Technological Prospection and Development of Smart Film with Phytochemical Actives such Curcuma longa L.
Abstract
Biodegradable plastics are in evidence regarding packaging, especially for food. Innovative products have their stages better targeted when understanding what has been protected by patents and identifying unexplored trends. This work makes technological prospection and does a film based on PVA added with a dry extract of Curcuma longa, evaluating its function as a barrier to light transmission in five concentrations. The results showed that films with different colorings were rigid and slightly malleable. As a barrier to light transmission, the product proved efficient as the concentration of Curcuma longa L. increased. The films have been presented as an excellent option for the light barrier; improvements are necessary regarding the solubility of the active in the filmogenic solution.
