Determination of Tryptophan in Corn ( Z e a mays) Joseph R. Spies
A method is described for the determination of tryptophan in corn proteins which are solubilized by Pronase hydrolysis and the hydrolyzate is analyzed colorimetrically. The Pronase-hydrolysisfollowing-water-extraction procedure is an accurate determination of the tryptophan content of components containing 84 to 89% of the total nitrogen of corn. The Pronase-hydrolysis-without-prior-

ore accurate and convenient methods for the determination of tryptophan in corn are needed for use in genetic and nutritional studies. Lyman et al. (1956) determined tryptophan in corn and other farm feeds by microbiological analysis of their alkaline hydrolyzates. In addition to possible losses of tryptophan during alkaline hydrolysis of complex mixtures, the microbiological method of analysis. while generally reliable, is not so convenient as colorimetric analysis. However, colorimetric determination of tryptophan in corn presents difficulties not found in similar analysis of purified proteins owing t o the low tryptophan content (
