In combination with a base, gallic acid is a potent oxygen scavenger with a very high oxygen absorption capacity. One gram of gallic acid absorbs 450 mg of oxygen &#8211; more than the capacity of the iron powder that is currently used.<\/p>\n<p>The absorption reaction is activated by the humidity of the food. A multilayer packaging film was produced in a pilot-scale three-step process involving compounding, cast film extrusion, and lamination. The film comprised a food contact layer (Bio PE), an active layer containing the scavenger (Bio PE + 15% (w\/w) OSc), a biobased adhesive, and an outer barrier layer (PLA) that reduced O<sub>2<\/sub> ingress from the environment.<\/p>\n<p>The film could be thermoformed to produce trays suitable for thermo-sealing. Interestingly, gallic acid was found to be able to withstand the extrusion process. The film reacts with oxygen at a relative humidity &gt; 75 % and is therefore suitable for food products with a high-water activity, which need to be protected from headspace oxygen or oxygen permeation. By using gallic acid, active packaging materials fully made of sustainable materials can be achieved.<\/p>\n<p>The results of the study can be found here:<br \/>\n<a href=\"http:\/\/www.mdpi.com\/1996-1944\/10\/5\/489\/pdf\" target=\"_blank\">http:\/\/www.mdpi.com\/1996-1944\/10\/5\/489\/pdf<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Working in collaboration with the Technische Universit\u00e4t M\u00fcnchen (TUM), Fraunhofer Institute for Process Engineering and Packaging IVV has developed a multilayer packaging film containing a new fully biodegradable, plant-derived oxygen scavenger: gallic acid.
