Objective: To study the effect of steam-heated procedure on immunogenicity of major antigenic proteins in soybean. Method: Twelve newborn calves were randomly divided into 3 groups (Group A, B and C). Each group of the calves were fed on the diets containing raw soybean flour, heated soybean flour and whole milk, respectively. The glycicin, ?-conglycinin and neighbor collection as antigens, antibodies specific to soy allergens were detected by ELISA. Results: (1) The weight gain was A

The effect of urea, guanidine hydrochloride and sodium dodecyl sulphate on glycinin, the high molecular weight protein fraction from soybean has been investigated by analytical ultracentrifugation. Urea and guanidine hydrochloride dissociate the protein to a '2S' protein through the intermediary 7S and 4S proteins. However, in sodium dodecyl sulphate the protein directly dissociates to a 2S protein. Analysis of the data by calculation of per cent fraction and S20,w value indicates that dissociation and denaturation of glycinin occur simultaneously in the presence of the above reagents but to different extents.
