Abstract:

Microcapsules of paprika oleoresin were prepared by spray-drying technology using paprika oleoresin as the core material, modified starch and gelatin as the wall materials, dextrin as the filler. Results indicated the optimal microencapsulation conditions were 2:1 of modified starch to gelatin ratio, 40% of paprika oleoresin content, and 45% of emulsion solid content. Moreover, the optimal conditions for spray-drying were also investigated through orthogonal array design experiments, which were 180 ℃ for inlet temperature, 80-90 ℃ for outlet temperature, 20.0 ml/min for flux rate and 0.15 MPa for inlet air pressure.

Key words: paprika oleoresin, microencapsulation, spray-drying
