Abstract
The invention provides protein adhesives, and methods of making and using such adhesives. The protein adhesives contain a protein-bonding agent and plant protein composition, such as an isolated water-soluble protein fraction or ground plant meal obtained from plant biomass. The protein-bonding agent can be an anhydride compound, carboxylic acid compound, carboxylate salt compound, or combinations thereof. The protein adhesives are useful in bonding together lignocellulosic materials and other types of materials.
