摘要: Microencapsulation is a novel approach to protect the spice oleoresin from light-, heat- and oxidation-associated degradation. Nevertheless, little information on microencapsulation of solvent-extracted star anise oleoresin is available. This study aimed to investigate the efficiency of spray-drying microencapsulation of solvent-extract star anise oleoresin with the use of maltodextrin and soy protein as wall materials at different temperatures and to evaluate the characteristics of the resultant microencapsules. Through mathematical modeling, spray-drying encapsulation of 5% oleoresin with 20% maltodextrin and 7.5% soy protein at an inlet temperature of 180C was considered the best to yield highly heat-, light- and humidity-stable microencapsules that had a regular shape with a complete, round, smooth, compact and noncracking exterior wall and normal internal structures.
