Abstract

The coatings on aluminum beverage can lid interiors can be prone to long-term degradation due to the high impact forces during fabrication and the corrosive nature of beverages. Multi-month tests are required to assess their resistance to this degradation. This study aims to present an innovative can lid coating testing method that incorporates in-situ Electrochemical Impedance Spectroscopy (EIS) monitoring under real-world conditions and with actual beverages. A robust testing chamber was meticulously engineered to house the 3D-shaped lid and maintain the conditions found in a beverage can. Experiments were conducted at stressed and non-stressed conditions, assessing different coatings and different beverages. The developed method has the potential to mimic the multi-month pack tests and offers a quicker, more insightful, and less laborious alternative for the lid coating degradation assessment. Ultimately, this method could help in improving the longevity and quality of aluminum beverage cans.

通过电化学阻抗光谱仪持续监测现实条件下铝制饮料罐盖降解情况的平台

由于铝制饮料罐盖内壁在制造过程中受到较大的冲击力以及饮料的腐蚀性，其涂层很容易发生长期降解。为了评估涂层的抗降解能力，需要进行为期数月的测试。本研究旨在介绍一种创新的罐盖涂层测试方法，该方法结合了电化学阻抗谱（EIS）原位监测技术，可在实际条件下使用实际饮料进行测试。我们精心设计了一个坚固耐用的测试室，以容纳三维形状的盖子，并保持饮料罐中的条件。实验在受压和非受压条件下进行，评估了不同的涂层和不同的饮料。所开发的方法具有模仿长达数月的包装测试的潜力，为罐盖涂层降解评估提供了一种更快、更有洞察力、更省力的替代方法。最终，这种方法将有助于提高铝制饮料罐的寿命和质量。

期刊介绍： Food packaging is crucial for preserving food integrity throughout the distribution chain. It safeguards against contamination by physical, chemical, and biological agents, ensuring the safety and quality of processed foods. The evolution of novel food packaging, including modified atmosphere and active packaging, has extended shelf life, enhancing convenience for consumers. Shelf life, the duration a perishable item remains suitable for sale, use, or consumption, is intricately linked with food packaging, emphasizing its role in maintaining product quality and safety.
