This article aims to analyze the technological developments of packages for chilled or frozen products carrying thermochromic visual indicators to inform the cumulative thermal exposure along logistics chains. Thermochromic visual indicators inform the final consumer whether the product is in real and safe conditions for consumption. Through technological prospecting in the Espacenet and Institute of Industrial Property of Brazil patent databases, 75 documents were selected, and their bibliographic and technical data were analyzed through Iramuteq software to identify the technological fields related to these kinds of packages that contribute most to increasing value. Supported by a literature review, we identified “technological clusters” which promote developing products and processes. The value features related to packages were confronted to technologies found, offering a clear vision of those more advanced and those yet incipient from the value generating point of view. Contrary to intuitive conclusions, technologies employing information on means of measuring and/or indicating temperature are the most frequently present in the patent documents analyzed, comparing to ecological and economic functions.

智能包装与价值创造：基于专利分析的技术发展机遇

本文旨在分析带有热致变色视觉指示器的冷藏或冷冻产品包装的技术发展，以告知物流链中的累积热暴露。热致变色视觉指示器告知最终消费者产品是否处于真实且安全的消费条件下。通过在Espacenet和巴西工业产权局专利数据库中进行技术勘探，筛选出75篇文献，并通过Iramuteq软件对其文献目录和技术数据进行分析，以确定与此类专利包相关的对增值贡献最大的技术领域。在文献综述的支持下，我们确定了促进产品和流程开发的“技术集群”。与软件包相关的价值特征与所发现的技术相对应，从价值产生的角度提供了更先进和尚处于萌芽阶段的清晰愿景。与直观的结论相反，与生态和经济功能相比，采用测量和/或指示温度的方法信息的技术在分析的专利文件中最常见。
