Advances in oral dissolving film research in the food field

Abstract Oral dissolving film (ODF) emerges as a novel active substance delivery system, offering portability, safety, and compliance. ODF presents superior gastrointestinal absorption compared to conventional food products, making it ideal for providing nutrition and medication support to vulnerable populations such as children, the elderly, and individuals with dysphagia. With promising applications in pharmaceuticals and especially food industry, ODFs offer a highly absorbable method for delivering nutritious and healthy foods. This review underscores the potential of orally dissolving films in active substance delivery, outlining their advantages over traditional oral delivery methods and their current market status. Additionally, the review discusses the formulation procedure, production methods, and quality evaluation methods for film dosage forms of ODFs. Lastly, it examines the limitations of ODFs and speculates on their future trends in the food industry. This study serves as a valuable reference for the development and utilization of orally dissolving films in the food sector. Graphical Abstract
