Water Properties of Food, Pharmaceutical, and Biological Materials is based on lectures and papers presented by leading international researchers of the field at the 9th International Symposium on the Properties of Water in Foods (ISOPOW 2004) held at Mar del Plata, Argentina, from September 25 to 30, 2004.
Food materials, biological and pharmaceutical scientists have recognized that water plays an important role on the structure, functionality and stability of biomaterials. The ubiquitous water molecules are small and simple, but they develop complex interactions and present unusual properties for unprepared observers. We thus aimed to overlap areas of different fields of research having in common problems faced by how and why water behaves as it does. The theme chosen for ISOPOW 9 meeting was "Water properties related to the technology and stability of food, pharmaceutical and biological materials". The understanding of the properties of water in foods, enriched by approaches from polymer and materials sciences, and by the advances of analytical techniques, made us to detect unsolved questions and the need to go deeply into them.
About 90 participants from 19 different countries attended ISOPOW 9, the program of which embraced areas of contemporary interest. In each of the seven sessions, there were three or four oral presentations by invited speakers giving 24 invited lectures. There was wide time provided for discussions. From the 89 submitted abstracts, 74 were accepted, and the members of the Scientific Committee recommended 20 of them to be presented orally.
ISOPOW 9 made it possible also the organization of a workshop on ¨Dynamics and relaxation in supercooled fluids and glassy systems”. This activity was organised with the objective of bringing together postgraduate students and researchers in the area, to generate an environment for discussion of the theoretical and experimental aspects of non-equilibrium processes in supercooled fluids and glasses. The workshop was attended by 20 young researchers and PhD students of different universities and national laboratories of Argentina. Lectures were performed by C.A. Angell (Arizona State University), G. Appignanesi (National South University, Argentina), B. Bagchi (Indian Institute of Science, Bangalore, India.), H. Corti (Comisión Nacional de Energía Atómica, Argentina), J. de Pablo, (University of Wisconsin), P. Debenedetti, (Princeton University), R. Grigera (University of La Plata, Argentina), T. Grigera, (University of La Plata, Argentina) and V. Molinero (California Institute of Technology).
Part 1: Invited Lectures
Roberto Fernández Prini presented “Water: a simple molecule and a fascinating liquid” at the Opening Conference. Dr. Fernández Prini is an Honorary Fellow of The International Association for the Properties of Water and Steam (IAPWS)), and he gave a general picture from an interesting point of view on some features that are yet not satisfactorily explained to understand aqueous systems at ambient temperature: the role of length-scale to explain features of the behaviour of hydrophobic solutes, the need to use theories for inhomogeneous fluids to deal with confined aqueous systems.
Part I of this book (Chapters 1 to 5) is based on presentations from invited speakers.
Chapter 1 covers several basic aspects discussed in Session I, “Dynamics and relaxation in amorphous aqueous systems”, chaired by Dr. Raúl Grigera. This Session served as a start point of the Symposium, before moving to more applied aspects of the following parts.
Several phenomena occurring at different length scales, from macroscopic to molecular dimensions, are covered in Chapter 2, “Role of water in structural and functional properties, from microscopic to macroscopic properties”. These topics were discussed in Sessions II (chaired by Dr. David Reid) and III (chaired by Dr. Anne Marie Hermansson), remarking the usefulness of new tools both for instrumental and computer calculations to solve questions on the behaviour of water in its relation to solutes.
The subject of “Responses to water stress in living organisms. Related new potential technologies” was discussed in Session IV, in which Dr. Yrjö Roos acted as Chairman. The corresponding conferences were included in Chapter 3.
It is interesting to remark that the different contributors of this session covered several aspects of living organisms from innovative viewpoints, on the basis of new experimental and theoretical tools for understanding the response of stressed organisms under extreme conditions.
Special aspects of suspensions and emulsions with especial emphasis on the characteristics of the interfaces were covered in Session V “Water and the structure and stability of microdisperse systems”. Dr. Ana Pilosof was the chairman, and the conferences were included in Chapter 4.
Some of the subjects discussed in Sessions VI (chaired by Dr. Pilar Buera) and Session VII (chaired by Dr. Peter Lillford) were included were included in Chapter 5 of this book, under a general title “Overlapping water relations and material sciences for the improvement of quality products: past, present and future”. Researchers from pharmaceutical and food sciences were gathered to provide a clear picture of recent advances in understanding the preservation of biomolecule functionality in restricted water environments and how to manage the adverse effects of water on sensitive components. In the last Session Dr. Theodore Labuza dedicated a space to the subject “Material science in food technology and pharmaceutics” inspired by Dr. Marcus Karel. Those who were his former students (Theodore Labuza, Jorge Chirife, Yrjo Roos and Pilar Buera) made a combined presentation on that subject.
In this last session it was made evident first, how the main areas of water relations of foods had evolved through the years and second, how several phenomena which could not be explained some years ago can now be interpreted with new tools from polymer and materials sciences.
Part 2: Oral presentations and Posters.
Four special sessions were dedicated to oral presentation and discussion of selected 20 posters. Drs. Jorge Welti-Chanes, Miang Hoong Lim, Norio Murase and Peter Lillford were the chairmen of the oral sessions, which are included in Part 2 of this book. Short papers from posters presentations were also included in Part 2. About these presentations, in his report to the Central Committee, Dr. Lillford pointed out that “Of particular note was the quality of short presentations and posters. The benefit of screening this material by the local organisers was evident, and Central Committee recommends that this practice be adopted in future meetings”.
It was interesting to see how different fields of knowledge (food, pharmaceutical and biological sciences) are affected by common phenomena, and share analytical tools to solve different problems, and how water is the conducing wire among them.
It was made clear in the whole Symposium that Food Science has broadened its spectrum of subjects and points of view, from basic to applied aspects, from macroscopic to microscopic and molecular phenomena. The combination of efforts from several disciplines has also advantageously enriched the knowledge on water and its relationships with food components.
ISOPOW 9 has been made possible through the efforts of a number of individuals and organizations.
The International Union of Food Science and Technology (IUFoST) and two Research organisations, the National Agency of Scientific and Technological Promotion (ANPCYT) and National Research Council (CONICET) from Argentina co-sponsored the meeting. The participation of several Ph.D. students and young researchers was made possible by financial support provided by Fundación Antorchas. ISOPOW 9 also received financial support from Decagon Devices, Mettler-Toledo, Bruker, and the local Universidad Católica Argentina, D’Amico Sistemas, Microanalítica and Tec Instrumental. The organising Committee acknowledges the auspices of Universidad de Buenos Aires, Universidad Nacional de Luján and Municipalidad de General Pueyrredón.
The Symposium Programme was prepared by the members of Central and Local Committees. The Editors wish to recognise members of all ISOPOW 9 Comitttees and Session Chairmen for their considerable efforts in the evaluation of papers and for their help in the organisation. All local arrangements were the responsibility of the Local Committee.
