Abstract:
The major storage proteins in soybeans are glycinin and β-conglycinin，which play important roles in food and nonfood soy protein products due to their different functional properties.In conventional methods，reductants which were bad for consumer health were commonly used to separate soybean glycinin and β-conglycinin.In this study，Rennase made from Mucor pusillus was found to have different characteristics in clotting milk proteins and soy proteins by micro-Kjeldahl method.Rennase was found to clot 11S fraction particularly by further researches.The separation was proved not due to the pH value decreasing caused by the rennase simply and may be relevant to the special clotting effect of rennase，and this characteristic could be used to separating 7S and 11S fractions.
