Abstract

A simple method of dehulling and demucilaging of linseed was developed. Solubility of the proteins of the linseed meal in water, 0.5 and 1.0 M NaC1, and 2% sodium hexametaphosphate solutions was determined in the pH range 2-12. The solubility was minimum around pH 3-6 and maximum around pH 8.0. The solubility minimum shifted to pH 0.5-4.5 in 1 M NaCl and to 0.6-5.3 in 2% sodium hexametaphosphate. The total proteins were characterized by techniques of gel filtration, ion-exchange chromatography, electrophoresis, and ultracentrifugation. The presence of at least three components was observed. The meal extracts showed proteolytic and trypsin inhibitor activities but no hemagglutinating activity. Amylase and amylase inhibitor activities were not detected.
