Gelatin was extracted from fish scales in this work, in an attempt to valorise abundant and available fishery by-products as an approach towards a more circular economy. With this strategy in mind, fish scale gelatin was used to prepare active films. In this regard, the development of advanced materials from gelatin involves its modification to enhance functional properties, particularly barrier properties, to achieve the requirements for specific value-added purposes, such as food or pharmaceutical/biomedical applications. The improvement of those functional properties can be achieved by means of chemical cross-linking processes. In this context, non-enzymatic reactions were carried out with the addition of fructose and ascorbic acid into gelatin film forming formulations, and cross-linking was induced by a heat-treatment. These cross-linking reactions resulted in higher barrier features, especially for those films prepared with ascorbic acid.
在本研究中，明胶是从鱼鳞中提取的，旨在将丰富且可得的渔业副产品加以利用，以此迈向更循环的经济模式。基于这一策略，鱼鳞明胶被用于制备活性薄膜。就此而言，利用明胶开发先进材料涉及对其进行改性以增强功能特性，特别是阻隔性能，从而满足特定增值用途的要求，如食品或制药/生物医学应用。这些功能特性的改善可通过化学交联过程来实现。在此背景下，在明胶成膜配方中添加果糖和抗坏血酸进行非酶反应，并通过热处理诱导交联。这些交联反应产生了更高的阻隔特性，尤其是对于用抗坏血酸制备的薄膜而言。
