摘要

电纺丝是膜制造领域中一项备受探索的技术,尤其是在活性食品包装领域。尽管这种技术得到了广泛应用,但与传统塑料相比,有关生物材料可行性的实际经济评估方面的文献仍存在很大差距。本研究试图通过开发电纺香兰素负载玉米蛋白膜来填补这一空白,以评估其在抗菌活性、生物降解性和经济可行性方面的功效。从可持续发展的角度来看,新开发的膜显示出令人印象深刻的抑制酵母生长 75% 的能力,仅 7 天就能观察到完全降解。这凸显了它们在减轻环境影响和推广环保型包装解决方案方面的潜力,从而在保持安全和质量的同时,减少塑料垃圾和食物损失。然而,这些膜在经济上的可持续性仍然是一个公开的挑战。很明显,主要瓶颈并不在于创新的生产技术,而在于原材料的价格,特别是天然添加剂的价格。这凸显了机构采取支持性措施,鼓励向可持续包装替代品过渡的必要性,以及全面循环概念的重要性。这项工作表明,实现欧洲零塑料废弃物的目标需要做出具体努力。

Sustainable Development of Biodegradable Antimicrobial Electrospun Membranes for Active Food Packaging and Economic Analysis

Sustainable Development of Biodegradable Antimicrobial Electrospun Membranes for Active Food Packaging and Economic Analysis

Sustainable Development of Biodegradable Antimicrobial Electrospun Membranes for Active Food Packaging and Economic Analysis

Electrospinning is a much-explored technique in the membrane fabrication field, particularly in active food packaging. Despite the widespread use of this technique, there remains a significant gap in the literature regarding the actual economic evaluation of the viability of biomaterials compared to traditional plastics. This study seeks to fill this gap by developing electrospun, vanillin-loaded zein membranes to evaluate their efficacy in terms of antimicrobial activity, biodegradability, and economic viability. From a sustainability perspective, the newly developed membranes show an impressive ability to inhibit yeast growth by 75%, with complete degradation observed in only 7 days. This underscores their potential to mitigate environmental impact and promote environmentally friendly packaging solutions to reduce both plastic waste and food loss while maintaining safety and quality. However, the economic sustainability of these membranes is still an open challenge. It becomes clear that the main bottleneck does not lie in the innovative production technology, but rather in the prices of raw materials, particularly natural additives. This underscores the need for supportive measures from institutions to incentivize the transition to sustainable packaging alternatives and the importance of the full circularity concept. This work shows that achieving the European goal of zero plastic waste requires concrete efforts.
