	abstract = {<p>Environmental concerns about natural adhesive materials are leading to an increasing interest towards the development of ecological products. The development of new value-added uses for wheat proteins led us to develop protein-based wood adhesives. Different protein cold-setting resins were formulated by reacting the protein hydrolysates with different aldehydes (formaldehyde, glyoxal and glutaraldehyde). Wood bonded with cold-setting protein adhesive with different aldehydes met the requirements for interior and exterior conditions, and the characterization was similar to those of conventional PRF (phenol-resorcinol-formaldehyde) adhesives. As the results indicate, both glyoxal and glutaraldehyde are able to react with wheat protein hydrolysates and are viable alternatives to formaldehyde and prospectively seem more environmentally friendly. Matrix-assisted laser desorption ionisation time-of-flight (MALDI-TOF) analysis allowed the identification of the main oligomer species obtained. The analysis showed that resin prepared with glutaraldehyde is not a simple mix of resorcinol-glutaraldehyde oligomers and amino acid, but a much more complex combination of various species including amino acid-glutaraldehyde and amino acid-resorcinol oligomers.</p>},
