Abstract

Sustainable natural product-based microstructured systems and biopolymers are strong candidates for use in crop protection. Lignin and gelatin microcapsules loaded with orange essential oil were developed with spray-drying in order to enhance its potential. We evaluated the microparticle controlled release mechanisms, biological effects, structural and thermal properties. A quantitative method using headspace-gas chromatography was developed and evaluated for the controlled release of the essential oils. Controlled release studies showed a linear relationship between the biopolymer and essential oil concentrations when retaining volatile compounds. Thermal analyses demonstrated increases in essential oil stability when microencapsulated, especially for lignin as a biopolymer. These results showed that biopolymer type was the main factor influencing quality analysis parameters. Finally, microcapsules loaded with orange essential oil were applied in a bioassay, and showed gains in toxicity against Spodoptera frugiperda compared to non-encapsulated oil. (AU)
