The aim of this review is to provide an overview of recent findings related to bacterial cellulose application in bio-packaging industry. This constantly growing sector fulfils a major role by the maintenance of product safety and quality, protection against environmental impacts that affect the shelf life. Conventional petroleum-based plastic packaging are still rarely recyclable and have a number of harmful environmental effects. Herein, we discuss the most recent studies on potential good alternative to plastic packaging-bacterial nanocellulose (BNC), known as an ecological, safe, biodegradable, and chemically pure biopolymer. The limitations of this bio-based packaging material, including relatively poor mechanical properties or lack of antimicrobial and antioxidant activity, can be successfully overcome by its modification with a wide variety of bioactive and reinforcing compounds. BNC active and intelligent food packaging offer a new and innovative approach to extend the shelf life and maintain, improve, or monitor product quality and safety. Incorporation of different agents BNC matrices allows to obtain e.g., antioxidant-releasing films, moisture absorbers, antimicrobial membranes or pH, freshness and damage indicators, humidity, and other biosensors. However, further development and implementation of this kind of bio-packaging will highly depend on the final performance and cost-effectiveness for the industry and consumers.
本综述的目的是概述细菌纤维素在生物包装行业应用的最新研究成果。这个不断发展的领域通过维护产品安全和质量、防止影响保质期的环境影响发挥着重要作用。传统的石油基塑料包装仍然很少可回收，并且有许多有害的环境影响。在此，我们讨论了关于塑料包装潜在良好替代品——细菌纳米纤维素（BNC）的最新研究，它是一种生态、安全、可生物降解且化学纯净的生物聚合物。这种生物基包装材料的局限性，包括相对较差的机械性能或缺乏抗菌和抗氧化活性，可以通过用各种生物活性和增强化合物对其进行改性来成功克服。BNC活性和智能食品包装提供了一种新的创新方法来延长保质期并维持、改善或监测产品质量和安全。在BNC基质中加入不同的试剂可以得到例如抗氧化剂释放膜、吸湿剂、抗菌膜或pH、新鲜度和损伤指示剂、湿度及其他生物传感器。然而，这种生物包装的进一步发展和应用将高度依赖于其对行业和消费者的最终性能和成本效益。
