AB  - A high density polyethylene (HDPE)/calcium carbonate (CaCO(3)) film containing 
      TiO(2) was prepared via blown film extrusion process. The photocatalytic 
      properties of this film were evaluated by voltammetric, UV-Vis spectrophotometric 
      and gas chromatographic measurements following the decomposition rate of suitably 
      selected molecular probes, such as 4-hydroxybenzoic acid and methylene blue. The 
      film containing 1% w/w of TiO(2) displayed a profitable and reproducible 
      photoinduced degradation activity towards target organic compounds. The effect of 
      packaging photocatalytic activity on the structural and microbiological stability 
      of a short-ripened cheese was studied. Cheese structure was assessed by dynamic, 
      small deformation rheological tests. A container consisting of a multilayer 
      material, where the layer brought in contact with the food, made from the 
      HDPE+CaCO(3)+TiO(2) composite matrix, was able to provide a greater maintenance 
      of the original cheese structure than a rigid container currently used, mainly 
      due to the inhibition of lactic acid bacteria and coliforms.
