INFLUENCE OF EMULSION COMPOSITION AND SPRAY DRYING CONDITIONS ON MICROENCAPSULATION OF TILAPIA OIL
Influence of processing conditions on microencapsulation of tilapia oil by spray drying was studied.Trehalose, gelatin, sucrose and xanthan were used as wall materials.The experimental parameters of spray drying such as inlet air temperature, solid content, drying air flow rate and atomizing pressure were optimized using a central composite design.Encapsulation efficiency and lipid oxidation were analyzed as responses factors.Bulk density, powder morphology and particle size were also analyzed.Trehalose improved the glass transition temperature of wall material significantly and avoided the oxidation of fish oil.Encapsulation efficiency was up to 90％ under optimum conditions which were inlet temperature 120℃, drying air flow rate 0.66m3/min and the spray pressure 100kPa.
