Abstract: Fruit pulp of papaya( Carica papaya L.) was used as raw material to prepare papaya powder by using the method of microwave-assisted foam mat drying. The papaya pulp was whipped into foam mat with foaming agent for microwave drying. The foaming agents,glycerol monostearate( GSM) and soy protein isolate( SPI)were added into the pulp at different concentrations to select an optimum formulation of foaming agent,and the pulp foam mat was dried under microwave to optimize parameters for the microwave foam mat drying technology.The papaya fruit pulp produced maximum foam expansion with good foam stability when it was whipped into foam mat with 6. 83% GMS and 4% SPI. The optimal conditions for microwave foam mat drying of papaya pulp were microwave power 578 W,pulp foam thickness 4. 90 mm,and drying time 6. 65 min.
