Soft white winter .wheat flour was reacted with small amounts of 4N hydrochloric acid in a ribbon mixer to produce 30-lb. batches of a material similar to commercial products in paste viscosity and effectiveness as a tub-sizing agent. Although viscosity specifications were met by blending, viscosity varied from run to run with spraying quality, temperature, time, and acid concentration. An acid-modified flour was also prepared from gaseous hydrogen chloride.
