Abstract：
The improper disposal of petroleum-based plastics has been associated with detrimental environmental consequences, such as the proliferation of microplastic pollution and increased emissions of greenhouse gases (GHGs). Consequently, biopolymers have emerged as a highly regarded alternative due to their environmental-friendly attributes and versatile range of applications. In response to consumer demands for safer food options, sustainable packaging, and escalating environmental concerns, the food sector is increasingly adopting biopolymers. Further, in the recent decade, the usage of active or functional biopolymers has evolved into smart biopolymers that can transmit real-time data to consumers. This review covers key topics such as antimicrobial and biodegradable packaging, edible coatings and films, incorporation of scavengers and bioactive substances that prolong the shelf life and guard against moisture and microbial contamination. The paper also discusses the development of edible cutlery as a sustainable substitute for plastic, the encapsulation of bioactive substances within biopolymers, 3-D food printing for regulated nutrition delivery and thickening and gelling agents that improve food texture and stability. It also discusses the integration of smart polymer functions, demonstrating their importance in guaranteeing food safety and quality, such as biosensing, pH and gas detection, antibacterial characteristics, and time-temperature monitoring. By shedding light on market trends, future scope, and potentialities, this review aims to elucidate the prospects of utilizing biopolymers to address sustainability and quality concerns within the food industry effectively.
摘要：
石油基塑料的不当处置与有害的环境后果有关，例如微塑料污染的扩散和温室气体（GHG）排放的增加。因此,由于其环境友好的属性和广泛的应用范围，生物聚合物已成为备受推崇的替代品。为了响应消费者对更安全食品选择的需求，可持续包装，不断升级的环境问题，食品行业越来越多地采用生物聚合物。Further,在最近的十年里，活性或功能性生物聚合物的使用已经发展成为可以向消费者传输实时数据的智能生物聚合物。这篇综述涵盖了抗菌和可生物降解包装等关键主题，可食用涂层和薄膜，掺入清除剂和生物活性物质，延长保质期，防止水分和微生物污染。本文还讨论了可食用餐具作为塑料的可持续替代品的发展，将生物活性物质封装在生物聚合物中，3-D食品打印，用于调节营养输送和增稠剂以及改善食品质地和稳定性的胶凝剂。它还讨论了智能聚合物功能的集成，证明了它们在保证食品安全和质量方面的重要性，比如生物传感，pH和气体检测，抗菌特性，和时间温度监测。通过揭示市场趋势，未来的范围，和潜力，这篇综述旨在阐明利用生物聚合物有效解决食品工业中可持续性和质量问题的前景。
