Arraillaria mellea was hydrolyzed with the enzyme hydrolytic in which papain and celluclase were added simultaneously. The conditions of extraction were screened with the content of α-amino nitrogen and sensory evaluation as marker by one-factor experiment and oahogonal experiment designed. Having established optimal hydrolyzing condition: ratio of celluclase and papain1:5, temperature 55℃, pH7.0 for 5 hours.
