Blueberry is popular among consumers for their unique flavor and rich nutritional content. However, fresh blueberry often has a short shelf life due to microbial contamination and water loss. Existing blueberry preservation methods, such as irradiation, air conditioning, and high-voltage electrostatic fields, have shown certain effectiveness. Nonetheless, their high cost and energy consumption limit their widespread use. Edible composite films, created by incorporating functional substances into an edible film matrix, represent an eco-friendly preservation technology. These films alter the surface microenvironment of fruits by establishing a selective barrier on the fruit's surface, which significantly enhances fruit storage quality. This article provides a comprehensive review of the application of edible composite films in blueberry preservation. By summarizing the spoilage process of blueberry during harvesting and storage, in conjunction with fruit preservation techniques, it explores the feasibility and potential applications of edible composite films. Lastly, it delves into the possibilities and challenges of integrating nanomaterials with edible composite films.

蓝莓以其独特的风味和丰富的营养成分深受消费者的喜爱。然而，由于微生物污染和水分流失，新鲜蓝莓的保质期往往很短。现有的蓝莓保鲜方法，如辐照、空调、高压静电场等，已显示出一定的有效性。然而，其高成本和能源消耗限制了其广泛使用。可食性复合膜是将功能性物质融入可食性薄膜基质中而制成的，代表了一种环保保鲜技术。这些薄膜通过在水果表面建立选择性屏障来改变水果的表面微环境，从而显着提高水果的储存质量。本文对可食性复合膜在蓝莓保鲜中的应用进行了全面综述。通过总结蓝莓在采收和贮藏过程中的腐败过程，结合水果保鲜技术，探讨可食性复合膜的可行性和潜在应用。最后，它深入探讨了将纳米材料与可食用复合膜相结合的可能性和挑战。
