The Application of PE/Thermochromic Composite Film to Sliced Fresh Pork Tenderloin

Abstract:

PE/thermochromic composite membrane is a kind of new functional materials which is composited by PE and thermochromic membrane.PE/thermochromic composite films retain the thermochromic membrane performance of changing the color by absorbing the heat. The composite film cannot be dissolved by water because of the structure which PE film is attached to the both sides of thermochromic film.The effect of the composite film and Nylon/low density polyethylene (LDPE) film on quality of fresh pork meat stored were investigated respectively. The treated meat samples were analyzed periodically for color difference. The results indicate that preservation effect of both films has no significant difference when the fresh pork are stored at 3-5°C, but PE/thermochromic composite films has better preservation effect at 30°C in compared to the Nylon/ LDPE. filmsfilms
