The aim of this paper is to evaluate the physicochemical and microbiological properties of active thermoplastic starch-based materials. The extract obtained from grape cane waste was used as a source of stilbene bioactive components to enhance the functional properties of thermoplastic starch (TPS). The biomaterials were prepared by the compression molding technique and subjected to mechanical, thermal, antioxidant, and microbiological tests. The results showed that the addition of grape cane extract up to 15 wt% (TPS/WE15) did not significantly influence the thermal stability of obtained biomaterials, whereas mechanical resistance decreased. On the other side, among all tested pathogens, thermoplastic starch based materials showed antifungal activity toward and antimicrobial activity toward , suggesting potential application in food packaging as an active biomaterial layer.
本文旨在评估基于热塑性淀粉的活性材料的物理化学和微生物特性。从葡萄藤废料中提取的物质被用作芪类生物活性成分的来源，以增强热塑性淀粉（TPS）的功能特性。通过压缩成型技术制备生物材料，并对其进行机械、热学、抗氧化和微生物测试。结果表明，添加高达 15wt%的葡萄藤提取物（TPS/WE15）不会显著影响所获得生物材料的热稳定性，而机械阻力则降低。另一方面，在所测试的所有病原体中，基于热塑性淀粉的材料对 表现出抗真菌活性，对 表现出抗菌活性，表明其在食品包装中作为活性生物材料层的潜在应用。
