For this purpose, an experimental response surface design was proposed using the numerical optimization method, with the study factors (A) inlet air temperature (130; 140; 150 °C) and (B) feed flow rate ( 500; 600; 700ml/h). The materials used as wall material to form the polymeric matrix were gum arabic and maltodextrin. Based on the experimental runs produced by the design, the data for each response variable (% humidity; % yield; % microencapsulation efficiency) were determined, resulting in the microencapsulation process being optimized with an air inlet temperature equal to 150° C and a feed flow rate equal to 500 ml/h, parameters in which a yield of 92.14%, a microencapsulation efficiency of 91.34% and a humidity of 2.14% are obtained, indicating the success of the process. Said optimized parameters show that factor A has a more significant influence than factor B during the microencapsulation process, since as the temperature increases, an almost instantaneous elimination of the water present in the emulsion occurs, thus leaving the bioactive compound trapped inside the microcapsule. |
