This study was investigated to determine the functional properties of mugbean protein isolates(MPI) from sunhwa-nogdu(SH) and conventional mungbean varieties(C). MPI were prepared from defatted mungbean flour by extraction with 0.1N NaOH, precipitation at pH 4.5, washing of dispersed precipitate with buffer solution and distilled water, and subsequent freeze-drying. Crude protein content of MPI was in the range of $88.7{\sim}91.3%$. The lowest solubility was recorded at $pH\;4{\sim}5$, whereas the best buffering action was in the range of $5.5{\sim}7.5$. On the other hand, gelation of MPI was found to depend on the protein concentration. In the cases of foamability, % volume increase and specific volume were higher for 10 min. with a good whipping ability. And also, the MPI properties of two varieties of SH and C were compared and discussed.
