Ecologically Сlean Packaging — Edible Film Based on Apple Puree with the Addition of Sodium Alginate

Properties of such "active" shells as edible film materials have been studied. The basis of these coatings are natural polymers - polysaccharides, which can be represented by sodium alginate. Edible films based on natural polymers have a high sorption ability and, when ingested, adsorb and remove metal ions, radionuclides and other harmful substances from the human body. The organoleptic properties, structure, water-absorbing capacity, strength characteristics of double edible films based on apple puree, with inclusion of sodium alginate in one of the layers were studied. Five samples of a film with various kinds of plasticizers were made. It is established that all the films obtained possess good digestibility by the organism due to the content of completely natural components.
