Plastic pollution is increasing day by day and the search for new, environmentally friendly products continues. Herein, for the first time, different degrees of mucilage were obtained from chia seeds and the film-forming behavior of levan biopolymer with these mucilages was investigated. Glycerol and sorbitol were used as plasticizers in the film design. Films prepared with sorbitol were characterized physically, mechanically and morphologically. The antioxidant and antimicrobial effects of the films were examined. The films formed as nanocomposites of levan and chia seed mucilages obtained at different temperatures (25 °C, 55 °C and 80 °C) exhibited structurally and mechanically different properties. It was observed that the films obtained with chia mucilages and levan preserved their antibacterial properties but lost their antifungal properties. In addition, quorum sensing property of the mucilage obtained at 55 °C during the investigation of the antibacterial property was reported for the first time with this study. The levan-based chia seed mucilages films obtained have the potential to be used in industrial and medical fields, and the nature-friendly nature of these films is very important for our green world.
塑料污染日益严重，人们继续寻找新的环保产品。在此，我们首次从奇亚籽中获得了不同程度的黏液，并研究了这些黏液与藜芦醇生物聚合物的成膜行为。甘油和山梨糖醇被用作薄膜设计中的增塑剂。用山梨糖醇制备的薄膜在物理、机械和形态学方面进行了表征。研究了薄膜的抗氧化和抗菌作用。在不同温度（25°C、55°C 和 80°C）下形成的作为藜芦醇和奇亚籽黏液纳米复合材料的薄膜表现出结构和机械性能的不同。观察到用奇亚黏液和藜芦醇制成的薄膜保持了其抗菌性能，但失去了抗真菌性能。此外，本研究首次报道了在研究抗菌性能时，在 55°C 下获得的黏液的群体感应特性。用藜芦醇制备的奇亚籽黏液薄膜具有在工业和医疗领域应用的潜力，这些薄膜的环保性质对我们的绿色世界非常重要。
