Biodegradable eco-films based on organic raw materials with active components

To date, the problems of food losses of food products are relevant. The development of active films and coatings based on them opens up new opportunities for prolonging the shelf life for food, as well as solving global problems associated with the uncontrolled growth of polymer waste. Scientists around the world are developing innovative approaches to obtaining film material based on organic raw materials. Polysaccharides (starch, pectin, etc.) are used as the basis for the formation of the matrix. Scientists suggest using chitosan, curcumin, zinc oxide, essential oils, etc. as an active ingredient with an antimicrobial effect. The ingredients can be used both in their pure form and their modification. The aim of this study was to study the effect of the Pickering emulsion stabilized by zinc oxide nanoparticles at different concentrations (0.5 and 1.0 %) on the functional properties of the biodegradable active film. As part of the study, 3 samples of the active film were prepared. During the study, film samples were evaluated for such indicators as thickness, water content, solubility in water, opacity and antioxidant activity. As a result of processing experimental data, the best indicators were found in sample 2 at an emulsion concentration of 1.0 %. When using an emulsion based on zinc oxide nanoparticles, the samples of active films have improved barrier properties and high antioxidant activity. The use of a Pickering emulsion based on zinc oxide nanoparticles in the film material makes it possible to obtain a wide range of active food packaging.
