摘要
A modified vegetable protein adhesive binder and process for its production is disclosed comprising; forming a slurry of a urease containing vegetable protein material having a proteinaceous solids content of 10 to 30% by weight and including in said slurry a quantity of water soluble silicate to minimize foaming during reaction of the protein material. Urea is then added which reacts with the urease to liberate ammonia from the urea and raise the pH of the slurry to above about 8. The slurry having an alkaline pH is reacted with an oxidizing agent to modify the protein, followed by heating of the modified protein at a temperature of 220-320 DEG F. The modified protein material is then cooled and dried to result in a protein adhesive binder with excellent rheological properties and good coating characteristics.
