Abstract :
The study investigated the characteristics of chitosan-maltodextrin (CS-MD) nanoparticles incorporating coconut shell liquid smoke at various formulations. Chitosan-maltodextrin nanoparticles were prepared with the addition of 1.0% sodium tripolyphosphate (TPP) into a solution of liquid smoke. Sample consisting of CS-MD nanoparticles in 1.0% acetic acid without liquid smoke was used as a control. CS-MD nanoparticles were also evaluated at elevated temperatures (40 and 50°C) for 15 min. The CS-MD nanoparticles with the liquid smoke resulted in the range of pH from 2.41 to 3.02; viscosity 10.83 cP - 11.77 cP; particle size 1.3 nm - 12.7 nm and the zeta potential (-6.53) mV – (+3.12) mV. While, the control CS-MD nanoparicles without coconut shell liquid smoke showed pH 3.09; viscosity 11.17 cP; particle size 343.86 nm and the zeta potential (+5.17) mV.
