Abstract
Background
The increasing environmental concerns surrounding conventional plastic packaging and the demand for higher food safety and quality have led to a surge in the development of bio-based smart food packaging. These novel packaging materials are featured with renewability and biodegradability, and at the same time, possess active and intelligent functionalities to enable extended food shelf life. Despite numerous advances, challenges remain in the feasibility of industrial production.
Scope and approach
This review examines the current state of bio-based smart food packaging, focusing on the most used raw materials and fabrication methods and their unique functionalities. Special attention is given to innovative production techniques like 3D printing and electrospinning, exploring their potential scalability and enhanced properties. This review also delves into the key applications of bio-based smart packaging materials in pH/gas, temperature, humidity, enzyme-responsive systems, and their multi-responsive capabilities.
Key findings and conclusions
Significant progress has been made in developing bio-based smart packaging materials that can respond to environmental stimuli. Particularly, pH- and gas-responsive packaging offers promising solutions for food spoilage detection. However, the commercial applications of novel packaging materials and production techniques need to be promoted by considering the cost, the scalability, the potential benefits, and the regulations.
期刊介绍：
Trends in Food Science & Technology is a prestigious international journal that specializes in peer-reviewed articles covering the latest advancements in technology, food science, and human nutrition. It serves as a bridge between specialized primary journals and general trade magazines, providing readable and scientifically rigorous reviews and commentaries on current research developments and their potential applications in the food industry.
Unlike traditional journals, Trends in Food Science & Technology does not publish original research papers. Instead, it focuses on critical and comprehensive reviews to offer valuable insights for professionals in the field. By bringing together cutting-edge research and industry applications, this journal plays a vital role in disseminating knowledge and facilitating advancements in the food science and technology sector.
