Applications of polycaprolactone in the food industry: A review

Abstract

The food industry is always looking for ways to innovate in elaborating and packaging food products to ensure the consumer receives the highest quality. The new proposals include the use of polycaprolactone (PCL), a commonly used biopolymer that is soluble in many organic solvents. The PCL features can be modified by forming blends with other polymers and bioactive molecules to expand their applications in the food industry. For instance, there have been developments in packages and active substances that incorporate microcapsules based on PCL. This review explores the applications of PCL in the food industry, encompassing its role as a biodegradable active package and as an encapsulating agent. The review underscores the potential of this polymer in the context of the food industry.
