Based on electro-characteristic and double electric layers models, directional mechanisms of soy protein molecular are analyzed for the first time on DC heating condition. After the main factors which effect soy protein gels transparency and strength being studied on DC heating condition, the different affects on soy protein gels transparency and strength by DC heating and water bath heating are analyzed and compared, and the transparent mechanisms of soy protein gels are further explored. In addition to temperature action as water bath heating, DC heating is added as electric field directional action. As a results, heating rate is increased. Directional range degrees of soy protein molecules are raised. These advantage the increase of soy protein gels transparency and strength. Microstructures of soy protein gels forming on DC heating condition are observed by SEM and the results showed that ordered structure of transparent soy protein gels on DC heating condition is more ordered than that of transparent soy protein gels on water bath heating condition.
