Method for preparing legumes powder using aquafaba

A method for preparing aquafaba powder for edible emulsifier, comprising:

• selecting legumes, wherein the legumes are soybeans;
• washing the selected soybeans with distilled water and then drying the soybeans at room temperature of 22° C.;
• soaking the soybeans in distilled water at 4° C. for 16 hours, wherein the soybeans are added along with distilled water in a glass jar at a ratio of 1:3 and sealed;
• separating the soaked soybeans and soaking liquid using a strainer;
• heating the separated soybeans at 118° C. while being pressurized by a pressurizing/heating device to obtain soybeans and aquafaba;
• cooling the obtained soybeans and aquafaba at 22° C. for 24 hours;
• separating the cooled soybeans and the aquafaba after the cooling process using a strainer;
• and
• obtaining aquafaba powder by freezing the separated aquafaba at −20° C. and then vacuum drying the frozen aquafaba in a dryer for 48 hours,
• wherein the separated soaked soybeans are cooked by heating for 90 minutes at 118° C. while being pressurized to 70 to 80 kPa by the pressurizing/heating device.
