Abstract: The classification, amino acid composition and subunit composition of peanut proteins and extraction methods for major peanut proteins (arachin, conarachinⅡ and conarachin I), including cryoprecipitation and ammonium sulfate precipitation, are overviewed here. The functional properties of peanut proteins, including protein solubility, emulsifying capacity, foaming capacity, gelatin properties, and so on, are reviewed. Finally, problems encountered in studying peanut proteins are summarized and further research directions are proposed. 

Key words: peanut protein, composition, extraction method, functional properties
