✦ Synopsis

The effect of phytate on the solubility of the sunflower seed proteins V. P. BULMAGA, N. A. LAPTEVA and I. A. VAINTRAUB I IS protein of the sunflower seed is precipitated by phytate at pH 2.0,'a protein-phytate complex being formed thereby. The number of the phosphate groups bound by the time the precipitation is completed is less than one half of that of the basic groups of the 1 IS protein. The insolubility of the complex formed interferes with the acid extraction of protein from the sunflower meal and solvent cake. The protein extractability increases sharply after the removal of the phytate.

The total salt-extractable protein from seeds of important cultivated legumes and sunflower kernels has a tryptophan content ranging from 0.91% (bywt) for chickpea (Cicer arietinum) to 1.99% (bywt) for green gram (Vigna radiata). In species with substantial albumin fractions, the tryptophan content
