Optimization of coating ratio and homogenization conditions in the production of coconut shell liquid smoke nanoparticles

Abstract

The liquid smoke in liquid form is considered less practical and susceptible to damage to phenolic compounds during storage. Liquid smoke encapsulation technology is expected to be able to overcome the problem of handling liquid smoke. This study aimed to determine the optimum conditions for the manufacture of liquid smoke nanoparticles in terms of the particle size distribution produced. The ratio of arabic gum and maltodextrin concentration, homogenization speed and homogenization time were optimized using the Box-Behnken Response Surface Methodology (RSM) experimental design. The response used in this study is the particle size distribution (z-average). Based on the results of the study, the optimum conditions for the manufacture of liquid smoke nanoparticles were obtained at a concentration ratio of gum arabic and maltodextrin 12:88, a homogenization speed of 4000 rpm and a homogenization time of 3 mins, with a particle size distribution (z-average) 78.53±1.48 nm.
