Abstrakty

W pracy zaprezentowano sposób otrzymywania pochłaniacza tlenu w formie żelaza wbudowanego w matrycę silikonową. Dodatkowo przedstawiono ocenę skuteczności otrzymanych pochłaniaczy w zakresie ochrony produktów spożywczych na przykładzie podatnych na utlenianie orzeszków ziemnych. W tym celu oznaczono liczbę kwasową i nadtlenkową tłuszczów wyizolowanych z orzeszków przechowywanych w opakowaniach zawierających pochłaniacz tlenu oraz, dla porównania, orzeszków przechowywanych w opakowaniach bez pochłaniacza tlenu.

Commercial oxygen scavengers based mainly on iron compounds are used as sachets, pellets, sheets and film materials. This paper focuses on a new type of oxygen scavengers, in which the oxygen absorbing substance, i.e. metallic iron, is embedded in the silicone polymer. The silicone polymer matrix was chosen due to its high oxygen permeability as well as in order to effectively prevent any direct contact of iron with the packed product. The protective properties of the obtained oxygen scavenger were tested using roasted peanuts as an experimental material. The changes of the oxygen concentration in the packaging as well as the changes of the acid value and peroxide value of the fats present in the peanuts were measured during peanuts storage. The study shows full usefulness of the obtained silicone encased iron composite as food protective oxygen absorbent. (original abstract)
