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.
从大型藻类废弃物中获取生物聚合物薄膜
对冲刷到波罗的海沿岸的大型藻类的资源潜力进行了分析。对从冲上岸的毛鳞藻大型藻类废弃物中提取的多糖的应用进行了严格审查。为确保多糖的最大产量,确定了最佳提取条件。建议使用 0.1 M 氢氧化钾进行碱性水解,工艺时间为 60 分钟。确定了具有必要物理、机械和抗菌性能的生物聚合物薄膜配方。结论是,添加植物油生产具有抗菌性能的生物膜是很有前景的。将其直接应用于产品可延长保质期,而不会明显改变感官特性。
