| Abstract: | Tensile strength, oil vapor permeability properties and microstructure were studied on the film of soybean isolated protein treated with differentultrasonic power. The results showed that tensile strength and oil vapor permeability properties were improved and microstructure became well mixed after being treated by ultrasonic with the power of 1 000 W for 10 s. |
