Study on preparation technology of coconut oil powder

The cold-pressed coconut oil as core material,then the coconut oil powder was prepared by using the emulsify and spray-drying technology.The optimal preparation parameters of coconut oil powder were determined by orthogonal experiments,the optimal parameters were as follows:mass ratio of emulsifier monoglycerides to sucrose esters 1∶4,emulsifier 3.0%,mass ratio of composite wall materials gelatin to porous starch 1∶6,emulsifying temperature70℃,solid concent 20%;homogenity pressure 40 MPa,inlet temperature 195℃,charging rate 20 ml/min. Under the optimum conditions,the oil content was 48%,the surface oil content was 1.81%and the embedding efficiency was 96%.
