Abstract

The production of fruit-film packaging has attracted increasing attention in scientific research due to the packaging’s environmentally friendly, nontoxic, and edible characteristics. The development of alternative packaging contributes to both minimizing the environmental impacts caused by the large consumption of non-biodegradable plastics and favoring the reduction of postharvest loss/waste of fruit. In addition, these fruit films have the potential to be functional packages due the presence of antioxidant and antimicrobial compounds that can migrate to the food matrix, acting as natural additives. The use of fruit puree to develop biodegradable films can be simpler and more practical than the developed of films from fruit flour or extracts, reducing the time, energy, and resources necessary to prepare the film-forming solution. A better understanding of the mechanical properties, bioactive compounds, and potential applications is interesting in terms of prospecting new specific ways to produce and use these films. In this study, we briefly review the general aspects of fruit puree films, highlighting their characterization for use as food packaging.

摘要

果膜包装的生产由于其环保、无毒、可食用等特点，越来越受到科学研究的关注。替代包装的开发有助于最大限度地减少因不可生物降解塑料的大量消耗而造成的环境影响，并有助于减少水果的收获后损失/浪费。此外，这些水果薄膜有可能成为功能性包装，因为抗氧化剂和抗菌化合物的存在可以迁移到食物基质中，作为天然添加剂。使用果泥开发可生物降解的薄膜比使用果粉或提取物开发薄膜更简单、更实用，减少了制备成膜溶液所需的时间、能源和资源。更好地了解机械性能、生物活性化合物和潜在应用在探索生产和使用这些薄膜的新特定方法方面很有趣。在这项研究中，我们简要回顾了果泥薄膜的一般方面，重点介绍了它们用作食品包装的特性。
