Abstract:

The effects of β-conglycinin and glycated β-conglycinin on the thermal aggregation of glycinin was studied. Evidence was presented to suggest that β-conglycinin and glycated β-conglycinin could both prevent thermal aggregation of glycinin in 30 mmol/L Tris-HCl buffer solution (β-Me exsisted). Further, addition of glycatedβ-conglycinin prevented thermal aggregation of glycinin more obviously than β-conglycinin. The results also indicated that the inhibitory mechanism of glycated β-conglycinin on glycinin aggregation was not as same as that of β-conglycinin due to charge-charge interactions.

Key words: β-conglycinin, glycinin, glycosylation, thermal aggregation
