Improving food safety of sprouts and cold-smoked salmon by physical and biological preservation methods

Abstract (English)

The safety of raw, ready-to-eat foods is of paramount importance and is in the focus of the food industry, consumers as well as food scientists. To improve the food safety status of the products, efficient decontamination as an important processing step and/or the use of protective microorganisms as biocontrol agents are promising approaches. In our work we successfully used these approaches for raw sprouts and cold-smoked salmon as examples for RTE foods. Therefore the set goals have been successfully performed and essential scientific knowledge has been contributed. The results have been published and are described in the following in form of the respective abstracts.

Abstract (German)

Die Lebensmittelmittelsicherheit von rohen, verzehrsfertigen Lebensmitteln ist von überragender Bedeutung was Lebensmittelherstellern, Verbrauchern sowie Lebensmittelwissenschaftlern bewusst ist. Um den Status der Lebensmittelsicherheit zu verbessern, ist die Dekontamination durch Waschen mit heissem Wasser ein wichtiger Prozessschritt; hinzu kann der Einsatz von Schutzkulturen als biologisch wirksames Agends vielversprechendes Verfahren kommen. In unserer Arbeit haben wir diese Strategien erfolgreich bei roh zu verzehrenden Keimlingen und Räucherlachs angewandt. Somit wurden die gesetzten Ziele erfolgreich ausgeführt und wesentliche wissenschaftliche Erkenntnisse beigetragen. Die Ergebnisse sind publiziert und werden nachfolgend in Form der veröffentlichten Zusammenfassungen beschrieben.
