Abstract:
OBJECTIVETo explore the best technique parameters on preparing evening primrose oil microspheres by spray drying technique.
METHODGC and internal standard method were used to determine the content of gamma-linolenic acid methyl esters, the technological parameters were investigated by orthogonal experimental design with the yield and entrapment rate as indexes.
RESULTThe charging rate as 3 mL x min(-1), atomizing pressure as 100 kPa and the temperature of inlet as 105 degrees C were the best technique parameters.
CONCLUSIONEvening primrose oil microspheres accorded with the expecting demand. The main influencing factor is the charging rate. Spray drying is reasonable and practical for preparing evening primrose oil microspheres.
