Cutin is the main component of plant cuticles constituting the framework that supports the rest of the cuticle components. This biopolymer is composed of esterified bi- and trifunctional fatty acids. Despite its ubiquity in terrestrial plants, it has been underutilized as raw material due to its insolubility and lack of melting point. However, in recent years, a few technologies have been developed to obtain cutin monomers from several agro-wastes at an industrial scale. This review is focused on the description of cutin properties, biodegradability, chemical composition, processability, abundance, and the state of art of the fabrication of cutin-based materials in order to evaluate whether this biopolymer can be considered a source for the production of renewable materials.
角质是构成支撑其余角质层成分的框架的植物角质的主要成分。这种生物聚合物由酯化的双官能和三官能脂肪酸组成。尽管它在陆生植物中无处不在，但由于其不溶性和缺乏熔点，它一直未被充分利用作为原料。然而，近年来，已经开发了一些技术，可以在工业规模上从几种农业废弃物中获得角质单体。本综述重点介绍了角质的性质、生物降解性、化学组成、可加工性、丰富度以及角质基材料的制造技术的现状，以评估这种生物聚合物是否可以被认为是生产可再生材料的来源。
