sustainable technologies.

This multi-authored book is edited by an expert in the field and includes chapters from international contributors. It is fully cross disciplinary relating green principles to the food industry, covering legal and policy issues, engineering, food processing and food science. It addresses the alternatives to conventional food processing that have reduced energy requirements or solvent use and how they affect final food quality. Initially, the principles of green chemistry and technologies are outlined to provide a justification and basis for the processing methods that are addressed. This is followed by a discussion of legal and policy issues in both the EU and the US which provide further justification for the need for such technologies and the constraints and benefits of current policies and regulations. The major green technologies available to the food industry are discussed, outlining the main principles and applications of each. The degree to which they are already in commercial use and developments needed to extend their use further are also covered.
