Development of Active Films with Collagen Fiber and Polyvinyl Alcohol Mixture and Incorporation of Oregano and Rosemary Essential Oils in Their Matrix

The aim was to develop films with a new mixture of collagen fiber plus polyvinyl alcohol added oregano or rosemary essential oils at different levels (0%, 2%, 4% and 6%), as well assess the antimicrobial activity, physical, optical, microstructure molecular properties in films. An interaction between ingredients observed level by FTIR. amide II III bands, which are important verify conformation, showed intense peaks formation network through fibers produced, acting reinforcement matrix. oil had an expressive activity steam contact method (micro-atmosphere), mainly for Escherichia coli Staphylococcus aureus. is promising matrix application food active packaging.
