Abstract
An analysis of the resource potential of macroalgae wash-outs onto the Baltic Sea coast has been performed. A critical review of the applications of polysaccharides extracted from Furcellaria lumbricalis macroalgae wastes washed ashore is presented. Optimal extraction conditions have been established to ensure maximum yield of polysaccharides. It is recommended to use alkaline hydrolysis with potassium hydroxide 0.1 M, process time is 60 minutes. Recipes of biopolymer films with the necessary physical, mechanical and antibacterial properties have been determined. It was concluded that the production of biofilms with antibacterial properties with the addition of vegetable oils is promising. Their use with application directly to the product will provide a longer shelf life without significant changes in organoleptic properties.
