响应型食品包装的研究现状及前景展望

Research Status and Prospects of Responsive Food Packaging

摘要:

响应型食品包装是新型食品包装的主要研究方向。区别于传统包装，响应型食品包装加入了能对食品本身或外界刺激（如光、温度、湿度、pH值）作出反应的刺激响应型材料，当食品包装内或外界条件发生变化时，包装材料发生可观察到的颜色变化或内部的结构变化，使包装内外变化可视化或释放包装材料内的活性物质，从而实现对食品品质的监控和改善。该文结合国内外研究进展，将响应型食品包装根据刺激种类分为物理响应型（光、温度、湿度）、化学响应型（pH值、挥发性硫化物）、生物影响型（微生物和酶）和多响应型四大类，并介绍了不同种类的响应型食品包装的研究进展。最后，综合分析了响应型食品包装在工业化生产中面临来自生产、销售和安全性等多方面的问题与挑战，以及展望响应型食品包装在未来的发展潜力。

Abstract:

Responsive food packaging is a major research direction of new food packaging. Unlike traditional packaging, responsive food packaging is incorporated with stimulus-responsive materials that respond to the food itself or external stimuli (e.g., light, temperature, humidity, pH value). When there are changes in the internal or external conditions of food packaging, the packaging material undergoes observable changes in color or internal structure, so that the internal and external changes in the packaging can be visualized or the active substances inside the packaging material are released, thereby realizing the monitoring and improvement of food quality. Based on the domestic and international research progress, this paper classifies stimuli-responsive food packaging into four categories according to the type of stimuli: physically responsive type (light, temperature, humidity), chemically responsive type (pH value, volatile sulfide), biological impact type (microorganisms and enzymes), and multi-responsive type. Moreover, the research advances of different kinds of responsive food packaging are also presented. Finally, this paper analyzes comprehensively the problems and challenges faced by the responsive food packaging during industrial manufacturing from production, marketing, safety and other aspects o, as well as the development potential of responsive food packaging in the future.
