摘要

本文研究了海藻酸钙水凝胶包埋银纳米粒子(AgNPs)涂层，该涂层最近被开发用于fiordilatte奶酪的抗菌活性包装。用x射线光电子能谱对涂层进行了化学表征。同时，通过ICP-MS分析测定银的释放量。结果表明，银离子在卤水和紫丁香奶酪中均有释放，证实了涂层的抗菌活性。这些初步结果标志着银在食品包装工业中的应用又向前迈进了一步。获得的数据正在评估中。

Analytical characterization of silver-nanoparticle antimicrobial coatings for fiordilatte cheese

Coatings consisting of calcium alginate hydrogel embedding silver nanoparticles (AgNPs), recently developed as a antimicrobial active packaging for fiordilatte cheeses, were studied. The coatings were chemically characterized by X-ray photoelectron spectroscopy. Also, silver release was measured through ICP-MS analyses. Results shows that silver ions are released both in brine and in fiordilatte cheese, confirming the antimicrobial activity of coatings. These preliminary results represent a step forward in the application of silver in food packaging industry. Obtained data are under evaluation.
