Research trends and IP-R&D strategies for the development of clean label materials and processing technologies

Growing consumer awareness of health and safety has accelerated demand for clean label foods characterized by minimal use of synthetic additives. Despite the absence of a globally unified definition or certification system, the clean label market is expanding rapidly and is projected to reach approximately USD 90.5 billion by 2032. This study highlights recent advances in three major research areas of clean label food processing technologies: (i) development of natural preservative materials, (ii) alternative technologies to synthetic nitrites, and (iii) natural seasonings and flavoring agents. Patent analysis further revealed emerging trends such as the use of composite materials to enhance antimicrobial activity, glycation of myofibrillar proteins, plasma-based processing, enzyme-assisted pretreatment, and encapsulation/coating techniques. In addition, current domestic and international regulatory frameworks and intellectual property-R&D strategies are discussed to identify pathways for commercialization and to strengthen global competitiveness. This study is expected to provide a foundation for the Korean food industry to strategically respond to the rapidly evolving clean label market.
