Cell wall material (CWM) from soaked field pea cotyledons was quantitatively isolated (6.85 g/100 g of peas, db) by repeatedly sieving and washing the macerated peas. Purified CWM contained no starch and had a low protein content (5.30%). The composition of pea CWM and pea hulls was compared. Pea CWM contained mainly pectic substances and hemicellulose, whereas the major constituent of pea hulls was cellulose. CWM contained 44.3% neutral detergent fiber. Therefore, CWM contents of pea cotyledons or air-classified protein concentrates were estimated by multiplying their respective neutral detergent fiber values by 2.26. The CWM value for pea cotyledons obtained by the isolation procedure was in good agreement with the calculated value. When calculated CWM values were summed with the other constituents of either flours or concentrates, the sum of components was nearly 100%.
