Abstract
Mit Hilfe hydrostatischen Hochdrucks pasteurisierte Lebensmittel werden in Japan bereits vermarktet. Auch in Europa und USA ist das Interesse an dieser Methode groß. Temperatur und Druck sind die wichtigsten Parameter, die den Zustand der Materie -auch von Lebensmitteln — beeinflussen. Während die Einwirkung von Temperatur auf Lebensmittel seit langem Gegenstand von Untersuchungen ist, ist der Einfluß des Druckes auch in Kombination mit Temperatur auf Lebensmittel ein relativ junges Forschungsgebiet. Generell sollten Vorgänge und Reaktionen in Lebensmitteln untersucht werden, die dem Prinzip von Le Chatelier unterliegen. Hierzu gehören chemische Reaktionen niedermolekularer und makromolekularer Verbindungen. Es werden theoretische Grundlagen und Beispiele für durch Druck beeinflußte Reaktionen vorgestellt. Food pasteurized by hydrostatic high pressure have already been marketed in Japan. There is great interest in this method also in Europe and USA. Temperature and pressure are the essential parameters influencing the state of substances including foods. While the influence of temperature on food has been extensively investigated, effects of pressure, also in combination with temperature, are attracting increasing scientific attention now. Processes and reactions in food governed by Le Chatelier's principle are of special interest; they include chemical reactions of both low- and macromolecular compounds. Theoretical fundamentals and examples of pressure affected reactions are presented.Keywords
