In this study, gelatin-gum arabic microcapsules containing lauric acid were prepared for thermal energy storage applications. Lauric acid and gelatin-gum arabic were used as the core material and shell material, respectively. The synthesized microcapsules were analyzed using differential scanning calorimetry (DSC) for thermal characterization. DSC analysis revealed that the melting and freezing points of the synthesized microcapsules were determined to be 41.35°C and 39.76°C, respectively, with a latent heat storage capacity of 171-173 J/g. The thermal analyses confirm the successful microencapsulation of lauric acid and its suitability for thermal energy storage applications.
