A method for fractionating a soybean protein into highly pure 7S globulin and 11S globulin efficiently in an industrial scale is provided, said method comprising warming a solution containing a soybean protein under a weakly acidic condition followed by fractionating at pH 5. More importantly the low strain rate thermomechanical treatment imparts a high degree of commercially valuable elasticity. The data is transferred in a vertical blanking time period of the video output data. Multiple locator elements may be deployed to further define the tissue volume along additional paths defining the tissue volume border that do not penetrate the volume.
