Publication number: 20240093043Abstract: The present invention relates to a kit for improving food shelf life comprising a sheet-like element component and an alkaline component. The sheet-like element component comprises a particulate filler comprising surface-reacted calcium carbonate, a binder and an oxygen scavenger. The oxygen scavenger is a compound comprising at least two phenolic hydroxyl groups, which can be deprotonated by the alkaline component, thus activating the oxygen scavenger. Further aspects of the present invention relate to an activated sheet-like element formed from the inventive kit, a process for the manufacture of a kit for improving shelf life, a process for the manufacture of a sheet-like element component, a process for activating the sheet-like element component, a supply device comprising the activated sheet-like element, a food packaging comprising the activated sheet-like element and the use of the kit or the activated sheet-like element in a food packaging and for prolonging food shelf life.Type: ApplicationFiled: January 21, 2022Publication date: March 21, 2024Applicant: Omya International AGInventors: Fabien Wilhelm MONNARD, Bettina RÖCKER, Stefanie WALLER, Jan Philipp WEIHS, Selcuk YILDIRIM, Rico MÉNARD
