[...]... since the first edition of this textbook, significant advances have been made in our understanding of physical chemistry of foods, and in particular of the effects of environmental factors on rates of changes in foods These advances in knowledge have led to refinements in formulation of principles of food preservation and in the development and application of new processes for preservation of foods As predicted... different from the first edition, except for constancy in purpose and in most of the topics covered It is an honor and genuine pleasure to introduce the reader to this fine second edition of Physical Principles of Food Preservation I believe you will find it of great value Owen Fennema Department of Food Science University of Wisconsin – Madison Madison, Wisconsin, U.S.A Preface to the Second Edition In the 28... professions using food science, such as government and industry professionals Marcus Karel Daryl B Lund Preface to the First Edition The subject of food processing occupies a position of major importance in the food science curriculum, and this emphasis is likely to continue Thus it is both puzzling and reprehensible that a university-level textbook tailored to the needs of typical students in food science. .. of Food in Chilled Atmospheres of Modified Composition D Handling of Food Following Removal from Chilling Storage References 237 237 238 Freezing I Introduction A Objectives of Freezing of Foods B Size of the Food Industry II Physicochemical Principles of the Freezing Process A Introduction B Water and Ice C Nucleation in Pure Water D Freezing Point Depression in Solutions, Biological Systems, and Foods...
