Abstract
Soaking in dilute alkali, followed by drying at elevated temperatures, was used to reduce the amount of assayable tannin in high-tannin sorg hum. Sorghum tannin levels were reduced by up to 88% by treatment with ammonium hydroxide (0.01-1 M) for periods of up to 20 days. Soaking a nd drying temperatures between 25 and 50 degrees C were evaluated. Inc reased drying temperatures decreased ammonia levels in the flour.
