Proteomic profiling of the coagulation of soymilk proteins induced by magnesium chloride

► We identified twenty-four soymilk proteins in the soymilk proteome. ► We characterized the MgCl2-induced coagulation of the identified soymilk proteins. ► The 7S and 11S subunits were coagulated by the addition of 5 mM MgCl2. ► A proteomics-based approach is a useful method for the analysis of soymilk proteins.
