Extension of shelf life of two fatty foods using a new antioxidant multilayer packaging containing green tea extract

This paper describes the performance of a new antioxidant multilayer packaging material, tested for 16 months with real food and in industrial conditions, as the format, size and material were produced at an industrial level, as a new prototype, following the indications from previous research. In this material green tea extract has been grafted in the internal layer of a multilayer material, in which it acts as a radical scavenger, which means as an antioxidant. The antioxidant behavior of the polymer as well as the performance of the polymer versus real food is described. It is the first time that such a material is successfully produced at the industrial level and in fact, the material is nowadays in the market. For all these reasons the paper is of great industrial relevance. Many industries are and will be interested in it.
