Abstract: A new process for the acid dissolution of soybean meal under pressure was studied.The optimum conditions for the dissolution process were studied with solubility of soybean meal through orthogonal test.The results showed that the optimum dissolution conditions are:sulfuric acid mass fraction,20%;reaction time,20 min;temperature (pressure),110 ℃ (0.104 5 MPa);liquid to solid mass ratio,10.Surface activity test of the dissolved soybean meal showed that the product displays good surface activity.

Key words: soybean meal, dissolution, surface activity
