Optimization of Carnauba Wax fine Particle Production via Response Surface Methodology for Application in Edible Films

Environmental concerns over synthetic plastics have driven the development of biodegradable edible films for food packaging. However, these films often lack sufficient moisture resistance. This study optimized carnauba wax nanoparticle production via Response Surface Methodology (RSM) using spontaneous emulsification. Factors such as pH, temperature, and emulsifier concentration were investigated to achieve minimal particle size and stable emulsions. The optimal conditions (pH: ۹, temperature: ۴۵°C, Tween ۸۰: ۰.۱%) produced stable emulsions with a mean particle size of ۱.۵ µm and excellent electrostatic stability. The results demonstrate the potential of incorporating these emulsions into biopolymer-based edible films, offering enhanced functionality and sustainability.
