Objective To extract almond protein by phosphate method from among dregs,and confirm the best process conditions. Methods Based on designing and analyzing single factor experiment and orthogonal experiment,the dregs and phosphate solution were mixed, heated in water bath and stirred, centrifugally separated, absorbance of liquid supernatant was measured, and extraction rate was calculated to confirm process parameter. Results The process conditions of extracting almond protein by phosphate method is temperature 50℃, feed liquid ratio 1:30,time 1.0 h, salting strength 0.01mol/L,and protein extract rate is 72%. Conclusions Extraction of almond protein by phosphate method will not destroy protein and is high in extraction rate.
