Oilseeds are receiving much attention as sources of edible protein, even though some are generally low in certain essential amino acids such as lysine, methionine, tryptophane, and/or isoleucine. One of the best ways for correcting the amino acid balance is to blend two or more oilseed proteins. Defatted peanut flour (low in methionine) and a citrus seed flour reportedly high in methionine were blended and evaluated chemically for protein solubility, amino acid composition, gel electrophoretic protein patterns and methionine and available lysine levels. Solubility of peanut proteins is much higher than that of citrus seed proteins, precluding the use of blends in preparation of protein co-isolates for some types of beverages. Because of their properties, these blends would probably find better use in cloudy, fruit-flavored, or milk-type beverages or in solid food items such as meat extenders, bakery goods, dry soup, or gravy mixes.
