Outline of Final Research Achievements |
The overall purpose of this research is to enhance the storage stability of lotus root. In order to achieve this goal, in the first year of the project, on one hand we focused on the development of composite films consisting of different combinations of chitosan and nanoclay as a primary step to produce films with enhanced mechanical properties and selective gas barrier, foreseeing their application as packaging material for lotus root, and possibly reduce the browning upon storage. We also looked into the development and characterization of Oil-in-Water nanoemulsions loaded with natural antimicrobial and antioxidant compounds, for optimum antimicrobial and antioxidant activities. The experimental results indicated that the O/W nanoemulsions loaded with both, nisin and carvacrol, having droplet mean diameter of around 120 nm, were considerably stable under the conditions investigated (up to 1 week storage at room temperature).
