| Abstract: | In this study,the processing conditions of preparing high-load(60%) palm kernel oil microencapsules by spray-drying method were studied.The properties of microencapsules containing oil were also analyzed.The optimum processing conditions were: OSA(octenylsuccinate) modified starch and maltodextrin ratio 2∶ 1,xanthan gum content 0.15%;emulsification rate 9500 r/min for 3 min;homogenization twice at pressure of 40 MPa;inlet and outlet air temperature 190℃,85~95℃ respectively.The high-load palm kernel oil microencapsules prepared by this method were white powder with good physicochemical properties. |
