Experimental Study On The Microencapsulation Process Of Ginger Oleore

Ginger Oleore was microencaPsulated with the method of spray-drying using thesoybean protein and maltodextrin as the principal wall-material. The process includesmainly mixing material, homogenization and spay-drying. The microcapsuleproperties were affected by the wall-to-wall material ratio, the core materialconcentration, homogenizing condition, the spay-drying temPerthee and so on.Through the experimeflt, The suitable conditions for preparation of spray-dryingmicrocaPsules Which retelltion was 94.4% was spay-drying temperature of 100C. Thesolid material concentration was 20%, and the maltodextrin-to-soybean material ratiowas 2:1, and the core material concelltration was 2.11%. After being homogenized 4times by homogenizer Which homogenizing pressure was 30MPa, the mixing materialwill be well-proportioned. The outer structure of the microcaPsules was affected bythe wall-to-wall material ratio and the spay-drying temperature. The averaged pediclediameter and solubility of microcaPsules were affected by the wall-to-wall materialratio and the solid material concentration.
